Jacob Misiorowski of the Milwaukee Brewers delivered a performance for the ages on Friday, hurling a 105 mph fastball—the fastest ever recorded from a starter—and piling up 15 strikeouts in a nine‑inning, one‑hit shutout against the Philadelphia Phillies. the right‑hander’s line of 15 K, one hit, zero walks and zero runs on 95 pitches cemented the game as one of the most dominant starts in modern MLB history.

105 mph Fastball Sets New Starter Benchmark

Misiorowski opened the game by striking out MLB home‑run leader Kyle Schwarber on a 2‑2 count with a pitch measured at 105 mph on broadcast, according to the game report. That velocity eclipses every previous starter’s record and narrows the gap with Boston Red Sox closer Aroldis Chapman’s all‑time high of 105.8 mph.

He followed with a first‑inning side‑strikeout, fanning Trea Turner on four pitches and Bryce Harper on three, while his slowest fastball that inning still sat at 102.3 mph. in total, Misiorowski threw 58 pitches clocked at 100 mph or higher and averaged an astonishing 101.7 mph for the night.

15‑Strikeout Maddux on 95 Pitches

The Brewers ace faced the minimum 27 batters, allowing only a single in the fourth inning that was erased by a double play. His 15‑strikeout, sub‑100‑pitch shutout—known as a “Maddux”—has never been achieved with such velocity, making the feat unprecedented in MLB annals.

Philadelphia hitters swung 41 times at his fastball, missing 24 times for a 59% whiff rate, a statistic highlighted by the source. The dominance was complete: zero walks, zero runs, and a flawless 1.34 ERA that now tops all qualified starters.

Cy Young Conversation Intensifies

Misiorowski’s season numbers have propelled him into serious Cy Young award talk, alongside Los Angeles Dodgers two‑way phenom Shohei Ohtani and Phillies ace Cristopher Sánchez, as noted by the report.. His ability to combine record‑setting velocity with pinpoint control disinguishes him from peers who rely more on movement than sheer speed.

While Chapman still holds the overall fastest pitch record, Misiorowski’s 105 mph outing proves that starters can now challenge relievers for the upper‑hand in raw speed, a development that could reshape scouting priorities.

Who Will Challenge Misiorowski’s Record?

The next question on fans’ minds is whether any other starter can match or exceed the 105 mph mark in a regular start. as of now, the source provides no indication of another pitcher approaching that threshold, leaving Misiorowski’s record untested.

Additionally, analysts will watch how the Brewers manage his workload after such a high‑velocity outing, given the historical link between extreme fastball speeds and arm fatigue.
