After a nice 6-2 victory on Friday night, the Brewers will look to secure another series win over the Cubs in the second game on Saturday night.
Left-hander Kyle Harrison gets the start for the Brewers, while the Cubs will deploy a left-hander of their own in David Peterson, who they acquired in a trade with the Mets earlier this week.
Harrison, 24, is coming off his first appearance in which the Brewers lost in more than two months, dating back to April 11 across 10 starts. He didn’t look bad in that
one, as he exited with a lead against the Braves after allowing two runs on four hits and no walks with seven strikeouts over 6 1/3 innings. For the season, he’s 8-1 with a 2.50 ERA, 3.05 FIP, and 87 strikeouts over 72 innings.
Peterson, 30, spent the first seven years of his career in New York before the trade this week, meaning this will be his first non-Mets appearance. After a great season in 2024 (2.90 ERA, 101 strikeouts over 121 innings), he struggled a bit in 2025 (4.22 ERA), but he’s been even worse in 2026 (6.09 ERA over 68 innings across 16 appearances (eight starts)). His last appearance was a four-inning start against the Phillies, when he allowed five runs (four earned) on six hits and a pair of walks, striking out five in a 6-2 loss.
It’s a lefty-heavy lineup, as Jackson Chourio leads off, with Brice Turang and William Contreras to follow. Andrew Vaughn bats cleanup and Gary Sánchez slides into the five-hole as the DH. Blake Perkins, Sal Frelick (the lone true lefty), Cooper Pratt, and Joey Ortiz round things out.
First pitch in this one is at 6:10 p.m. on Brewers.TV and the Brewers Radio Network.
