Jacob Misiorowski facts: the Brewers pitcher’s fast rise

Jacob Misiorowski facts start with a pitcher built for attention and numbers. Born in Blue Springs, Missouri, on April 3, 2002, the Brewers right-hander is known by the nickname “the Miz,” and his early career moved quickly once the radar gun and the box score started lining up.

From Blue Springs to Milwaukee

Jacob Misiorowski facts before the majors begin at Grain Valley High School and Crowder College. As a junior at Grain Valley in 2019, he went 9–2 with a 1.48 ERA and earned All-State honors. His senior season in 2020 was canceled because of COVID-19, so his next big stretch came at Crowder College in 2022, where he went 10–0 with a 2.72 ERA and 136 strikeouts in 76 innings pitched.

That performance led to the next step. The Milwaukee Brewers selected Misiorowski 63rd overall in the 2022 Major League Baseball draft, and he signed with the club on July 27, 2022, for a $2.35 million over-slot bonus. By then, the climb from Missouri standout to pro arm was already well underway.

How did Jacob Misiorowski reach the majors so fast?

Jacob Misiorowski reached the majors through a short, forceful minor league path that ended with a debut in 2025. On June 12, 2025, he made his MLB debut and threw five no-hit innings while earning the win. In his second MLB start, he threw six perfect innings, and that gave him 11 no-hit innings to open his career, the first MLB player to do that since 1961.

The Brewers rewarded that start to his big-league career with a major honor. Misiorowski was named to the National League All-Star roster in 2025 after just five major league games. That same season he moved from a debuting arm to an All-Star selection in a hurry, all in the span of a few games.

What made 2026 a record-setting season?

Jacob Misiorowski’s 2026 season turned into a history book of velocity and volume. He was named the Brewers’ Opening Day starter and became the youngest Brewers pitcher to start on Opening Day since Ben Sheets in 2002. On June 12, 2026, he completed a Maddux with a one-hit shutout on 95 pitches and 15 strikeouts.

The headline-grabbing numbers kept coming. In 2026, Misiorowski set the record for the fastest pitch thrown by a starting pitcher since tracking began in 2008. Then, on September 8, 2026, he became the first pitcher in MLB history to throw 1,000 pitches 100+ mph in one season. By the end of that year, he had finished 16–5 with an MLB-leading 252 strikeouts.

Why do baseball fans keep circling the name “the Miz”?

Jacob Misiorowski facts are easy to connect to the nickname “the Miz” because so many of his milestones are tied to numbers that jump off the page. The fast start in 2025, the All-Star nod after only five major league games, the 11 no-hit innings to begin a career, and the 2026 velocity records all fit together as one short but packed arc.

His path also has clear checkpoints: Blue Springs, Grain Valley High School, Crowder College, the 2022 draft, a $2.35 million signing bonus, then the big-league leap in 2025 and the record-setting follow-up in 2026. Each step is marked by a date, an inning total, or a strikeout count.
