A Transformation in the Making
To the casual observer, Milwaukee Brewers ace Jacob Misiorowski looks like a natural-born baseball phenomenon. Over the last year, the 24-year-old has transitioned from a promising hard-throwing prospect into arguably the most dominant pitcher in Major League Baseball. Known affectionately as "The Miz," the two-time All-Star now regularly lights up radar guns with fastballs exceeding 100 mph, captivating fans every time he steps onto the mound.
However, his path to superstardom was far from guaranteed. It was a winding, often unpredictable road characterized by late growth spurts, injuries, and a relentless need to refine his raw talent.
The "Baby Giraffe" Days
Misiorowski’s journey began at Grain Valley High School in Missouri. His high school coach, Brian Driskell, recalls a 14-year-old who was talented but physically unrefined. "The best way for me to describe him would be like a baby giraffe," Driskell said. "He was about 6 feet tall, just long limbs and skinny. He was an explosive athlete, but he was still learning how to control his body."
Even as a freshman, Misiorowski showed rare velocity, hitting 82 mph—a speed most teenagers in the area couldn't dream of reaching. While the raw power was present, the command was initially lacking. It wasn't until a massive growth spurt during his sophomore year, where he gained several inches in height, that his potential truly began to crystallize.
Scouting a Rising Star
By the time Misiorowski reached his junior year, he stood at nearly 6-foot-7. His unique frame allowed for an unusual pitching delivery that hid the ball well, making him a nightmare for opposing hitters. Milwaukee Brewers scouts Riley Bandelow and Drew Anderson were among the first to recognize his potential.
"Watching him pitch and move on the mound, this was MLB The Show create-a-player stuff," Bandelow shared. "The delivery was funky, but the athleticism and power were like nothing I had ever seen before."
Overcoming Setbacks
The road hit a significant hurdle in 2020. The pandemic canceled his senior season, and a meniscus tear at Crowder College sidelined him for his freshman year. Yet, through years of uncertainty and limited game footage, the Brewers remained steadfast in their belief. "I'm basically sitting there for two years saying this is the best kid," Bandelow recalled. "I'm all-in on this kid and have nothing to really back it up with."
The faith eventually paid off. In his sophomore year at Crowder, Misiorowski regained his health and began consistently hitting 96–100 mph. The Brewers finally selected him in the second round of the 2022 draft.
Becoming the Ace of the Majors
Since joining the professional ranks, Misiorowski has steadily evolved. By 2026, he reached historic levels of performance. He currently boasts an MLB-leading strikeout rate and has recorded a staggering 105.5 mph fastball—the fastest mark by a starter since pitch tracking began in 2008.
His secret this season? A shift in mindset. As Misiorowski explained, he stopped trying to "nibble" at the corners of the strike zone and started trusting his stuff:
"I had teammates tell me, 'Hey, your stuff is good enough to not have to nibble. Go middle.' And I trusted it."
The Person Behind the Pitcher
Despite his intimidating presence on the mound, those close to him describe him as remarkably grounded. Whether he is collecting Pokémon cards or simply enjoying his time in the clubhouse, Misiorowski has remained a humble figure. "He's just so wholesome," Bandelow said. "A really nice kid that somehow throws 105."
As he continues to cement his legacy, Misiorowski looks poised to become one of the faces of the sport, representing a rare blend of elite competitiveness and genuine character that has made him a fan favorite in Milwaukee.
