Platoon advantage didn’t decide David Fry’s biggest postseason at-bat. One misplaced fastball did.
Cleveland trailed Detroit 3-2 in the seventh inning of Game 4 of the 2024 American League Division Series. The Guardians were seven outs from elimination. Steven Kwan stood on first with two outs, and manager Stephen Vogt needed someone to face Tigers left-hander Sean Guenther.
Vogt sent Fry to pinch-hit for Kyle Manzardo. Detroit manager A.J. Hinch answered with right-hander Beau Brieske.
The move erased Cleveland’s platoon advantage. Worse, Brieske had struck out Fry in all three of their previous meetings that season.
Fry fell behind 0-2. He fought off pitches, watched a slider escape the catcher, then punished a fastball that caught too much plate.
The ball sailed into the left-field seats. Cleveland suddenly led 4-3.
That swing captured the problem every October manager faces. Handedness favors one hitter, recent results favor another, and the opposing pitcher can change the entire calculation.
Platoon advantage versus batter form isn’t a contest between statistics and instinct. It’s a question of which evidence deserves the manager’s trust.
Why handedness matters, but doesn’t settle the argument
Baseball managers have spent generations searching for favorable left-handed and right-handed matchups.
The reasoning makes sense. Most hitters perform better against opposite-handed pitching. A left-handed batter typically sees a right-hander’s breaking ball move toward his swing path. Against a left-handed pitcher, that same breaking ball often sweeps away.
The advantage can influence contact quality, strikeout rates, and extra-base production. Teams build benches around those differences, keeping particular hitters available for late-inning assignments.
And they chase those matchups constantly.
FanGraphs analyst Davy Andrews found that hitters enjoyed the platoon advantage in 54.6% of major league plate appearances during 2025. Through June 7, 2026, that share had climbed to 57.5%.
More than half of all plate appearances already favored the batter’s handedness, and teams were pushing that edge further.
But finding the favorable side doesn’t guarantee finding the better hitter.
An established right-handed slugger might handle right-handed pitching better than a weaker left-handed substitute. Another hitter might possess an unusually effective swing against breaking balls from his own side.
Managers must consider the players’ overall abilities before assigning value to the matchup.
Consider two hypothetical hitters. One projects for a .330 weighted on-base average against the pitcher. His potential replacement projects for .320, even after receiving credit for the better handedness matchup.
The substitution would give the manager the platoon advantage while reducing projected offensive production.
That’s a bad trade.
The objective isn’t to win the matchup on paper. It’s to give the team its best chance to score.
October forces managers to make that distinction with little time and few opportunities to correct a mistake.
Why a hot streak can fool even experienced managers
A hitter reaches October after collecting eight hits in his previous 20 at-bats. He looks comfortable, attacks pitches early, and seems to find every opening in the defense.
His batting average says he’s hot.
But twenty at-bats tell a manager very little about what will happen next.
A broken-bat single counts the same as a line drive. A grounder that sneaks between two infielders can improve a player’s average without revealing anything about his swing.
Meanwhile, another hitter might go two-for-15 while repeatedly driving balls directly at defenders.
The box score favors the first player. The quality of contact might favor the second.
Even a full season can leave managers guessing about a hitter’s true platoon ability.
FanGraphs’ research illustrates just how stubborn that uncertainty can be. When estimating a left-handed hitter’s performance against southpaws, analysts blend his observed results with the equivalent of roughly 1,000 league-average plate appearances. For right-handed hitters facing lefties, that regression weight rises to approximately 2,200 plate appearances.
Those aren’t mandatory sample sizes before a manager can make a decision. They show how much statistical caution even an established hitter’s record demands.
Now imagine judging someone’s ability from four games in October.
A handful of strikeouts might dominate the conversation. One bloop single could change the narrative overnight. Neither tells the full story.
The numbers underneath the batting average
Hard contact can survive a cold week.
A hitter who keeps driving baseballs into the outfield shouldn’t automatically lose his job because defenders keep catching them. That’s where Statcast gives managers another way to evaluate what they’re seeing.
Baseball Savant’s data reveals how hard a ball leaves the bat and the angle at which it travels. Expected weighted on-base average, or xwOBA, goes further. It uses contact characteristics, along with walks and strikeouts, to estimate a hitter’s underlying offensive production.
The distinction matters when results stop matching the quality of the swings.
Suppose a struggling hitter keeps producing 102 mph line drives. His batting average might look terrible, but the contact offers reason for patience. Another player could collect four singles on softly hit grounders without showing the same underlying strength.
Neither example guarantees what happens tomorrow.
But they give the manager more to work with than a batting average covering a dozen plate appearances.
Coaches can also study bat speed, swing decisions, and performance against particular pitch shapes. Video might reveal an injury-related adjustment or a hitter arriving late against high fastballs.
That information carries more weight than a simple declaration that someone has a hot hand.
Still, managers cannot dismiss recent performance entirely.
A player who has lost bat speed because of an injury presents a different problem from someone experiencing ordinary statistical variance.
The challenge lies in separating a meaningful physical change from the noise of a small sample.
David Fry exposed the limits of matchup history
Return to Comerica Park in October 2024.
Detroit believed Brieske offered the right answer against Fry. The Tigers reliever had struck him out three times, including twice earlier in the Division Series.
Even Cleveland understood the assignment would be difficult.
Fry had enjoyed enough success against right-handed pitching that Vogt trusted him regardless of the apparent disadvantage.
Brieske quickly worked ahead 0-2. His fastball reached the upper 90s, and he had the slider to finish the at-bat.
Fry refused to chase.
A slider in the dirt skipped past catcher Jake Rogers, sending Kwan to second. The next mistake proved more costly.
Brieske wanted a fastball up and away. Instead, he brought it into the part of the strike zone Fry could attack.
The Guardians’ pinch-hitter drove the pitch over the left-field wall.
Brieske later acknowledged to MLB.com that he had missed his intended location. His execution, rather than the broader matchup strategy, had failed.
Fry wasn’t finished.
With a runner on third in the ninth, he laid down a safety squeeze that brought Brayan Rocchio home. Cleveland held on for a 5-4 victory, forcing a deciding Game 5.
His performance offered a sharp lesson in October decision-making.
The three previous strikeouts were genuine evidence, but they came from a tiny sample. Brieske’s pitch quality mattered. Fry’s ability to handle right-handed pitching mattered, too.
A few earlier at-bats couldn’t outweigh everything else.
Fry won the moment because he recognized a mistake and hit it hard. The matchup numbers never promised Brieske would execute every pitch.
Alek Thomas gave Arizona the matchup it wanted
A year earlier, Arizona manager Torey Lovullo faced a different version of the same decision.
The Diamondbacks trailed Philadelphia 5-3 in the eighth inning of Game 4 of the 2023 National League Championship Series.
Lourdes Gurriel Jr. had doubled, and Evan Longoria stood at the plate. Lovullo prepared left-handed outfielder Alek Thomas to pinch-hit against Phillies right-hander Craig Kimbrel.
But the manager had another option.
If Longoria reached base, Lovullo considered using Jordan Lawlar to lay down a bunt. The sacrifice could advance runners into scoring position and create another opportunity to tie the game.
Longoria flied out. Lovullo abandoned the bunt possibility and let Thomas swing.
The left-handed hitter worked the count full against Kimbrel. Then he drove a 94 mph fastball over the right-center-field wall and into the swimming pool at Chase Field.
Two runs. Tie game.
Arizona added another run and won 6-5, leveling the series at two games apiece.
Unlike Fry’s confrontation with Brieske, Thomas received the favorable lefty-righty matchup. The result also rewarded Lovullo for choosing a hitter who could erase the deficit with one swing.
The circumstances demanded more than a marginal improvement in on-base probability.
Arizona needed two runs. Thomas offered the ability to produce both immediately.
His home run demonstrated why managers must evaluate the type of offense they need, not just a hitter’s likelihood of reaching base.
A contact specialist might have extended the inning. Thomas changed the score.
Neither approach guarantees success. The correct choice depends on the game situation and the quality of the available hitters.
The Dodgers proved swing shape can outweigh handedness
A manager can gain even more information by examining how a hitter swings against a particular pitcher’s repertoire.
Dave Roberts supplied an example during Game 2 of the 2022 National League Division Series against San Diego.
The Dodgers trailed by one run in the eighth inning. Left-handed closer Josh Hader stood on the mound, and Cody Bellinger was due to hit.
Roberts decided to pinch-hit.
Chris Taylor offered an obvious option. He batted right-handed, had an established offensive track record, and possessed more power than backup catcher Austin Barnes.
Roberts chose Barnes.
The decision surprised observers because both replacements batted right-handed. Neither offered a different platoon advantage.
The explanation came from their swings.
Roberts believed Barnes’ short, relatively flat bat path matched Hader’s delivery better than Taylor’s pronounced uppercut.
MLB.com’s examination of postseason managerial decisions later highlighted the contrast. Barnes had the flattest swing on the Dodgers that season, while Taylor featured one of the steepest uppercuts.
Roberts wanted a hitter whose swing could reach the pitch he expected.
Barnes flew out.
The unsuccessful result didn’t make the reasoning irrational. It showed how much uncertainty remains after a manager identifies a promising matchup.
Hader still had to deliver the pitch. Barnes still had to make contact.
Against another pitcher, Taylor’s swing could have presented the greater threat.
Pitch shape, release angle, and swing path can make two same-handed hitters entirely different options.
A manager who looks only at handedness misses those differences.
The math behind a pinch-hit decision
The statistical calculation starts with projected offensive production.
A single and a home run both count as hits, but no manager values them equally. Weighted on-base average, or wOBA, accounts for that difference by assigning offensive outcomes values based on how much they contribute to scoring.
Walks matter. Doubles carry more weight than singles. Home runs receive greater credit still.
FanGraphs uses those values to estimate offensive runs above average. Its wOBA scale also allows analysts to translate a difference between two hitters into an approximate run value.
Imagine a manager comparing two options before a critical plate appearance.
The starter projects for a .315 wOBA against the opposing reliever. A bench player projects for .335 after accounting for the pitcher’s repertoire, handedness, and the hitter’s expected ability.
That 20-point advantage sounds substantial.
Spread over hundreds of plate appearances, it could become meaningful. But October asks the manager to act on one swing.
With an illustrative wOBA scale of 1.25, the projected difference translates into approximately 0.016 expected runs for that plate appearance in a context-neutral comparison.
That’s sixteen thousandths of a run.
Hardly the kind of number that makes a stadium erupt.
Yet managers routinely face decisions where one modest statistical edge represents their best available choice. The problem is knowing whether the gain outweighs everything else the substitution might cost.
And those context-neutral numbers don’t account for the score, inning, or baserunners.
A tie game in the ninth demands a different calculation from an ordinary plate appearance in the third.
The inning changes the value of every outcome
Imagine a team trailing by one run with the bases loaded and one out.
A pinch-hitter who makes frequent contact might offer a reasonable chance to tie the game with a sacrifice fly. Another hitter could generate more strikeouts but offer a better chance to clear the bases.
Which player helps more?
The answer depends on the probability of each outcome and what that outcome does to the team’s chances of winning.
Run expectancy measures the average number of runs teams score from specific base-and-out situations. Win probability adds the inning, score, and other game circumstances.
A solo homer in the third inning matters. The same homer in the bottom of the ninth can end the game.
Those events share the same basic batting result but carry different consequences for winning.
Managers therefore need projections for more than overall production. They need to estimate the likelihood of a walk, strikeout, single, extra-base hit, or ball in play that scores a runner.
Contact and power create different opportunities.
The right hitter depends on which outcomes the team needs most.
The bench carries a cost beyond one at-bat
A pinch-hit substitution can improve an immediate matchup and still create trouble later.
Once a manager removes a player from an MLB game, that player cannot return. The replacement also affects the defensive alignment and the remaining bench.
Consider a shortstop who provides outstanding defense but struggles against a particular right-handed reliever.
A left-handed bench bat might offer a better offensive projection. Removing the shortstop, however, could leave the team with a weaker defender for the final innings.
Extra innings would make the decision even more expensive.
The manager must consider both possibilities before making the move.
Pitching rules create another complication.
MLB’s three-batter minimum generally requires an entering reliever to face three batters or finish the half-inning, barring specified exceptions.
That restriction encourages managers to think beyond the next hitter.
A pinch-hitter might force the opposing manager to consider a pitching change that creates a better opportunity for someone else. In another situation, the bullpen simply lacks the flexibility to answer.
Those possibilities affect the entire sequence.
A good bench decision accounts for the next plate appearance without sacrificing too much value in the innings that remain.
Cleveland’s other October homer showed what one swing can change
Fry wasn’t Cleveland’s only postseason pinch-hit hero in 2024.
One week after his Division Series home run, the Guardians faced the Yankees in Game 3 of the American League Championship Series.
New York led 5-3 in the bottom of the ninth. Two outs separated Cleveland from a 3-0 series deficit.
Lane Thomas stood on second after a double. Yankees closer Luke Weaver needed one more out.
Vogt sent rookie Jhonkensy Noel to pinch-hit for Daniel Schneemann.
Noel batted right-handed. Weaver threw right-handed. Cleveland wasn’t chasing a favorable traditional platoon matchup.
The Guardians wanted power.
Noel had built his reputation on the ability to punish mistakes, even if his aggressive swing also exposed him to strikeouts.
Weaver threw a changeup over the plate.
Noel crushed it.
Statcast projected the ball to travel roughly 404 feet into the left-field seats. Progressive Field erupted as the Guardians tied the game, and Noel slammed his bat to the ground.
Cleveland won 7-5 in ten innings on another Fry home run.
The Noel decision illustrated something that a season-long batting projection cannot fully capture in one particular game state.
Cleveland needed two runs to tie. A single from Noel would have required at least one more productive plate appearance.
His power offered a direct route back into the game.
Vogt accepted the strikeout risk because a home run had enormous immediate value.
Noel delivered exactly the kind of hit his manager sought.
The result doesn’t establish that a power hitter always represents the best choice in those situations. It demonstrates why the score can change the value of different offensive skills.
What the next October decision will demand
Managers have more information about hitters than ever before. They can compare handedness splits, examine swing paths, track contact quality, and identify weaknesses against specific pitch shapes.
But all that information still has to produce one decision.
A bench coach can show the manager a projected advantage. The hitting coach might see something different in the incumbent’s swing. Meanwhile, the opposing bullpen can alter the matchup before either player reaches the batter’s box.
The pressure doesn’t make those disagreements disappear. It makes them harder to resolve.
Fry’s home run against Detroit showed why previous strikeouts cannot dictate the next matchup. Thomas demonstrated the value of finding both a favorable handedness matchup and the power to change the score.
Roberts’ choice of Barnes against Hader offered another lesson. A manager can identify a logical swing-path advantage and still watch the hitter make an out.
Noel’s homer showed how the game situation can make raw power more valuable than an ordinary contact advantage.
None of those examples gives managers a universal formula.
The next improvement in postseason strategy will likely come from better estimates of individual matchups. Teams already possess the tools to study bat speed, pitch movement, and contact quality in remarkable detail.
The difficult part remains deciding how much weight each measurement deserves.
Recent form can reveal a genuine problem. It can also disguise a healthy hitter experiencing bad luck. Career platoon numbers offer useful guidance, but even thousands of plate appearances cannot predict one specific swing.
And the opposing pitcher still has a say.
A perfect slider can beat a hitter who owns the statistical advantage. One poorly located fastball can erase an entire plan.
Somewhere this October, a manager will look toward his bench as a reliever finishes warming up. One hitter will keep his helmet on. Another will take a few final swings near the dugout.
The manager will have years of data, a handful of recent at-bats, and only seconds to decide.
He won’t know whether the next swing will work.
His job is to know why he chose the hitter taking it.

FAQs
What is the platoon advantage in baseball?
A hitter usually enjoys the platoon advantage when facing a pitcher who throws with the opposite hand. That matchup can improve contact and power.
Does a hot hitter make a better postseason pinch-hitter?
Not necessarily. A recent hot streak might reflect good luck. Managers also examine hard contact, swing mechanics, and the opposing pitcher’s strengths.
How do MLB managers decide when to use a pinch-hitter?
They compare hitter projections, handedness, pitch types, and the game situation. They also consider defense and how many bench players remain.
What is wOBA, and why does it matter for pinch-hitting?
Weighted on-base average values walks and different types of hits by their scoring contribution. It helps managers compare hitters beyond batting average.
Why did Cleveland use Jhonkensy Noel as a pinch-hitter in the 2024 ALCS?
Cleveland needed two runs to tie the game. Manager Stephen Vogt chose Noel’s power, and the rookie delivered a game-tying homer.
