Kyle Harrison, acquired by the Milwaukee Brewers in a February trade with the Boston Red Sox, amazed fans during his first pitching appearance as a Brewer on Tuesday. Facing Team Great Britain‘s World Baseball Classic roster in an exhibition game, Harrison pitched three scoreless innings, showcasing a changed pitch that looked far more effective than what he had thrown in previous seasons. This turnaround is part of what makes Kyle Harrison pitching transformation so notable.
Significant Improvement in Harrison’s Change-Up Pitch
Harrison’s standout feature in the game was a newly refined change-up with considerably more downward movement compared to the version he used while with Boston’s Triple-A and major league teams. This improvement quickly captured the attention of the baseball community online, with many praising the Brewers’ innovative pitching program for the enhancement.

According to Curt Hogg of the Milwaukee Journal-Sentinel, Harrison began developing the “kick-change” grip over the summer while still with Boston. He further polished the pitch during winter training in Arizona, working alongside former San Francisco Giants teammate Hayden Birdsong before receiving additional refinement from the Brewers.
How the Brewers Helped Harrison Unlock His Potential
Harrison revealed that although the Brewers knew the change-up was new, they were unaware he had struggled with it previously. He explained,
“From the first bullpen, they just told me to throw it with conviction. They were like, ‘It doesn’t look new. You’re throwing it with conviction.’ That’s just something that they do a really good job with, is coming in and letting you do you. It’s, ‘Let’s see what you do.’”
“They’re obviously going to tweak and change some things but I just love how open they are and it’s kind of like my show.” — Kyle Harrison
This supportive approach allowed Harrison to feel confident and take ownership of his pitching, which helped accelerate his progress.
Broader Implications for Harrison and the Brewers’ Pitching Staff
While offseason adjustments are common among young pitchers trying to establish themselves, Harrison’s revamped change-up appears to represent a significant leap in his pitch arsenal. His progression adds promising depth to the Brewers’ pitching rotation, which, although filled with unproven talent, is viewed as a source of potential success.
Kyle Harrison’s pitching transformation signals a hopeful future for both the player and the Milwaukee Brewers, as his improved skills could contribute to the team’s competitiveness in the upcoming season and beyond.
