Chicago defeats San Francisco 5-1 on Friday night as Javier Assad pitches effectively and Michael Busch delivers a key three-run homer. The Cubs break a scoreless game in the fourth inning when Seiya Suzuki drives in a run with an RBI double and later scores on Nico Hoerner’s sacrifice fly. In the fifth, Busch hits a three-run home run into McCovey Cove, extending Chicago’s lead. Assad improves to 4-1, striking out five and walking one while allowing three hits over six innings to earn his third straight decision, spanning seven starts. After an error on a pickoff attempt in the fourth, Assad prevents further damage by stranding Bryce Eldridge on third. The bullpen completes the win: Hoby Milner pitches the seventh and Trent Thornton works the final two innings. The Giants add a solo home run by Eldridge in the ninth. Chicago wins for the third time in its last seven games. The Giants had recent success against the Cubs earlier in the week, but are held to the single run.
