Jacob Misiorowski closed the 2026 regular season as the best pitcher in the National League — 1.80 ERA, 252 strikeouts, 0.80 WHIP, leading MLB in all four categories that matter. But there’s one opponent that gives him trouble in every road stadium: the mound clay. Not his arm, not his head — the problem is that he’s 6-foot-7 and his landing foot hits ground that no visiting groundskeeping crew ever thought to prepare.
A stride that goes further than anyone else’s
When a pitcher releases the ball, the landing foot drives toward home plate. How far it travels depends on height, mechanics and how aggressively a pitcher attacks the rubber. For most guys, that landing spot falls well within the zone the home team conditions and repairs between innings. Misiorowski doesn’t land in that zone. His 6-foot-7 frame produces one of the longest strides in the big leagues, dropping his foot several inches beyond where any home groundskeeping crew anticipated. The result: dry, hard, unmaintained clay right where he needs the most support.
It’s not a minor inconvenience — it’s a real injury risk
On August 2, 2026, at Angel Stadium, Misiorowski stopped play two or three times to ask the grounds crew to fix the mound. The same thing happened on October 28 at Tropicana Field during Game 5 of the World Series: he requested repairs before every half-inning he pitched, and slipped on a warmup pitch before the second inning.
When the media asked if the mound explained the loss to the Angels, Misiorowski was blunt: «You can’t blame that. I have to do my job.» And his numbers backed him up — that night he struck out 10 in 7 innings on just 83 pitches, allowing 2 hits and 2 runs. The loss came from a lack of offense, not from the pitcher.
Still, Statcast picked up something worth noting: his average fastball velocity dropped 1 mph that game, and his slider fell 2.1 mph below his season average. Small numbers on paper — but on a pitcher whose fastball averages 99.7 mph during the regular season and hit 101.2 mph on average in the postseason, that dip means something. Instability at the landing foot disrupts the entire kinematic chain of a delivery.
The pattern became harder to ignore in October. At American Family Field, the mound is dialed in for him. At Petco Park, Dodger Stadium, Tropicana Field — every road venue — the grounds crew works for the average pitcher. Misiorowski is not the average pitcher, not in height, not in mechanics.
A record nobody had seen before — which makes the stakes higher
On September 8, 2026, Misiorowski became the first pitcher in MLB history to throw 1,000 pitches at 100+ mph in a single season. More than 60% of his regular-season pitches topped 100 mph. There is no direct comparison for what he does in the current game.
That’s exactly why the injury risk carries more weight, not less. An average pitcher who slips on the mound loses his footing and maybe gives up a hit. Misiorowski generates that level of force and velocity on every single pitch. A slip at the wrong moment could cost the Brewers something they absolutely cannot afford to lose.
Milwaukee won the 2026 World Series in five games over the Tampa Bay Rays, with Misiorowski as the centerpiece. The mound issue didn’t stop him this year. But the pattern — August in Anaheim, October in St. Petersburg — is documented and recurring. The question heading into 2027 is whether any road team’s groundskeeping crew will take note before something actually goes wrong.
