Record Fastball and Swing of Momentum: Brewers–Cubs Series Highlights

On June 27 the Milwaukee Brewers defeated the Chicago Cubs 6-2 at Miller Park. Right-hander Jacob Misiorowski opened the game with a 105.5 mph fastball—tied for the third-fastest pitch ever recorded—before allowing a solo home run to Seiya Suzuki in the sixth. The following night the Cubs rebounded 8-2 at Wrigley Field. Ian Happ delivered a three-run homer in the sixth, and the Cubs added runs on back-to-back hits by Alex Bregman, Michael Busch, and Michael Conforto.

Both clubs sit near the top of the National League Central: the Brewers lead at 50-29, while the Cubs sit second at 44-38. Milwaukee entered the series on a five-game winning streak; Chicago had won four straight before a brief slump. The Cubs were already coping with four starters on the injured list, including Cade Horton (season-ending) and Phil Maton (right-knee tendinitis).

Brewers manager Pat Murphy noted that while Misiorowski’s velocity is “impressive,” there may be a physiological ceiling to how fast a pitch can travel. Misiorowski himself said he believes higher speeds are possible but emphasized that velocity alone does not win games. Both comments underscore the tension between raw speed and overall effectiveness.

• “I think I slipped a little bit on that pitch. My front foot slid out from under me.” — Jacob Misiorowski, RHP, Milwaukee Brewers

• “They had a gameplan coming in to battle me and foul s--- off,” — Jacob Misiorowski

ESPN

• “Science says you can hit 108. Someone eventually is going to hit it. If that's me, cool. I don't think that's something I need to focus on. Speed is cool but if it doesn't win a ballgame it doesn't matter.” — Jacob Misiorowski

• “I think there's a limit there.” — Pat Murphy, Brewers manager

ESPN

• “It's impressive. It feels like every time he goes out there, he's breaking a record of some sort.” — Garrett Mitchell, Brewers outfielder

The Cubs placed Phil Maton on the 15-day IL and released Tyler Beede, who elected free agency after a 12.71 ERA in Triple-A. Milwaukee activated left-hander Jared Koenig from the IL and optioned Craig Yoho to Triple-A Nashville. These adjustments tighten both clubs’ pitching depth as the division race tightens.

ESPN

Chicago’s newly acquired left-hander David Peterson (traded from the Mets for minor-league third baseman Cole Mathis) makes his first start for the Cubs on the upcoming series finale. Milwaukee will counter with Kyle Harrison, the 8-1 right-hander who posted a 2.50 ERA in his last start. The outcomes will shape the Central’s late-season momentum.
