The high-velocity sinker faced its biggest October test at Dodger Stadium on October 15. Milwaukee held a fragile 5-4 lead when Aaron Ashby took over in the seventh inning, needing nine outs to finish off the defending champion Dodgers. One bad pitch could have sent the National League Championship Series toward another game.
Los Angeles had already shown its teeth. Shohei Ohtani’s three-run homer helped build an early 4-0 lead, shaking a stadium that desperately wanted the Dodgers’ season to continue. Now Ohtani and Mookie Betts loomed near the top of the order, waiting for another mistake.
Ashby brought a different kind of trouble. His sinker averaged 97.7 mph during the regular season, and his breaking balls gave hitters little room to anticipate what came next. With his season’s biggest assignment underway, the left-hander trusted the same weapons that had carried Milwaukee’s bullpen through October.
Three scoreless innings later, the Brewers owned a 6-4 victory and their first World Series berth since 1982. Ashby had survived two serious scoring threats without allowing a run.
The high-velocity sinker helped make that possible. A pitch baseball nearly abandoned during the launch-angle revolution had returned with more speed, sharper movement, and a different purpose.
How launch-angle hitting nearly killed the sinker
Baseball spent much of the 2010s turning an old pitching commandment upside down. For generations, coaches told pitchers to keep fastballs low and force hitters into ground balls. Then the launch-angle revolution taught batters to hunt those same pitches and lift them.
Josh Donaldson, Brandon Moss, and Josh Reddick helped demonstrate the approach with Oakland. Their powerful swings punished pitchers who kept feeding them fastballs near the knees. A 90-mph sinker no longer looked particularly threatening when a hitter could match its downward path with an ascending barrel.
By 2025, the pitch had become a shadow of its former self. MLB.com’s Mike Petriello found that sinkers accounted for only 15% of pitches, their lowest share since tracking began in 2008. Yet the sinkers that survived were doing more damage than ever before. Pitchers had abandoned weaker versions and rebuilt the rest.
Watch Abner Uribe bring 99 mph toward a right-handed hitter’s knuckles, and the transformation becomes clear. Petriello’s Statcast research showed that just 9% of sinkers topped 95 mph in 2010. By early 2025, that figure had climbed to 31%. The old pitch had gained enough velocity to challenge hitters who once feasted on low fastballs.
Movement changed alongside the speed. Back in 2010, 53% of sinkers generated more than 14 inches of arm-side break. Fifteen years later, that share had reached 73%. Pitchers were no longer relying on the ball simply dropping toward the bottom of the zone. They could run it sideways, crowd the hands, and make powerful hitters uncomfortable.
The high-velocity sinker had become a different weapon.
The power sinker now attacks the hands instead of the dirt
Modern pitchers have changed more than the baseball’s flight path. They’ve reconsidered where to throw it and which hitters should face it.
Petriello’s research found that right-handed pitchers directed 70% of their sinkers toward right-handed batters in early 2025, compared with 47% in 2013. Uribe shows why. His sinker can run sharply toward a righty’s hands, forcing an abbreviated swing or uncomfortable contact near the handle.
A decade ago, pitchers frequently aimed for the lower middle of the strike zone. Now they attack the inner half, where a hitter has far less room to extend the barrel. Add elite velocity, and even a correctly anticipated fastball becomes difficult to square.
The change also gives pitchers more freedom with their secondary pitches. When Uribe threatens the hands with a sinker, his upper-80s slider can move away from the same hitter. The batter must protect the inside corner without losing track of a breaking ball heading toward the opposite edge.
That’s a brutal assignment with two strikes.
Pitchers can use the high-velocity sinker to take away the comfortable swing path that launch-angle hitters spend countless hours refining. Those few inches of movement can decide whether the barrel finds the ball cleanly or sends a weak grounder toward second base.
Milwaukee’s bullpen has turned the sinker into an October weapon
The Brewers have embraced that approach with a relief corps built around contrasting movement profiles. Trevor Megill supplies another high-velocity option, while Abner Uribe and Aaron Ashby demonstrate how the sinker can dominate without depending entirely on strikeouts.
Their pitching styles differ, but both force hitters into uncomfortable decisions late in games. Milwaukee doesn’t need every pitch to miss the bat. Sometimes the ideal outcome is a hurried grounder toward an infielder.
Abner Uribe makes 99 mph feel even faster
Uribe doesn’t need a complicated sequence to get a hitter’s attention. His sinker averaged approximately 99 mph during the 2026 regular season, arriving with enough movement to make a clean swing difficult.
According to MLB.com’s October analysis, Uribe generated a 54.6% ground-ball rate, placing him in the 93rd percentile among qualified pitchers. Opponents barreled just 2% of their batted balls against him, a mark that ranked in the 99th percentile.
Hitters rarely square up his best stuff, even when they manage to put it in play. His relatively low arm angle gives the sinker a difficult trajectory, while the upper-80s slider forces batters to cover a different part of the plate.
A right-handed batter must protect against a 99-mph sinker running toward the fists while remaining alert for a breaking ball moving away from the barrel. Wait too long, and the fastball beats the swing. Commit too early, and the slider can disappear beyond the outside corner.
Uribe controls an entire at-bat with that combination. Hitters begin defending against two pitches before they’ve seen either one.
Aaron Ashby offers a different kind of punishment
Ashby attacks from the left side, but his sinker carries similar power. At 97.7 mph, the pitch ranked among the fastest sinkers thrown by left-handed pitchers in 2026.
His background as a starter gives him more options than the conventional two-pitch reliever. Milwaukee can turn to his curveball, slider, or changeup whenever a hitter begins anticipating the fastball.
Statcast recorded a remarkable 56.6% whiff rate on Ashby’s slider during the regular season. His curveball generated a 52.4% whiff rate, while his changeup produced a 48.9% mark. Very few pitchers could threaten hitters with three secondary pitches capable of missing bats at those rates.
Against a right-handed hitter, Ashby’s hard sinker can run toward the outer portion of the plate. His curveball drops sharply, while the changeup resembles the fastball before arriving at a slower speed.
A batter sitting on the sinker may swing too early against the breaking ball. Someone waiting for the slower pitch risks watching a 98-mph fastball beat the barrel to the plate.
Ashby carried that arsenal into the NLCS, where Milwaukee needed every out he could provide.
Nine outs from the World Series, Ashby refused to blink
Andy Pages opened the seventh inning of Game 4 with a double, immediately putting Milwaukee’s one-run lead in danger. Kiké Hernández sacrificed Pages to third, bringing Ohtani to the plate with the tying run 90 feet away.
The crowd could see the opportunity. Ohtani had already punished Milwaukee with a three-run homer, and another well-struck ball might have changed the series.
Ashby struck him out.
Betts followed with the chance to bring Pages home, but the Brewers’ left-hander forced a groundout to escape. Two of baseball’s biggest names had come up with the tying run at third, and neither delivered the hit Los Angeles needed.
The eighth brought another crisis.
Will Smith stepped into the box against an Ashby fastball approaching triple digits. The Dodgers catcher didn’t flinch, driving a 99.8-mph sinker into right field for a double.
Statcast measured the contact at 95.3 mph off the bat with a 13-degree launch angle. Smith caught the fastball cleanly and sent it into the gap, proving that even exceptional velocity couldn’t always beat a well-timed swing.
A fielding error by Sal Frelick allowed Smith to advance to third. Milwaukee once again faced the possibility of watching its lead disappear.
Kyle Tucker lifted a shallow fly ball to center. Teoscar Hernández then struck out, leaving Smith stranded and sending the Brewers into the ninth inning still ahead 5-4.
David Hamilton added an insurance homer before Ashby returned for the final three outs. His last pitch produced a line drive from Kiké Hernández that Jackson Chourio caught in left field.
Milwaukee had finally done it.
Ashby completed three scoreless innings with two hits, three strikeouts, and no walks, protecting the Brewers’ first pennant in 44 years. His sinker had helped carry them through one of the toughest stretches of their postseason.
Why launch-angle hitters still struggle against late movement
Smith’s double exposed the sinker’s limits. It also revealed what makes the pitch so difficult to handle consistently.
Modern hitters build their swings around matching the barrel to the baseball’s path. The launch-angle revolution encouraged batters to produce more line drives and fly balls rather than settling for grounders. Statcast identifies the productive launch-angle sweet spot as 8 to 32 degrees.
A sinking fastball challenges that geometry.
When a hitter expects a straighter pitch, the barrel can arrive above the baseball’s final location. Instead of lifting the ball into the gap, he catches its upper half and pounds a grounder toward shortstop.
The opposite mistake can hurt just as much. A sinker running toward the hands may jam a batter before he can extend his arms. Even a powerful swing loses much of its force when contact occurs near the handle.
Milwaukee’s relievers exploit those narrow margins. Uribe’s hard sinker challenges hitters inside, while his slider forces them to protect the outside corner. Ashby can change speeds more dramatically, using his breaking pitches to punish anyone who begins sitting on the fastball.
The high-velocity sinker becomes especially valuable with runners aboard. A ground ball can erase a scoring threat through a double play, while a weakly hit roller may keep a runner from advancing.
The strategy still demands precise command. A sinker that drifts toward the middle of the plate can turn into a dangerous mistake, particularly against hitters with enough bat speed to adjust.
Smith proved that against Ashby. Even 99.8 mph couldn’t prevent a damaging swing when the pitch met the barrel at the right angle.
The sinker’s comeback doesn’t mean launch-angle hitting stopped working. Pitchers found another way to make the ideal swing harder to produce.
Tampa Bay brings dangerous contact into the World Series
Milwaukee’s next opponent offers a tougher test of that formula.
The Brewers host the Tampa Bay Rays in Game 1 of the World Series on October 23, facing a lineup that combines dangerous power with an exceptional ability to put the bat on the ball.
Junior Caminero and Yandy Díaz each homered during Tampa Bay’s 7-3 ALCS-clinching victory over Cleveland. Both have punished sinkers throughout the season, and neither presents a matchup Milwaukee’s relievers can approach casually.
Baseball Savant’s 2026 data shows that Rays hitters made contact on approximately 67% of swings at pitches outside the strike zone, compared with a league average near 57%. Tampa Bay also recorded a 20.7% whiff rate, well below the MLB average of 25.1%.
The Rays don’t necessarily chase fewer pitches than everyone else. Their team chase rate of 30.7% sat close to the league average of 30.5%. But they connect with difficult offerings that other hitters often miss. MLB.com’s examination of Tampa Bay’s contact-oriented offense also showed that its whiff rate had fallen from 25.7% in 2025 to 20.7% in 2026.
Uribe can throw a sinker that runs off the inner edge, only to watch a hitter fight it into foul territory. Ashby might bury a breaking ball beneath the zone and still find the batter extending an arm to stay alive.
For power pitchers accustomed to finishing at-bats quickly, those extra swings can become exhausting.
Yandy Díaz can turn elite velocity into a long at-bat
Díaz represents the more disciplined contact threat.
During the 2026 regular season, he chased only 29% of pitches outside the strike zone and produced a 14.8% whiff rate. His 77.5% chase-contact rate showed how frequently he connected even when pitchers moved the ball beyond the plate.
His performance against sinkers adds another complication. Díaz hit .308 with a .391 slugging percentage against the pitch classification, missing on just 6.6% of his swings.
Uribe may fire a 99-mph sinker toward the hands, expecting an uncomfortable swing. Díaz can spoil the pitch, refuse to chase the next breaking ball, and force the reliever to return with another strike.
The at-bat becomes a contest of patience against power. Milwaukee wants an immediate decision, while Díaz can keep searching for a pitch he can drive.
Junior Caminero can punish the pitch Milwaukee trusts most
Caminero creates a different kind of danger.
The young slugger hit .347 with a .597 slugging percentage against sinkers in the regular-season Statcast data. He also generated a 56.8% hard-hit rate against the pitch, showing that his success came from consistently punishing mistakes rather than simply finding holes in the defense.
Caminero isn’t quite as difficult to fool as Díaz. His overall 24.1% whiff rate and 30.5% chase rate sat near league averages, but he showed more restraint against first pitches than the typical major leaguer. Statcast recorded a 24.7% first-pitch swing rate for him, compared with the MLB average of 32.3%.
Milwaukee cannot count on an impatient first swing. Caminero can work into a favorable count, wait for the sinker to drift over the plate, and use his bat speed to send it toward the left-field seats.
The Brewers will need to move the fastball carefully, avoid predictable locations, and trust their secondary pitches when the count turns unfavorable.
The World Series may decide who wins the battle of inches
Milwaukee’s bullpen enters the World Series with a clear identity. Uribe can overwhelm hitters with 99-mph movement, while Ashby offers a hard sinker supported by three dangerous secondary pitches. Together, they give Pat Murphy multiple ways to attack a lineup without depending entirely on elevated four-seam fastballs.
Tampa Bay presents the opposite challenge. Díaz rarely gives away an at-bat, and Caminero has enough raw power to punish a sinker that catches too much plate. The Rays’ exceptional contact numbers suggest that Milwaukee may need more pitches than usual to finish important hitters.
An eight-pitch showdown with Díaz might seem harmless in the seventh inning, but repeated battles can quickly increase a reliever’s workload. Caminero adds pressure because one misplaced fastball can undo several innings of careful pitching.
Milwaukee must choose how aggressively to attack the strike zone. Too many pitches outside it will allow patient hitters to work into favorable counts. Too much predictability inside it could give Tampa Bay’s power bats an opportunity to square up elite velocity.
The high-velocity sinker remains a crucial weapon because it can generate weak contact without sacrificing speed. A well-placed pitch can jam Díaz or force Caminero into a harmless grounder. Miss the intended spot by a few inches, and the same fastball could become the swing that changes the World Series.
Baseball’s launch-angle revolution made low fastballs dangerous, prompting pitchers to find new ways to beat rising barrels. The modern power sinker has answered with more velocity, sharper movement, and an aggressive approach to the inner half of the plate.
Now the hitters get another chance to adjust.
Come Friday night, the decisive swing may not launch a baseball into the upper deck. It could be the one that misses the barrel by an inch and sends another 99-mph sinker rolling toward shortstop.
Or Tampa Bay might catch that same pitch cleanly and remind Milwaukee why the sinker disappeared in the first place.
