What’s Happening

The Chicago Cubs enter their upcoming series against the Milwaukee Brewers carrying significant momentum from a recent loss, having dropped an 8-6 decision to the Toronto Blue Jays on June 20, 2026 at Wrigley Field. That defeat was compounded by the rescheduling of their Father's Day game on June 21 due to inclement weather, forcing the Cubs to adjust their pitching rotation and travel schedule. The Cubs now face a Brewers team that has been dealing with its own instability, as manager Pat Murphy announced on June 21 that he will undergo back surgery on the team's Thursday off-day, just one day before the start of this critical three-game set against the Chicago Cubs.

The pitching matchup for Friday's series opener has drawn national attention, with Brewers fireballer Jacob Misiorowski taking the mound against the Chicago Cubs on June 26 as part of MLB's Friday Night Baseball streaming package. Misiorowski previously blanked the Cubs over six innings at Wrigley Field on May 19, a performance that underscored his emergence as a dominant force in the Brewers' rotation. The Cubs will be seeking redemption against the right-hander, but their recent offensive struggles—scoring just six runs in their last two games combined—raise questions about their ability to generate consistent offense against elite pitching.

This series carries significant implications for the NL Central standings, as the Brewers currently hold a 70% probability advantage over the Cubs in market assessments of the matchup. Milwaukee's depth has been tested by Murphy's impending surgery—he also plans to undergo hip surgery on July 13 at the start of the All-Star break—but the team has maintained consistency behind a strong pitching staff. For the Chicago Cubs, the series represents a critical juncture: a sweep would close the gap in the division, while a series loss could widen the deficit heading into July. The Cubs' bullpen, which allowed five runs in the final three innings against Toronto, will need to tighten up against a Brewers lineup that ranks among the league's best in run production over the past month.
