The Cubs built their victory in the first inning, then held on through a furious Arizona rally to win 6-5 at Wrigley Field. Chicago scored three times before recording an out, establishing a lead that proved just enough to survive the Diamondbacks' late charge.
Colin Rea earned the victory with 5.1 innings of work, allowing 2 runs on 8 hits while striking out 6. The right-hander carried a 4.41 ERA into the game and improved to 4-1 on the season. Jacob Webb secured his first save with 2 scoreless innings, striking out 3 while allowing just 1 walk.
Michael Busch delivered the decisive blow in the opening frame, singling to left to bring home Alex Bregman and Nico Hoerner for a 2-0 lead. Carson Kelly followed immediately with another RBI single to center, scoring Ian Happ to make it 3-0. The Cubs extended their advantage to 6-1 through four innings, with Dansby Swanson driving in Kelly and Crow-Armstrong scoring on a Zac Gallen wild pitch before Bregman doubled home Swanson.
Gallen absorbed the loss, lasting just 3.2 innings while surrendering 6 runs on 7 hits. The Arizona starter walked 3 and struck out 3, falling to 1-2 with a 4.45 ERA. Geraldo Perdomo nearly completed the comeback with a three-run homer in the sixth inning, cutting the deficit to 6-5, but the Diamondbacks could not find the equalizer.
Chicago extended its winning streak to two games and improved to 19-12. Arizona fell to 16-14 after the loss. Bregman sits three doubles away from 300 career doubles.
