Early-count swing percentages don’t sound particularly threatening until Corey Seager turns a 93.6-mph fastball into a 418-foot home run. On October 27, 2023, the Texas Rangers were two outs from losing Game 1 of the World Series. Arizona closer Paul Sewald had a 5-3 lead, and Globe Life Field could feel the night slipping away.
Seager stepped in with Leody Taveras on first. Sewald tried to elevate a four-seam fastball. The pitch stayed close enough to the strike zone for Seager to unleash his swing.
The baseball exploded off his bat at 112.6 mph. Seager screamed toward the Rangers’ dugout as the ball disappeared into the right-field seats. One pitch had erased Arizona’s lead.
Texas eventually won 6-5 in 11 innings, with Adolis García delivering the walk-off home run.
That swing wasn’t a reckless gamble. Seager had spent the season attacking pitches he could drive while refusing to chase the ones he couldn’t.
His approach exposed a larger change across Major League Baseball. The old instruction to take the first pitch no longer works against every opponent.
Sometimes the best pitch arrives before the hitter even breaks a sweat.
Why MLB Hitters Have Stopped Giving Away the First Pitch
For decades, working the count represented an essential part of offensive discipline. Hitters wanted to force starters into long innings, reveal their secondary pitches, and reach the bullpen.
That philosophy still matters. But modern pitching has changed the cost of waiting.
A hitter facing elite velocity might see a hittable fastball on the first pitch. Once the count reaches 0-1, the pitcher can attack with sliders, changeups, and breaking balls that leave the strike zone.
The first pitch often offers the cleanest opportunity.
MLB’s October 2025 analysis of game-opening plate appearances revealed how dramatically hitters have adjusted.
In 2010, leadoff batters swung at the first pitch of a game 12.1% of the time. By 2025, that figure had climbed to 28.2%.
Those percentages specifically describe the first pitch of the game, not every first pitch throughout nine innings. Still, the change demonstrates a clear shift in hitting philosophy.
Pitchers create part of that opportunity themselves.
During the 2025 season, starters opened games with a fastball 92.4% of the time. They also threw the first pitch of the game inside the strike zone at a 59.1% rate, compared with the league-wide zone rate of 50.7%.
Hitters weren’t imagining an advantage. They were recognizing a predictable situation.
The Count Changes Everything
A batter begins every plate appearance with several possible outcomes. He can take a ball, accept a strike, foul off a pitch, or put the baseball into play.
But those decisions don’t carry equal consequences.
Falling behind 0-1 gives the pitcher more freedom to expand the zone. Reaching 1-0 lets the hitter become more selective.
That creates a tension between patience and aggression.
A hitter who takes a borderline fastball might make an excellent decision. Another who watches a middle-middle heater could surrender the best pitch of his entire at-bat.
Real plate discipline isn’t simply about watching pitches pass. It requires recognizing location, movement, and velocity before committing to a swing.
Early-count swing percentages help reveal how often hitters choose aggression before the pitcher establishes control.
The harder question concerns which pitches deserve that aggression.
The 2022 Phillies and Padres Took Opposite Paths to October Offense
The 2022 National League Championship Series offered an early glimpse of baseball’s changing approach.
Philadelphia brought a lineup built around Bryce Harper, Kyle Schwarber, and Rhys Hoskins. Its hitters could turn one misplaced fastball into an enormous problem.
San Diego looked different. With Juan Soto anchoring a patient offensive philosophy, the Padres appeared more willing to work counts and force mistakes.
The contrast became obvious when the teams met in October.
Philadelphia hunted pitches early. San Diego generally showed greater restraint, particularly against fastballs.
FanGraphs analyst Ben Clemens examined those approaches in an October 25, 2022 report.
During the regular season, the Phillies swung at 43% of first-pitch fastballs inside the strike zone. The Padres attacked 45% of those same offerings.
Their behavior had been remarkably similar.
October changed the picture.
Across their first three postseason rounds, Philadelphia swung at 53.8% of first-pitch fastballs inside the strike zone. San Diego attacked just 39.9%.
That gap revealed two contrasting offensive plans.
Philadelphia Hunted Heat While San Diego Waited for Its Pitch
The Phillies entered at-bats prepared to punish fastballs. Their hitters often committed early rather than allowing pitchers to reach favorable counts.
San Diego preferred a narrower target.
The Padres swung at 48.9% of first-pitch breaking and offspeed offerings inside the zone. Philadelphia attacked 43.5% of those pitches.
So the supposedly patient Padres weren’t afraid to swing. They simply wanted different offerings.
San Diego also showed far more restraint against secondary pitches outside the strike zone.
The Phillies chased 28.6% of those first-pitch offerings. The Padres chased just 12.9%.
That difference mattered because pitchers could exploit Philadelphia’s willingness to expand its hitting area.
Yet the Phillies’ aggression created enormous damage when they connected.
During the postseason sample Clemens studied, Philadelphia batted .400 with an .844 slugging percentage on first pitches put into play.
San Diego hit .271 with a .576 slugging percentage in comparable situations.
Philadelphia eventually won the NLCS in five games, but those first-pitch results didn’t explain the entire series.
The Padres had created favorable counts through restraint. The Phillies generated more damage through aggressive contact.
Both approaches could work.
Early-count swing percentages mattered because they showed what each lineup was trying to accomplish, not because one number automatically identified the better offense.
The 2023 Rangers Turned First-Pitch Aggression Into a Championship Weapon
A year later, Texas took the aggressive approach even further.
The Rangers built an offense that could punish mistakes immediately. Seager, Marcus Semien, Adolis García, Josh Jung, and Leody Taveras all entered the 2023 postseason with a willingness to attack early.
Their approach wasn’t subtle.
In his October 27 World Series preview, Sports Illustrated’s Tom Verducci reported that Texas had five hitters among MLB’s top 49 in first-pitch swing rate.
Those five were Seager, Jung, Taveras, Semien, and García.
The results matched the aggression.
Entering the World Series, Texas had collected 26 hits in 65 at-bats completed on the first pitch during the postseason.
That produced a .400 batting average, the highest in baseball at that point. The Rangers also carried a .692 slugging percentage in those situations.
They weren’t taking early swings merely to keep pitchers uncomfortable.
They were doing damage.
Texas Accepted the Risk of Quick Outs
Aggression created a cost, and the Rangers understood it.
According to Verducci’s analysis, Texas made 495 one-pitch outs during the 2023 regular season. Baltimore ranked second with 432.
That was a striking difference.
A lineup built around traditional patience might have viewed those outs as unacceptable. Texas saw the other side of the bargain.
The Rangers finished the regular season with a .642 slugging percentage in at-bats completed on the first pitch, the fifth-best mark in baseball.
Sometimes the plan produced a first-pitch groundout. Other times, the same approach resulted in a baseball landing deep in the seats.
Texas didn’t allow one bad outcome to dictate the next plate appearance.
Veteran Arizona pitching coach Brent Strom recognized the problem before the World Series. Verducci’s reporting described how the Rangers could keep swinging early even after teammates made quick outs.
That willingness challenged conventional pitching strategy.
A pitcher might retire Semien on the first pitch and expect the next hitter to work deeper into the count. Seager could attack immediately anyway.
Texas refused to let previous outs change its intended targets.
Corey Seager Showed Why Aggression and Discipline Can Coexist
Seager became the clearest example of that philosophy.
During the 2023 regular season, he swung at 51.3% of first pitches. Lone Star Ball’s analysis of his approach also found that he put the ball into play on 20.3% of opening offerings.
Those weren’t the numbers of a hitter determined to see five pitches every trip.
But Seager wasn’t chasing everything.
An MLB.com analysis published on October 15, 2023, examined his swing decisions through Statcast’s different strike-zone regions.
During the regular season, Seager attacked 90.8% of pitches in the heart of the strike zone.
His swing rate on pitches clearly outside the zone, in Statcast’s chase region, was just 21%.
That difference revealed his actual offensive philosophy.
If a pitcher challenged him with a hittable strike, Seager almost always swung. When the baseball moved well outside the zone, he usually left it alone.
His early postseason numbers showed even sharper discipline.
Through the opening rounds covered by MLB’s report, Seager swung at 93.8% of pitches in the heart of the strike zone. His chase-region swing rate dropped to 14.3%.
He wasn’t abandoning patience.
He was using patience to make aggression more dangerous.
That distinction became unforgettable against Sewald in World Series Game 1.
The Arizona closer wanted his fastball above Seager’s barrel. Instead, the pitch entered a location Seager could drive.
The Rangers shortstop didn’t need another look.
He turned the mistake into a game-tying home run, and Texas eventually captured its first World Series championship.
One swing illustrated a philosophy that had powered the Rangers throughout October. But the success of that approach also exposed its weakness. Once pitchers recognize a hitter’s appetite for early strikes, they can stop feeding him the fastballs he wants.
The battle then shifts from who attacks first to who adjusts faster. Two seasons after Texas rode its aggressive approach to a title, one of baseball’s best pitchers found himself fighting that same battle from the mound.
Tarik Skubal Showed How Pitchers Fight Back Against the First-Pitch Ambush
By 2025, opponents had developed a clear plan against Detroit ace Tarik Skubal. They wanted to hit his fastball before he could bury them with his devastating secondary pitches.
Waiting too long against the left-hander could turn an at-bat into a miserable experience.
Hitters started attacking earlier.
A FanGraphs analysis by Lucas Kelly, published on August 8, 2025, documented the adjustment using Baseball Savant data.
In April, opponents swung at 37.3% of Skubal’s first pitches.
By May, that rate had reached 42.5%.
The spike revealed the league’s growing appetite for an early ambush. Opponents wanted to attack Skubal before he could unleash his full arsenal with the count in his favor.
The strategy generated some damage.
Batters recorded a .278 average and .778 slugging percentage in May at-bats that ended on the first pitch. During June, those figures climbed to .412 and .824.
Skubal had to change something.
Skubal Used His Changeup to Punish Hitters Hunting Fastballs
By July, the Detroit left-hander had adjusted his first-pitch approach.
He threw fewer opening pitches inside the strike zone and changed his pitch selection when he did attack it.
His changeup became especially important.
In June, changeups represented 10.2% of Skubal’s first pitches thrown inside the zone.
By July, that share reached 25%.
Hitters expecting a high-velocity fastball now had another possibility to consider.
A batter gearing up for 97 mph could find his swing moving too early when the changeup arrived.
The adjustment disrupted the timing that early-count attackers depend upon.
Opponents swung at 32.3% of Skubal’s first pitches in July. They also went hitless in the limited sample of at-bats completed on those pitches.
That doesn’t prove the changeup alone caused the improvement. Pitch location and sample size also matter.
Still, Skubal demonstrated the danger of becoming predictable.
Early-count swing percentages can expose a hitter’s intentions just as easily as they reveal a team’s offensive strategy.
When pitchers recognize the ambush, they can set a trap of their own.
The Numbers That Separate Smart Aggression From Reckless Swinging
A high early-count swing rate might look impressive on a scouting report.
It could also conceal a serious weakness.
A team that attacks strikes while refusing pitches outside the zone has an offensive advantage. A lineup swinging at everything gives pitchers more ways to escape trouble.
The distinction requires more than one statistic.
Chase Rate Reveals When a Hitter Loses the Zone
Consider Seager’s approach during the Rangers’ championship season.
He loved swinging at pitches in his preferred hitting areas. But he didn’t let pitchers drag him away from those locations.
A hitter facing an elevated fastball might prepare to attack. If the pitcher throws a slider diving below the knees, he has to recognize the difference.
Swinging at the slider doesn’t prove aggression. It might prove the pitcher fooled him.
Chase rate helps identify those mistakes.
Analysts should examine how frequently a team swings outside the zone alongside its willingness to attack strikes.
An aggressive offense with a low chase rate can be especially difficult to pitch against.
The hitter won’t give away a strike down the middle. He also won’t routinely rescue the pitcher by chasing a bad offering.
That’s the balance Texas achieved during its 2023 championship run.
Hard Contact Shows Whether the Plan Produces Damage
Swing decisions matter only when they create useful outcomes.
Statcast measures exit velocity, launch angle, and barrel rate to help explain what happens after contact.
Those measurements can separate productive aggression from empty swings.
A hitter might attack first-pitch fastballs frequently but produce little more than weak grounders. Another could swing less often and punish nearly every mistake.
Their raw swing percentages would tell only part of the story.
Barrel rate offers another piece of evidence. It identifies batted balls struck with particularly productive combinations of exit velocity and launch angle.
Analysts can also examine expected weighted on-base average to evaluate contact quality and other offensive outcomes.
For an MLB coaching staff, those numbers help answer a practical question.
Is the hitter finding pitches he can drive, or is he swinging because the scouting report told him to attack early?
The difference can determine whether a lineup keeps its approach or changes it before the next series.
The Dugout Scouting Report Now Starts Before Pitch One
Modern hitters have access to more detailed pitching information than previous generations could have imagined.
Before stepping into the box, they can examine where a pitcher locates his fastball, which breaking pitch he favors against each handedness, and how frequently he attacks the zone on 0-0 counts.
Coaches can compare those tendencies with a hitter’s preferred contact locations.
The preparation allows players to enter an at-bat searching for something specific.
But the information still has limits.
A scouting report might reveal that a pitcher usually starts right-handed hitters with a four-seamer. It cannot guarantee that he’ll follow the same pattern in October.
Seager’s World Series home run illustrated the value of preparation. Skubal’s 2025 adjustment revealed why hitters must remain flexible.
Both sides study the same confrontation.
Bat Tracking Is Adding Another Layer to Offensive Preparation
Statcast expanded its bat-tracking measurements in 2024, giving teams more information about swing speed, swing length, and how efficiently hitters square up the baseball.
Those metrics can help explain why two hitters react differently to similar pitches.
One hitter might consistently catch up to an early-count fastball because his swing reaches the hitting zone quickly. Another could struggle with the same velocity despite recognizing the pitch correctly.
Coaches can examine whether a hitter’s aggressive approach matches the pitches he handles best.
The technology also creates opportunities for more individualized preparation.
A team might instruct one player to hunt first-pitch fastballs while encouraging another to wait for something lower in the zone.
Those instructions can coexist within the same lineup.
Early-count swing percentages then become a window into several offensive plans working together, rather than one rule applied to every hitter.
The numbers matter most when analysts connect them to actual swing decisions.
The Next First Pitch Will Reveal Who Prepared Better
The next stage of offensive strategy won’t necessarily involve swinging more often.
It will involve recognizing better opportunities.
The 2022 Phillies demonstrated how a lineup could embrace early fastballs and generate enormous damage. San Diego showed that a more selective approach could also produce favorable results.
A year later, the Rangers took first-pitch aggression to the World Series.
Texas didn’t win simply because its hitters swung early. The club succeeded because players such as Seager attacked strikes they could drive while avoiding pitches designed to lure them outside the zone.
That distinction separated a dangerous offensive plan from a careless one.
Skubal’s 2025 adjustments supplied the next warning. Once pitchers recognize an aggressive tendency, they can alter their sequences and challenge hitters to make another adjustment.
Baseball’s tactical battle never ends with one successful approach.
Modern tracking systems will continue giving teams better information about pitch selection, bat speed, contact quality, and individual hitting zones.
But the most valuable information still depends on execution.
A hitter can memorize every first-pitch tendency in a scouting report. He still has to recognize the baseball traveling toward him at major-league speed.
Early-count swing percentages offer a way to understand those choices. They show whether a lineup prefers to attack immediately, wait for a particular offering, or change its approach against different opponents.
The statistic becomes most revealing when teams explain it through the pitches they actually swing at.
Seager’s home run against Sewald remains a perfect illustration.
Arizona needed two outs. Texas needed a mistake. Sewald tried to elevate his fastball, and Seager recognized an opportunity before the crowd could fully appreciate the danger.
The ball traveled 418 feet.
That swing didn’t prove taking the first pitch was wrong. It proved that a hitter who knows what he wants should never surrender the pitch simply because it arrives early.
The best offenses don’t swing at everything. They make pitchers regret the strikes they throw.

FAQs
Q1. What are early-count swing percentages in baseball?
Early-count swing percentages show how often hitters swing at pitches early in an at-bat. They help reveal whether an offense prefers aggression or patience.
Q2. Why do MLB hitters attack the first pitch?
Hitters often expect an early fastball in the strike zone. Attacking that pitch can prevent pitchers from gaining control of the count.
Q3. Why was Corey Seager so effective at hitting early pitches?
Seager attacked hittable strikes while avoiding pitches outside his preferred zone. That combination made his aggressive approach especially dangerous.
Q4. Does swinging at the first pitch improve offensive production?
Not automatically. Hitters need to recognize good pitches and make hard contact. Swinging early without discipline can produce quick outs.
Q5. How do pitchers stop aggressive first-pitch hitters?
Pitchers can change their opening pitch selection, location, or speed. Tarik Skubal used his changeup more often to disrupt hitters expecting fastballs.
