The Milwaukee Brewers came back from two runs down to beat the Chicago Cubs 9-5 at Wrigley Field on Wednesday, September 2, 2026. Milwaukee's offense wore down a Cubs pitching staff that needed seven arms to get through nine innings, with Jackson Chourio leading the charge at 4-for-6 with a home run. Alex Bregman was the lone bright spot for Chicago, driving in four runs on two hits including a homer, but it wasn't nearly enough as the Cubs dropped this division matchup by four.

David Peterson Struggles Early, Cubs Pitching Staff Overwhelmed

The loss falls on starter David Peterson, who was tagged for 6 earned runs on 7 hits and 4 walks across just 3.2 innings. Peterson struck out four but couldn't strand runners when it mattered, and the Cubs found themselves chasing the game from the early innings. JoJo Romero earned the win for Milwaukee after tossing a clean inning of relief.

What followed Peterson in the Cubs bullpen was a parade of relievers who couldn't fully stabilize the game. Trent Thornton gave up 2 hits in 0.2 innings, though he held the Brewers scoreless. Ryan Rolison was the most effective arm out of the pen, covering 1.2 innings without allowing a hit or a run. Daniel Palencia surrendered a run on 2 hits in a clean inning of work, and Jacob Webb was touched for 2 earned runs on 1 hit in just a third of an inning. Colin Rea finished things off with 0.2 innings and 2 hits allowed but no runs. Caleb Thielbar provided a bright spot, striking out two in a scoreless inning of work.

Chourio and the Brewers Offense Too Much to Handle

Milwaukee's offense spread the damage across the lineup. Chourio was the standout, going 4-for-6 with a home run and an RBI. Five different Brewers batters recorded multi-hit games:

  • Jackson Chourio: 4-for-6, 1 HR, 1 RBI
  • Christian Yelich: 2-for-3
  • Andrew Vaughn: 2-for-3, 1 RBI
  • William Contreras: 2-for-5, 1 RBI
  • Cooper Pratt: 2-for-4, 1 RBI

On the mound, Milwaukee starter Jacob Misiorowski allowed 5 earned runs on 5 hits and 4 walks in 4 innings, striking out five. The Cubs had their chances early but could not sustain pressure as the Brewers' bullpen — JoJo Romero, Antonio Senzatela, Abner Uribe, Aaron Ashby, and Trevor Megill — combined to throw five scoreless innings to close out the game.

Bregman Provides the Only Real Offensive Punch for Chicago

Alex Bregman was the one Cub who kept his team in it, going 2-for-4 with a home run and 4 RBI. He was responsible for the bulk of Chicago's offense, but no other Cub in the boxscore highlights matched his production. The Cubs did rally at some point to cut into what became a 2-run deficit, per the game data, but Milwaukee answered and extended its lead, finishing with a four-run margin.

Turning Point: Peterson's Short Start Forces Early Bullpen Use

The turning point was Peterson's inability to get through the fourth inning. Getting just 3.2 frames from your starter in a division game puts enormous pressure on a bullpen, and while pieces of the Cubs relief corps held the line, the damage was already done. Webb's two earned runs in a third of an inning in the late innings served as the final nail, pushing the Brewers' lead to an insurmountable margin.

What's Next for the Cubs

The Cubs and Brewers continue their series, giving Chicago an immediate opportunity to respond in this division matchup at Wrigley Field. If the Cubs are going to make a statement in September, they'll need a starter to give them length and keep their bullpen from being taxed across multiple consecutive games. A repeat of Wednesday's pitching performance won't get it done.
