Nothing separated the teams for most of the afternoon at Wrigley Field. Then, with the game tied at 2-2 in the bottom of the ninth, Seiya Suzuki singled to left and Crow-Armstrong crossed the plate to end it. The Cubs won, 3-2, extending their winning streak to two games.
Shota Imanaga anchored the start, working 6.1 innings and allowing 2 runs on 9 hits with 4 strikeouts and no walks on 97 pitches. He did not factor in the decision. Trent Thornton followed with a clean inning of relief — 1.0 innings, 1 hit, no runs, 1 strikeout — and earned his third win of the season against two losses, carrying a 2.63 ERA.
San Diego built a 2-0 lead through four innings. Bogaerts scored in the third on a fielder's choice by Fernando Tatis, and Xander Bogaerts himself drove in Andujar with a double to left in the fourth. Chicago answered in the fourth when Michael Conforto singled to right to score Suzuki, cutting the deficit to one. In the fifth, Suzuki's sacrifice fly to center brought Dansby Swanson home to tie the game at 2-2. The score held there until Suzuki's walkoff single in the ninth.
San Diego reliever Jason Adam took the loss, his second of the season against two wins. He allowed 1 run on 2 hits in 1.0 inning, with his ERA at 2.51. The Padres, who had 11 hits on the day, could not protect the lead their bullpen inherited.
Chicago improved to 46-38, winners of two straight. San Diego fell to 43-39, dropping its second consecutive game. Suzuki finished 2-for-4 with 2 RBI and is one home run away from 100 in his career.
