Lacking Bats, a particular collection this week in The Athletic, explores how baseball’s profound metamorphosis over the past 20 years traces again to at least one easy concept — maximizing strikeouts in any respect prices — that turned an industry-wide obsession. Discover the whole collection right here.
The San Diego Faculty of Baseball was backed by hitting stars akin to Tony Gwynn and Alan Trammell, however it was the pitching minds that gave the early Eighties baseball camp its appeal — and its legacy.
Brent Strom and Tom Home had been teammates on the College of Southern California after which, later, journeyman pitchers within the main leagues. Except for lineage, in addition they shared deep-seated hunches that there was extra to study baseball than earlier generations had taught.
So when the day’s instruction was over, they sat within the dugouts of Grossmont Faculty or ventured to an area watering gap, tossing concepts backwards and forwards: the issues they cherished in regards to the sport, the issues they thought have been improper, the issues they wished to vary.
As soon as, throughout a child bathe for one more coach’s spouse, the boys have been scolded after they have been discovered within the nook of a room, taking part in again movie of pitchers. They have been all obsessives, and the San Diego Faculty of Baseball was their offseason oasis — a spot the place they may collect and focus on, with out judgment and scorn, among the very ideas that many years later would alter the stability of baseball.
“A summit,” Home known as it, “of good baseball minds.”
Earlier than PITCHf/x and Statcast might measure progress, earlier than web message boards and social media might create converts that will unfold the brand new gospel, earlier than there have been gleaming pitching labs and assume tanks like Driveline, earlier than the likes of the Rays, the Astros and the Guardians embraced the primacy of lacking bats and superior the science of pitching from the darkish ages, there have been solely tiny pockets just like the San Diego Faculty of Baseball.
They have been havens for the small band of devoted contrarians that flocked to those protected areas many years earlier than the baseball world might even start to reckon with their concepts. Whereas the sport regurgitated tried-and-true rules — preserve the ball down, pitch to contact, throw excessive — these males puzzled if there could possibly be a greater method.
“The era that was my pitching coach actually resisted something new,” Home mentioned. “They wished to have it’s precisely prefer it was since Babe Ruth’s time.”
But there was a value to pay for individuals who dared to problem conference. They have been mocked. They have been ostracized. They have been forged apart, their careers hampered.
They have been additionally confirmed proper.
“The identical stuff I used to be instructing years again that received me fired,” Strom mentioned, “now it’s the norm.”
At this time, Strom is thought to be one in all baseball’s finest coaches and a key determine in trendy pitching historical past. When most pitching coaches harped on sinkers and sliders and dotting the skin nook, Strom noticed the effectiveness of the elevated fastball and preached the novel idea that pitchers ought to use their finest weapons as usually as potential.
Strom had a kindred spirit in Home, the eccentric coach who would quickly be among the many first to introduce expertise to the world of baseball. He believed there was extra to find out about pitching mechanics and the human physique because it pertains to baseball than earlier generations had cared to know.
“What movement evaluation did within the mid-80s was present us that almost all of what we have been really instructing and studying as pitchers and pitching coaches, our eyes have been mendacity to us,” Home mentioned.
Home and Strom would acquire disciples outdoors the mainstream, akin to Ron Wolforth, the founding father of Texas Baseball Ranch, the place instructors would use new strategies to coach pitchers to throw tougher than they’d ever thought potential.
“Once we began,” Wolforth mentioned, “the general thought course of in skilled baseball was that velo was one thing that can not be taught. You both had it otherwise you didn’t.”
That mixture — Strom’s techniques, Home’s use of expertise and Wolforth’s harness of velocity — turned the premise for strategies Ivy Leaguers in baseball’s entrance workplaces would at some point use to remodel pitchers into optimized strikeout machines.
However earlier than these concepts turned the norm, the boys who fostered new methods of interested by pitching have been baseball’s variations of Galileo. When the Seventeenth-century astronomer postulated the idea of a heliocentric universe, his concepts have been labeled silly and absurd. The Catholic Church thought-about him a heretic. His works have been banned and he was punished with confinement. Now, he’s thought-about the daddy of contemporary science.
“Are you telling me,” Wolforth joked just lately, “I’m going to be put beneath home arrest for the remainder of my life?”
After his middling pitching profession was over, Strom entered the teaching ranks, working for the Dodgers group within the Eighties. It was there his beliefs on pitching started to coalesce. He had grown up a faithful fan of Sandy Koufax, and one spring, when the Dodgers nice was in camp, he mentioned one thing that caught with Strom.
“You realize who throws sinkers?” Koufax requested. “Individuals who can’t throw fastballs.”
In these days with the Dodgers, Strom would take in the tales instructed by former gamers akin to catcher Johnny Roseboro, who usually talked of Koufax’s dazzling efficiency in Sport 7 of the 1965 World Collection. Koufax was pitching on two days’ relaxation. Arm ache had zapped the life from his curveball. Within the first inning, after Koufax saved shaking when Rosoboro known as for the curve, the catcher went to the mound and pivoted the sport plan. “We’ll blow ’em away,” he instructed the pitcher.

Koufax threw nearly fully fastballs that day, nearly completely up within the zone, and dominated. However all through the sport, what Koufax did was thought-about an anomaly — a operate of his distinctive expertise, not one thing that could possibly be discovered.
Strom didn’t see it that method. He started to theorize that many pitchers had an arsenal that will play higher atop the strike zone, utilizing four-seam fastballs that might seem as in the event that they have been rising to bowl over the bats of hitters. These pitches might come out of the identical tunnel as an influence curveball or slider. And if a pitcher was efficient with that elevated fastball or that energy breaking ball, he ought to use it as a lot as potential. Strom’s concepts have been forward of their time. However baseball wasn’t fairly prepared for them but, and he languished within the minors.
“I feel,” Strom mentioned, “I used to be a bit of too far out on the gangplank a bit of too early.”
In Texas, Home bumped into a lot the identical drawback. In 1985, Rangers normal supervisor Tom Grieve employed Home as pitching coach for supervisor Bobby Valentine. Grieve was 37, and Valentine was 35. They have been swashbucklers working with a restricted finances. They knew they wanted to be totally different.
By the mid-Eighties, Home had offered his stake within the San Diego Faculty of Baseball and brought out a second mortgage on his residence to put money into the Ariel System, a set of high-speed cameras that might detect actions the bare eye couldn’t.
Quickly, Home had transformed a closet within the bowels of Arlington Stadium right into a video room with VHS gamers and two small TVs. They put a satellite tv for pc atop the clubhouse so they may tape-record opponents’ video games. Home devoured the movie. He in contrast his pitcher’s deliveries to tennis gamers and javelin throwers — stiff entrance legs, agency entrance sides. When he would arrange cameras alongside the first- and third-base strains earlier than video games, most individuals ignored him just because that they had no concept what he was doing or dismissed him due to his mediocre observe report as a pitcher.
“My drawback early on was I knew, as a result of I noticed the science, however I wasn’t sufficient of a profile man,” Home mentioned. “If I had been a Sandy Koufax, a Tom Seaver in that period, they in all probability would have listened a bit of bit extra.”
At this time, Tom Home is acknowledged as a guru in each baseball and soccer circles. That wasn’t all the time the case. (Mark Boster / Los Angeles Instances through Getty Photos)
Home first used his movement evaluation to rethink the premise of pitching mechanics. Pitchers, for instance, had lengthy been taught to throw straight overhead. By means of his video evaluation, Home realized that most of the sport’s finest threw from a pure three-quarters supply. However as a result of the methodology was odd, few purchased into his discoveries.
The Rangers would arrange a “calibration dice” manufactured from PVC pipes of their bullpen earlier than pitchers would carry out their movement in entrance of Ariel System cameras. Home believed the evaluation that got here within the type of computer-generated stick figures might assist pitchers throw the ball tougher, command the ball higher or make their arms last more.
“There weren’t many individuals coming over and saying, ‘What are you guys doing over there within the bullpen? We wish to do this, too,’” Valentine mentioned. “It was extra like seeing what we have been doing after which gathering with their buddies. ‘Hey, have a look at what these idiots are doing.’”
Home saved pitch counts in addition to diet logs. The whole lot was documented and analyzed. Quickly, he was having his pitchers throw footballs as a coaching technique. The tightness of a soccer’s spiral served as a option to iron out mechanical deficiencies. Home believed the soccer’s weight helped construct practical energy. However when opposing coaches noticed Rangers pitchers doing Joe Montana impressions within the outfield earlier than video games, they labeled the coach a wild eccentric. And when an opposing lineup would pummel one other Rangers pitcher, media pundits had a simple goal: How did that look on video?
“I used to be pissed off at instances,” Home mentioned. “I had my emotions damage. And I received indignant at folks. However I by no means didn’t belief the worth of my data.”
Right here’s an incredible video from method again within the day the place I used to be speaking about utilizing video and 3D movement evaluation together with your VCR to make you a greater pitcher.

The issue was that Home’s pitching staffs by no means amounted to a lot. They led the league in walks yearly from 1986-89. Their quirky coach could have centered extra on processes and concepts than on tangible outcomes. Not all gamers absolutely grasped his ideas.
“I used to assume that that was the one flaw that Tom ever had, is that he was so satisfied that he was so right that he wasn’t going to let a lot else get in the way in which of his thought,” Valentine mentioned. “His thought was what was filling the air. It wasn’t actually a dialog.”
Halfway by the 1992 season, the Rangers fired Valentine. By the subsequent yr, Home was reassigned to a place within the minor leagues. He by no means coached one other day within the majors.
His concepts, nonetheless, have been beginning to unfold.
In 1999, Ron Wolforth, a former journeyman faculty pitcher who had coached softball at Nebraska, printed a ebook with an extremely boring title: “Bettering Your Pitching Mechanics IQ: The 36 Positional Relationships That Impact Efficiency.”
An avid fan of Home, Wolforth traveled to a operate in Madison, Wisc., the place Home was talking. His purpose was at hand Home his ebook and have the famed coach put a face with the identify. He succeeded, and shortly Home was giving an illustration and utilizing the ebook as a makeshift residence plate.
Home later returned residence and flipped by Wolforth’s tome. He known as quickly after. “Hey,” Home instructed Wolforth, “you might have some attention-grabbing concepts.”
Wolforth quickly joined Home’s Nationwide Pitching Affiliation — a type of assume tank devoted to sharing data and dealing to standardize coaching strategies to maintain younger athletes wholesome.
Wolforth turned one in all its most omnivorous thinkers, trying far and broad to seek out new strategies of increase pitchers’ our bodies. He studied the teachings of a Connecticut engineer named Paul Nyman, who believed velocity could possibly be skilled by intent, and that despatched Wolforth in direction of weight coaching and the advantages of throwing weighted balls. He studied Dr. James Andrews and prioritized doing rehab-like coaching earlier than accidents occurred. He investigated the concepts of Mike Marshall, the 1974 Cy Younger winner who was attuned to ideas like spin axis and seam-shifted wake earlier than nearly anybody else. He was fascinated by the coaching strategies of the Soviet navy. He started to formulate his personal pitching dogma, one which tapped all these sources and posited that velocity was not set in stone.
Finally, Wolforth began taking a few of his concepts to NPA colleagues. And even among the many sport’s extra progressive thinkers, he was rejected.
“The pure religion was, ‘Get on the mound, discover your option to have a repeatable supply, and should you threw it tougher, it was as a result of God touched your arm and also you have been simply genetically gifted,’” Wolforth mentioned. “And I mentioned, ‘That’s crap.’”
To Wolforth, velocity was not one thing solely distributed by the almighty. He by no means anticipated to make each pitcher into Nolan Ryan, however he believed pitchers might acquire a couple of extra miles per hour on their fastballs, if solely they may strengthen their engines and arrange their our bodies within the right method.
In 2003, Wolforth and his spouse Jill emptied their financial savings and remodeled a 20-acre plot outdoors of Montgomery, Texas, right into a facility with a glorified barn and a metal hut with arched ceilings.
Pupils who endured Wolforth’s summer season program at Texas Baseball Ranch studied linked actions and drilled with one-legged squats, weighted balls, weighted gloves, shoulder tubes and different uncommon instruments. Most pitchers certainly gained velocity. Really pitching was a distinct matter.
“Early on, we had plenty of guys get plenty of curiosity, then go into professional ball and get launched inside a yr or two as a result of they couldn’t throw it over the white factor,” Wolforth mentioned. “So it was slowly modified. I mentioned, ‘OK, we’re going to have so as to add in plenty of different stuff to this.’”
But Wolforth was on to one thing. He was proving velocity could possibly be a teachable talent.
Whereas the Ranch was churning out its first graduates, Strom was confronting the fact that his profession had stalled; after leaving the Dodgers, he went on to an extended record of teaching positions, together with stints because the major-league pitching coach with the Astros in 1996 and the Kansas Metropolis Royals in 2000-01. In 2002, he turned the minor-league pitching coordinator for the Montreal Expos.
In Houston, Strom was fired after one season. With the Royals, he was fired after two seasons. With the Expos, who turned the Nationals, he was fired after his fourth yr.
“I used to be out of the sport for a pair years,” Strom mentioned. “Bought plenty of sideways glances. That type of stuff. It wasn’t simple.”
Strom finally discovered himself out of labor. For greater than a yr, he helped his spouse run a canine grooming enterprise in Arizona.
He was lastly introduced again into the sport by the Cardinals, the place a comparatively new worker thought he noticed one thing within the longtime coach’s philosophies. Nonetheless, Strom says he was solely allowed to work with the staff’s low-level prospects. Cussed in his convictions, he challenged the group’s sinker-slider obsession and sometimes clashed with the Cardinals’ brass, together with major-league supervisor Tony La Russa and pitching coach Dave Duncan.

Strom usually thinks again to a gathering in 2008. The Cardinals have been a corporation constructed on old-school, fundamentalist beliefs. Sinkers and sliders meant to be put in play. Low and away, low and away, low and away.
No staff threw extra sinkers on the backside of the strike zone. Solely two groups that season generated fewer swinging strikes.
On this assembly, a Cardinals official stood in entrance of a room filled with coaches. “Does anyone know the batting common on fly balls?” the official requested. “Does anyone know the batting common on groundballs?”
As Strom remembers it, the official knowledgeable the room that major-league batters hit .222 on groundballs however .417 on fly balls.
Strom, ever the contrarian, raised his hand.
“That’s bulls—,” he mentioned.
Strom requested whether or not a line drive ought to rely as a fly ball. The official mentioned sure. And right here, Strom realized, was one of many sport’s prevailing logical fallacies. In 2008, major-league batters really hit solely .222 on fly balls and pop-ups. On groundballs, they hit .241. On line drives, they hit an eye-popping .728.
Pitchers, Strom then theorized, mustn’t concern fly balls. They need to not pitch solely to the decrease third of the strike zone. They need to not devise their complete arsenals in hopes of inducing contact and producing outs on the bottom. There could possibly be one other technique, one which concerned figuring out the pitches hitters battle to place in play and attacking with these pitches relentlessly.
“Once I introduced this idea to the Cardinals, it was utterly adversarial to what they have been instructing,” Strom mentioned. “You realize what occurs whenever you attempt to induce tender contact? You get onerous contact. … In case you don’t strike out sufficient folks, each ball that’s hit has the potential to be a base hit. I’ve but to see a man attain first base on a strikeout.”
As Strom stirred up bother, the Cardinals worker who initially employed him noticed rising worth in his revolutionary concepts and the info that appeared to assist them. When he received his personal staff to run, he would bear in mind the outspoken coach with the daring new concepts.
“Thank God,” Strom mentioned, “for Jeff Luhnow. He saved my ass.”
By 2008, phrase was spreading that the pupils at Wolforth’s ranch have been seeing their velocity numbers rise, and Wolforth was contracted by a major-league membership to talk at spring coaching. He was standing in a hallway earlier than his speech when he overheard two members of the group speaking, oblivious to who Wolforth was.
One man requested the opposite: “Do you wish to go golf?”
“No,” the opposite mentioned. “I can’t. I gotta go take heed to Johnny f—in’ Guru.”
On the time, many of the baseball institution nonetheless thought that method — that these preaching these new concepts have been outsiders who had little understanding of how the sport labored. However a couple of organizations have been beginning to see the probabilities.
Luhnow had left the Cardinals to take over baseball operations for the Astros in 2011. Quickly, he introduced Strom on board and empowered him to unfold his teachings all through the group. In Houston, Strom lastly had a house for his concepts.
“Brent Strom was the primary pitching coach that got here to me and was preaching excessive targets, was preaching excessive within the strike zone and excessive out of the strike zone,” mentioned A.J. Hinch, then the supervisor of the Astros.
Strom’s teachings have been embraced and even furthered by the staff’s data-driven entrance workplace. Earlier than they have been villains mired in a historic dishonest scandal, the Astros have been innovators who invested in expertise all through their system like no different staff.
“Their analytics division simply enlightened me to no finish,” Strom mentioned.
Edgertronic cameras allowed folks like Strom to overview mechanics, grips and launch factors in additional granular element. The Astros obsessed over TrackMan knowledge. Houston stationed developmental coaches at every minor-league affiliate to assist translate the numbers to gamers. It was a system Home would have salivated over in 1986.
The Astros, too, have been amongst MLB golf equipment that shaped a relationship with Texas Baseball Ranch. Wolforth’s enterprise took off across the time one pupil, a UCLA pitcher named Trevor Bauer, proved how a lot a thrower’s stuff might enhance by coaching the proper method and embracing science. A Sports activities Illustrated article catapulted the power to fame.
“Lots of people thought it was only a one-off, like we simply occurred to catch lightning in a bottle,” Wolforth mentioned.
The {industry} quickly determined in any other case. All-Star pitcher C.J. Wilson was amongst those that learn the story. Wilson was one other man forward of his time, a pitcher who requested groups for TrackMan knowledge earlier than it was available to gamers and was rejected.
“It was loopy originally,” Wilson mentioned, “as a result of I actually had entrance workplace folks and coaches go, ‘Cease asking about this as a result of we’re not going to offer it to you.’”
After the 2011 season, Wilson sought out the Texas Baseball Ranch as a result of he was drawn to Wolforth’s mental view on pitching. Wilson stayed in a lodge down the highway and went by Wolforth’s program, searching for primarily to enhance the spin effectivity on his changeup and looking for drills to assist preserve his decrease half wholesome. He took a few of what he discovered into his 2012 season with the Angels, the place he made his second All-Star Sport.

Scott Kazmir was a two-time All-Star, however at age 27, he discovered himself practically out of baseball. Along with his fastball velocity zapped down into the 80s, Kazmir trekked to Wolforth’s ranch looking for a resurrection. He returned to the foremost leagues touching 95 and was an All-Star once more in 2014 at age 30. The Astros traded for him the subsequent summer season.
Tales of successes like these started to unfold. In 2008, when Wolforth spoke to that staff throughout spring coaching, he started his speech by introducing himself. “I’m Ron Wolforth,” he mentioned. “However a few of you already know me by my different identify, ‘Johnny f—in’ Guru.’”
The joke disarmed the skeptical viewers. Inside a couple of years, such techniques have been now not essential.
“Now, impulsively, I’m not just a few smug prick that’s telling them that I’m good and so they’re dumb,” Wolforth mentioned. “That was round 2008. However by 2011, 2012, 2013, I had no such issues. Folks have been anxious to listen to what I used to be going to say.”
With word-of-mouth spreading and forward-thinking groups just like the Astros, Guardians, Yankees, Dodgers, and Rays starting to put money into pitching improvement, concepts traveled at warp velocity. The web supplied an outlet for tinkerers to analysis and swap concepts like by no means earlier than.
“I feel it occurred just like the Huge Bang Principle,” Home mentioned. “It occurred without delay. There have been bits and items that everyone contributed to.”
Now, the Texas Baseball Ranch web site boasts of 121 MLB draft picks and 20 pupils who’ve reached the 100-mph threshold. By the mid-2010s, major-league groups used TBR instructors as consultants. Strom and Wolforth are shut buddies. Managers akin to Hinch and Cleveland’s Terry Francona have been amongst those that traveled to the services and discovered extra in regards to the coaching strategies. The Ranch was a precursor to Driveline, the efficiency lab based by Kyle Boddy, a poker participant who as soon as frequented baseball message boards and shortly represented the subsequent wave of outdoor disruption. When Wolforth gave his Johnny F’n Guru speech, the typical velocity for a four-seam fastball within the main leagues was 91.9 mph. By 2023, it was 94.2 mph.
All this led to validation for the kind of males who had lengthy sought to vary the sport.
Home, as soon as labeled a flake, went on to make use of his strategies to tutor pitchers and quarterbacks alike. He turned well-known for his work with Randy Johnson and NFL stars akin to Tom Brady and Drew Brees. His set of high-speed cameras represented an ancestor to applications like TrackMan, Hawk-Eye and KinaTrax that immediately measure each motion and dominate our understanding of the sport. Home’s tutorial interpretations of pitching mechanics and his heady technical explanations confirmed how pitchers might transfer their our bodies extra effectively.
Frowned upon on the time by the baseball institution, Home had really laid the groundwork for the way pitching coaches would at some point do their jobs. Lots of the concepts he preached with the Rangers are actually core values in MLB coaching applications.
“It took somebody both as cussed as me or as fortunate as me or possibly as dumb as I used to be to proceed to push the envelope,” Home mentioned. “Even once I was getting booed or yelled at.”
Locations like Wake Forest now have constructed revolutionary pitching labs stuffed with expertise and movement evaluation. An understanding of the physique’s kinetic chain has grow to be an avenue into the world of baseball. Two years in the past, the Detroit Tigers employed a former faculty kinesiology professor named Robin Lund as one in all their pitching coaches.
“As science and expertise have been creeping into the new-school instructors, every part we have been speaking about method again when has turned out to be true,” Home mentioned.
That has left these former iconoclasts in fixed demand. By 2021, the Astros fell in Sport 6 of the 2021 World Collection, and Strom was trying ahead to having fun with retirement at his beachfront rental in Mexico. He had helped Houston to 3 World Collection appearances, and at 73, he thought it was time to maneuver on. However when the Arizona Diamondbacks known as and supplied him a job, he couldn’t resist.
When Strom got here to Arizona earlier than the 2022 season, the Diamondbacks threw the league’s lowest proportion of what Strom thought-about an elevated fastball — a pitch at the least 3 ft and three inches off the bottom. The following yr, the typical top of D-Backs’ fastballs went from 2.5 ft off the bottom to 2.6. The Diamondbacks employees threw fewer fastballs however started elevating them extra. The batting common in opposition to these pitches, in flip, dropped 46 factors.
In Arizona, Strom mentored pitchers akin to Zac Gallen, who started throwing his fastball up within the zone extra usually but additionally practically doubled his curveball utilization. “He’s burdened throwing your finest pitch as a lot as potential,” Gallen mentioned.
Final October, Strom’s Diamondbacks reached the World Collection. Gallen completed third in voting for the Nationwide League’s Cy Younger Award. As soon as a pariah, the 75-year-old pitching coach turned a fixture on the sport’s apex.
“For all of the credit score I seemingly get now,” Strom deadpanned this winter, “I’m doing the identical s— I did again then.”
