Jacob Misiorowski Wiki, Age, Height, Net Worth 2026

Jacob Misiorowski — “The Miz” — is an American professional baseball pitcher for the Milwaukee Brewers Born on 3 April 2002, the 24-year-old led the majors in ERA (1.80), strikeouts (252) and WHIP in 2026 while throwing the hardest average fastball of any starting pitcher, he started Game 1 of the 2026 World Series against Tampa Bay on 23 October 2026. His first pitch of the Fall Classic — a 103.5 mph fastball to Yandy Diaz, per MLB’s Statcast — was the fastest ever by a starting pitcher in a World Series game. Behind him in center field stands Garrett Mitchell, whose own October heroics defined the Brewers’ run.

Early Life

Jacob Walter Misiorowski was born on 3 April 2002 in Blue Springs, Missouri, according to Baseball-Reference. He went undrafted out of Grain Valley High School in Missouri. At Crowder College in Neosho, Missouri, his velocity exploded. Heavy.com, citing Sports Illustrated’s Tom Verducci, reports that Misiorowski first touched 100 mph at the 2022 Junior College World Series. The Baseball Cube records his junior-college dominance: a 10–0 record with 136 strikeouts and a 2.76 ERA in 76 innings across 15 starts.

The 6-foot-7 right-hander piqued scouts’ interest despite playing at a less-heralded school, and the Milwaukee Brewers selected him in the second round (63rd overall) of the 2022 MLB Draft, per Baseball-Reference’s BR Bullpen. Heavy.com reports that he signed for $2.35 million — an above-slot bonus the Brewers paid to keep him from pursuing Division I baseball.

Career

Misiorowski moved steadily through the Brewers’ farm system. Per Baseball-Reference’s BR Bullpen, he split 2023 across three levels — Carolina, the Wisconsin Timber Rattlers and Double-A Biloxi — going 4–2 with a 3.41 ERA and 110 strikeouts in 71 1/3 innings, earning a spot in the 2023 All-Star Futures Game. In 2024 he split time between Biloxi and Triple-A Nashville, striking out 127 batters in 97 1/3 innings while sitting 97 mph and above with his fastball.

His big-league arrival was historic. He debuted on 12 June 2025 against the St. Louis Cardinals, allowing no hits over five innings, and pitched so well over his first five starts that he was controversially chosen as an All-Star replacement. He finished 2025 with a 5–3 record and a 4.36 ERA with 87 strikeouts in 66 innings.

Then came 2026: a full-season masterpiece. Per USA Today and the Associated Press, Misiorowski went 16–5 across 30 starts, leading the majors in ERA (1.80), strikeouts (252) and WHIP (0.802). His four-seam fastball averaged 100.6 mph — the highest among all starting pitchers, per Statcast via Bleacher Report. He threw 1,115 pitches at 100 mph or higher, shattering Jordan Hicks’ mark of 673, per the AP, and hit 105.5 mph against the Cubs’ Pete Crow-Armstrong on 27 June — just shy of Aroldis Chapman’s regular-season record of 105.8. The Baseball Cube notes he was the Brewers’ Opening Day starter in 2026.

In the 2026 postseason, high pitch counts kept him from finishing five innings in his first two starts — 88 pitches over four frames in NLDS Game 1 against San Diego, then 94 pitches for 4 1/3 in NLCS Game 1 against the Dodgers, a series the Brewers swept, per USA Today. In Game 1 on 23 October 2026 at American Family Field, he went five innings, allowing one run on four hits with three strikeouts — 37 of his 78 pitches at 100 mph or faster, per USA Today. The Associated Press confirmed his opening 103.5 mph fastball broke the World Series record for a starting pitcher (the old starter record was Noah Syndergaard’s 101.1 mph in 2015; Chapman’s 103.2 mph in 2016 was thrown in relief), while USA Today noted the pitch was taken for a ball above the strike zone — a historic first pitch regardless.

Personal Life

Jacob Misiorowski keeps his personal life largely private and has not publicly confirmed details about a partner or family. Sports Illustrated’s Tom Verducci reported he added close to 30 pounds over the winter before 2026 — mostly in his legs. His Instagram handle is @jmisiorowski, per Baseball-Reference. Baseball-Reference lists his nickname officially: “The Miz” — a handle that stuck as his triple-digit fastball became appointment viewing.

Jacob Misiorowski Net Worth 2026

Jacob Misiorowski’s net worth has not been officially disclosed, and no credible published estimate exists. His earnings, however, are a matter of public record: Spotrac reports a $2.35 million signing bonus in 2022, a prorated $445,376 salary for his 2025 debut season, and a $788,300 salary for 2026 — meaning his known career earnings sit around $3.6 million including the bonus (Spotrac lists $2,795,376 in career earnings through 2025 before his 2026 salary is added). He remains under team control in his pre-arbitration years, with arbitration eligibility beginning in 2029 and free agency projected for 2032, per SportsJone — which is exactly why a long-term extension has become one of baseball’s most-watched storylines. The site’s other MLB bios, such as Alec Burleson‘s, show the same pattern: pre-arbitration paychecks while a player’s value runs far ahead.
