Jacob Misiorowski

Jacob Walter Misiorowski, nicknamed "the Miz," is an American professional baseball pitcher for the Milwaukee Brewers. Born on April 3, 2002, in Blue Springs, Missouri, he made his MLB debut in 2025 and earned an All-Star selection that same year. In 2026, he set the record for the fastest pitch thrown by a starting pitcher since tracking began in 2008, reaching 105.5 mph. He also threw over 700 pitches at 100 mph or faster that season, establishing himself as one of the most dominant arms in the game. [edit]

Misiorowski grew up in Grain Valley, Missouri, a small town east of Kansas City. He attended Grain Valley High School, where he posted a 9–2 record with a 1.48 ERA as a junior in 2019, earning All-State honors. At a Perfect Game event in August 2017, he was listed at 6'5", 160 pounds, throwing in the low-to-mid 80s, topping at 84 mph. He verbally committed to Oklahoma State. His senior season in spring 2020 was canceled due to COVID-19.

In fall 2020, he enrolled at Crowder College in Neosho, Missouri. At Crowder Scout Day that fall, he threw 91–95 mph and was listed at 6'7", 190 pounds. He appeared in only two games during spring 2021. By fall 2021, at age 19.5, he threw 98 mph at Crowder Scout Day. In spring 2022, he had a breakout season: 10–0 in 15 starts, 2.72 ERA, 136 strikeouts in 76 innings, earning NJCAA Division I Second Team All-American honors and a commitment to LSU. In summer 2022, he participated in the MLB Combine, averaging 99.8 mph on his fastball and topping at 100.7 mph. [edit]

The Milwaukee Brewers selected Misiorowski in the second round (63rd overall) of the 2022 MLB June Amateur Draft. He signed on August 10, 2022, for a bonus around $1.5–2 million. Over the next three minor league seasons, he compiled an 11–9 record, 3.04 ERA, and 320 strikeouts in 233.2 innings.

He made his MLB debut on June 12, 2025, against the St. Louis Cardinals, pitching 5.0 innings with 0 hits allowed, 5 strikeouts, and 0 earned runs, earning the win. In his rookie season, he went 5–3 with a 4.36 ERA and 87 strikeouts in 66 innings, and was selected to the MLB All-Star Game. In 2026, he posted a 10–4 record with a 1.62 ERA, 167 strikeouts in 111 innings, and a 0.76 WHIP through July 20. On May 25, 2026, against the St. Louis Cardinals, he threw 57 pitches at 100+ mph, the most in a single game in MLB history. He also set the record for fastest pitch by a starting pitcher at 105.5 mph. He was named to his second consecutive All-Star Game in 2026. [edit]

Misiorowski is portrayed as a mild-mannered, soft-spoken individual who becomes a ferocious competitor on the mound. Media describes him as a "gangly stick of dynamite" and a "flamethrowing right-hander." His signature style is overpowering velocity with improving command. There is no official fandom name, but fans and media refer to his starts as "Miz nights." His social media voice is professional and focused on baseball content. New merchandise reading "Miz Limit: 104" has been released, reflecting his record-breaking velocity. [edit]

Jacob Misiorowski commands a global audience that spans the traditional boundaries of professional sports, drawing attention through unprecedented velocity and a cultural footprint that has begun to intersect with mainstream entertainment. His standing in the hierarchy of public figures is formally recognized by the iFANN Global Fame Rankings, which place him as the 13th most famous person in Baseball, a position he has held steady since the previous measurement cycle. This ranking reflects his rapid ascent from a draft pick to a generational talent whose dominance on the mound has captured the imagination of fans worldwide. While his influence is deeply rooted in the Milwaukee Brewers organization, his personal brand has evolved beyond standard athletic fandom. The collective identity of his supporters remains without a formalized moniker, though the community often refers to his appearances as "Miz nights" and has adopted the playful nickname "Les Misiorowski" for merchandise and social commentary. This grassroots adoption suggests a fanbase that is highly engaged and quick to mythologize his performance style, yet no official campaign or ritual has emerged to define the group. The absence of a specific name like those found in pop music does not diminish his reach; rather, it indicates a following that operates within the established infrastructure of baseball culture while generating its own unique vernacular around his exploits.[edit]

His surname provides the origin of his nickname, "the Miz," a shorthand that has become ubiquitous in media coverage. Before committing to play college baseball at Oklahoma State, and subsequently LSU, he spent time at Crowder College where he appeared in only two games during his first spring season. His development trajectory is marked by a dramatic increase in velocity, rising from 84 mph as a high school sophomore to the record-breaking 105.5 mph recorded in his debut season. He stands as one of just two Crowder College alumni currently on the Milwaukee Brewers roster, joining Aaron Ashby. Observers note that his delivery generates over seven feet of extension, creating an optical illusion of even greater speed for opposing batters. In August 2026, he achieved a historic statistical milestone by becoming the second-fastest pitcher in MLB history to reach 200 strikeouts in a single season, a feat completed by mid-August that year. Concurrently, rumors circulated regarding a potential crossover appearance on WWE's Raw in Milwaukee, adding a layer of speculative lore to his career narrative. This period also saw the emergence of the "Les Misiorowski" branding, where fans began producing and wearing merchandise that punned on his name, signaling an early stage of cultural myth-making surrounding his dominance.[edit]

Misiorowski is the son of Walter and Heidi Misiorowski. His father played college baseball at Missouri Western State University, and his mother played college volleyball there. He has one sister, Olivia, who played volleyball at Crowder College. The family lived in Grain Valley, Missouri, during his upbringing. [edit]

Misiorowski is a member of the Milwaukee Brewers organization, his sole MLB team. He shares a Crowder College alumni connection with fellow Brewers pitcher Aaron Ashby. His rise has been covered extensively by The Athletic writer Cody Stavenhagen. [edit]

As of 2026, Jacob Misiorowski keeps his personal relationships private. There are no confirmed public romantic relationships reported by credible outlets. He is currently single. [edit]
