Cubs Looking to Regain Early Season Mojo

Chicago won their second straight after a 10-game slide as they downed the Pirates on the road Thursday in the series finale. The Cubs entered Friday 31-26 and stood second in the NL Central, four games behind the Brewers for the top spot. On Thursday, Chicago finished with eight hits as Ian Happ (run, two RBI) had three hits while Seiya Suzuki (run, two RBI) added two. Happ (his 12th) went deep in the victory for the Cubs. Colin Rea (5-3) earned the win as he threw 5.1 innings, allowing two runs on four hits with three walks and five strikeouts before turning things over to the bullpen.

He is 1-2 with one save, a 2.01 ERA, a 0.985 WHIP, 14 walks and 47 strikeouts over 44.2 innings of work this season.

In his last three starts, Brown is 0-1 with a 2.40 ERA, a 1.13 WHIP, five walks and 20 strikeouts over 15 innings of work. Brown took the loss in his lone career start against the Cardinals, which came on June 23, 2025. He threw five innings, allowing eight runs on nine hits with two walks and three strikeouts, in an 8-2 Cubs loss. That outing came at Busch Stadium, giving him a passing familiarity with the park.
