Jacob Misiorowski Throws the Four Fastest Pitches Ever Tracked From a Starting Pitcher — and the Yankees Couldn't Touch Him

Jacob Misiorowski didn't ease into his first career start against the Yankees. The 24-year-old Brewers right-hander walked out to the mound at American Family Field on Friday night and threw the four fastest fastballs ever recorded by a starting pitcher since pitch tracking began in 2008 — topping out at 103.6 mph on the pitch that got Aaron Judge to line out and end the first inning. As MLB.com reported, Misiorowski struck out Trent Grisham and Ben Rice on three pitches each, hitting 102.8 and 103.3 mph respectively on the decisive strike threes, before going 0-2 on the reigning AL MVP with four straight triple-digit fastballs. Judge made contact on the fifth — and still went quietly to right field.

What makes this performance extraordinary isn't just the raw velocity — it's the context. Misiorowski threw eight consecutive four-seam fastballs to open the game, and New York's lineup, one of the most dangerous in the American League, had no answer. He was nearly immaculate in the first: three up, three down, two strikeouts, nine pitches. Then he kept going. In the second inning, facing Yankees outfield prospect Spencer Jones making his MLB debut, Misiorowski registered two more pitches at 103.6 mph before Jones foul-tipped into a strikeout. Two innings, two scoreless frames, and a radar gun reading that belongs in a physics classroom.

The velocity pattern here is worth noting for projection purposes. Misiorowski typically operates at peak velocity early and fades as pitch count climbs — a profile common to young power arms still building starter stamina. But against New York, his second inning was matching, not trailing, his first. That's either an adrenaline-fueled outlier or a sign that his stuff is maturing into something more durable. Either way, facing the Yankees for the first time, on a big stage, the arm was absolutely live.

For bettors, this performance recalibrates how seriously to take Misiorowski's strikeout lines every time he takes the ball. A starter who can hold 103-plus into the second inning against a lineup of Judge, Rice, and Jones is generating genuine chase-rate stress at the top of the zone — the kind of velocity that turns borderline fastballs into swings and misses. His K prop deserves a hard look each outing, particularly in the early innings when his velo is at its ceiling. The Brewers team total also warrants attention in Misiorowski starts: a pitcher this dominant early suppresses scoring windows and keeps Milwaukee in low-run-environment games, making unders on first-five-inning totals a recurring angle worth tracking.

The Yankees' inability to do anything productive against pure heat — and a lineup that includes Judge, one of the best fastball hitters alive — also raises a short-term red flag on New York's offensive props in this series. If Misiorowski is operating above 103 mph and living exclusively on the fastball without consequence, the under on the Yankees team total is the cleanest number in Milwaukee this weekend.
