The Milwaukee Brewers erased a three-run deficit and pulled away for a 9-4 victory over the Chicago Cubs at Wrigley Field on Tuesday, September 1, 2026. Milwaukee's comeback — fueled by home runs from Joey Ortiz and Christian Yelich and a Cubs bullpen that allowed six earned runs across four relievers — hands Chicago a lopsided division loss that stings in the thick of the regular season. The five-run margin tells the full story: the Cubs couldn't hold their early lead, and the Brewers made them pay.

Brewers Offense Breaks Open the Game After Cubs Take Early Lead

Chicago built a lead that starter Matthew Boyd couldn't protect. Boyd worked 5.1 innings, giving up 7 hits and 3 earned runs while striking out 3. He kept the Cubs in it long enough, but the moment he exited, the game unraveled.

Daniel Palencia inherited the mess and made it worse. The right-hander allowed 2 hits and 2 earned runs in just two-thirds of an inning and was tagged as the losing pitcher. Ryan Zeferjahn followed and surrendered another 2 earned runs on 2 hits in 0.2 innings. Caleb Thielbar added 1 earned run on 1 hit and 2 walks across 0.2 innings. By the time Tyler Ferguson entered to get the final outs, the Cubs were chasing a five-run hole they couldn't climb out of. Ferguson allowed 1 earned run over 1.2 innings in a mop-up role.

In total, the Chicago bullpen allowed six earned runs across four appearances — a collective collapse that turned a winnable divisional game into a blowout.

Ortiz and Yelich Power Milwaukee With Home Runs

On the Milwaukee side, Joey Ortiz delivered the signature blow: he went 2-for-4 with a home run and 2 RBI. Christian Yelich added a home run of his own, going 1-for-4 with 2 RBI. Those two swings provided the power surge that put the game out of reach.

Jackson Chourio (2-for-5), Brice Turang (2-for-4), and William Contreras (2-for-5, 1 RBI) rounded out a Brewers lineup that punished Cubs pitching with consistency. Milwaukee put up crooked numbers after taking the lead and never looked back.

Turning Point: The Bullpen Bridge Collapses in the Sixth

The turning point was the handoff from Boyd to Palencia in the sixth inning. The Cubs held a lead at that juncture, but Palencia could not record outs without damage. Two hits, two runs, and the lead evaporated. Zeferjahn then entered and continued the bleeding. What had been a Cubs advantage became a Milwaukee cushion within a single frame. That sequence — the transition from starter to bullpen — is where this game was lost.

On the mound for Milwaukee, Robert Gasser exited after 4.1 innings having allowed 2 earned runs on 3 hits and 2 walks with 4 strikeouts. Antonio Senzatela bridged an inning for the Brewers and was credited with the win, allowing 1 earned run in 1.0 inning. The Milwaukee bullpen locked down the rest: JoJo Romero, Abner Uribe, Aaron Ashby, and DL Hall combined for 3.2 scoreless innings to close it out.

What's Next for the Cubs

Chicago will look to respond quickly in this division series. Wrigley Field doesn't forgive slow starts to series, and the Cubs now face the challenge of bouncing back against a Brewers squad that just demonstrated it can manufacture big innings against Chicago's pitching staff. The bullpen's performance Tuesday will need to be addressed — six earned runs across four arms in a division game is not sustainable.

  • Matthew Boyd: 5.1 IP, 7 H, 3 ER, 1 BB, 3 K
  • Daniel Palencia (L): 0.2 IP, 2 H, 2 ER
  • Ryan Zeferjahn: 0.2 IP, 2 H, 2 ER, 1 K
  • Caleb Thielbar: 0.2 IP, 1 H, 1 ER, 2 BB
  • Tyler Ferguson: 1.2 IP, 1 H, 1 ER, 2 BB, 1 K

The Cubs scored 4 runs but left themselves without answers once Milwaukee's lineup got rolling. In a divisional matchup with this much at stake during the regular season, Tuesday's result is one Chicago will need to put behind them fast.
