SAN FRANCISCO — Evan Longoria and Darin Ruf launched back-to-back home runs in the second inning and the Giants spoiled Madison Bumgarner's return to San Francisco with a 4-3 win over the Arizona Diamondbacks on Saturday night.
Bumgarner (0-4) came off the injured list to make his first start in nearly a month after recovering from a mid-back strain. The left-hander allowed two earned runs on three hits in four innings, striking out two and walking a pair in his first-ever appearance against his former team.
Bumgarner spent his first 11 seasons with the Giants, winning three championships and the 2014 World Series MVP.
