A pitch clocked at 105.5 mph and a probability line climbing toward 70% are telling the same story this week.
On Polymarket's "MLB: Strikeouts Leader – Pitcher", Milwaukee Brewers right-hander Jacob Misiorowski jumped 20 percentage points in a single day, reaching 70% and pulling well clear of Philadelphia's Cristopher Sanchez, who sits at 22%. San Diego's Dylan Cease and Pittsburgh's Paul Skenes trail far behind, each holding around 4-5% of the market.
The move didn't come out of nowhere.
Misiorowski, 24, enters July with a 9-3 record, a 1.45 ERA and 146 strikeouts across 99 innings, all tops among Major League starters. His June alone included a stretch where he posted a 0.96 ERA and struck out 38 hitters in just 28 innings over four starts, numbers that read more like a highlight reel than a monthly stat line.
Why the Market Is Moving Toward Misiorowski
Misiorowski's fastball is doing most of the talking.
Facing the Chicago Cubs on June 26, he uncorked a 105.5 mph heater to center fielder Pete Crow-Armstrong, the hardest pitch thrown by a starter since Statcast began tracking velocity in 2008. Only left-handed reliever Aroldis Chapman has topped that mark, and only in relief appearances back in 2010 and 2016. Reliever Ben Joyce matched the exact figure, 105.5 mph, in 2024.
Asked afterward whether hitting 108 mph is realistic, Misiorowski didn't hesitate: "I definitely think it's possible," he told ESPN. "Science says you can hit 108. Someone eventually is going to hit it. If that's me, cool. I don't think that's something I need to focus on."
Two weeks earlier, against Philadelphia, he'd already put together one of the more remarkable pitching lines in the Phillies' long history: 15 strikeouts and a single hit allowed over nine innings in a 6-0 shutout.
Only three other pitchers have matched that exact combination against Philadelphia since the franchise's founding in 1883: Warren Spahn, Nolan Ryan and Tom Seaver, each doing it decades before Misiorowski was born.
Sanchez Cools Off as the Gap Widens
Sanchez (10-3, 2.00 ERA) has no intention of letting Misiorowski run away with the narrative.
He still commands all of MLB with a 5.2 bWAR and trails only Misiorowski in fWAR (3.9). While that three-start rough patch, where he allowed 10 earned runs over 16.2 innings, perfectly aligned with the stretch in which Misiorowski's market share took off, Sanchez emphatically halted the slide on Tuesday night. Now sitting at 10-3 with a 2.00 ERA, his resilience suggests that while traders heavily weighed his brief slump, the actual gap in this race remains on.
Cease and Skenes remain mathematically in the picture, but neither has produced the kind of standout outing currently working in Misiorowski's favor, and closing a gap this wide with half a season left would take a real shift in form from one side or the other.
With the All-Star break approaching and both aces likely to start once more before it, the strikeouts race still has plenty of runway left to play out. For now, though, the radar gun and the probability chart are pointing in the same direction, and it will take something unusual to bend either one back the other way.
