Jacob Misiorowski’s Meteoric Rise to MLB Ace

From “Baby Giraffe” to 105 MPH Firepower

Jacob Misiorowski, the Milwaukee Brewers’ newest star, has gone from a lanky high‑school phenom known as a “baby giraffe” to one of the hardest‑throwing pitchers in baseball. The Grain Valley, Missouri, product was already drawing Division I interest as a freshman, but his real breakthrough came after a dramatic growth spurt that added nearly five inches to his 6‑foot‑1 frame. “The best way for me to describe him would be like a baby giraffe,” said former Grain Valley coach Brian Driskell, recalling his early days on the mound. By the time he graduated, Misiorowski’s velocity had surged from 82 mph as a freshman to the mid‑90s, setting up a stunning junior season that included two no‑hitters.

The coronavirus pandemic forced the cancellation of Misiorowski’s senior year, leaving him without a competitive outlet and prompting a shift to nearby Crowder College. After a pesky meniscus tear required surgery, the young right‑hander faced two years without competitive pitching, yet he never lost confidence in his abilities. “It was more like competing with myself,” he later reflected, emphasizing the mental workout he performed during the idle periods. Those years of self‑work paid off when he returned to the mound as a sophomore.

The Turning Point at Crowder College

At Crowder, Misiorowski’s sophomore season became the catalyst for his rapid ascent up draft boards. He posted a 10‑0 record with a 2.72 ERA, striking out 136 batters in 76 innings, highlighted by an 18‑strikeout outing. Scouts in attendance noticed his velocity climb, with Anderson later recalling that “Miz” was throwing 96‑99 mph and touching 100 mph in a single game. The same season, a spectacular 92‑mph debut on a cold February gradually gave way to the electric stuff that would soon dominate national evaluations.

Milwaukee’s Bold Draft Decision

Leading up to the 2022 draft, Misiorowski’s name was a hot topic, but many teams labeled him a reliever, citing his elite velocity but erratic command. Brewers scouts Riley Bandelow and Drew Anderson, however, believed he could be a frontline starter, and they kept pushing his case. “A lot of people said, it just screams reliever,” Anderson recalled, noting that three‑quarters of the league missed his potential. Their persistence paid off when Milwaukee selected Misiorowski with the 63rd overall pick, a move Anderson called “the best kid” they’d ever evaluated.

After signing, Misiorowski moved through the minors methodically, striking out 320 batters in 233 2/3 innings from 2023‑2025 while posting a 3.04 ERA. The 2025 campaign saw him debut with a five‑inning no‑hit effort and a 102.3 mph fastball, quickly turning heads across the league. By season’s end, he was 5‑3 with a 4.36 ERA and 87 strikeouts in just 66 innings, signaling that his development was far from complete.

Brewers Ace Lights Up the Majors

Entering the 2026 season, Misiorowski has elevated his game to historic levels. He currently leads the league with a 1.62 ERA, a sparkling 10‑4 win‑loss record, and an MLB‑leading 167 strikeouts in 111 innings. His velocity has now cracked 105.5 mph, the fastest opener by a starter since pitch tracking began in 2008, and his walk rate sits at a tidy 6.8 %. The combination of raw power and refined control has transformed him into the Brewers’ unquestioned ace.

The shift in approach that allowed this success came from a simple mantra. “Your s***’s good enough to not have to nibble,” teammates told him, encouraging him to attack the middle of the plate. Misiorowski embraced the advice, resulting in a career‑best 39.3 % strikeout rate that leads baseball. The confidence buoying his performance extends beyond the mound; he’s known for his love of Pokémon cards and unfiltered excitement after big strikeouts, earning genuine affection from Milwaukee fans.

What Scouts Are Saying About the Phenom

Scouts who watched Misiorowski develop recall a rare blend of humility and raw talent. Bandelow praised his authenticity, calling him “a really nice kid that somehow throws 105.” Anderson’s enduring belief is evident: “Credit to Riley for being able to stick with him for all three years,” he noted, highlighting the rarity of such long‑term commitment. Their dedication wasn’t in vain—Misiorowski is now viewed as a potential face of baseball, a player who could define a new era of dominant, charismatic pitching.

Looking ahead, the trajectory suggests that the best may still be ahead. With a slender frame that continues to add strength and a mindset focused on continual improvement, Misiorowski appears poised to write a lasting chapter in Brewers history and beyond. His journey—from a “baby giraffe” in Grain Valley to an MLB ace wielding 105 mph heat—remains a story worth watching for years to come.
