The San Francisco Giants defeated the Philadelphia Phillies 3–1 on Monday night at Oracle Park, breaking a 1–1 tie with two runs in the eighth inning. Philadelphia starter Cristopher Sánchez limited San Francisco to one run over seven innings, but the Phillies’ offense managed just four hits against rookie right-hander Landen Roupp and the Giants’ bullpen. Post-game attention focused on home-plate umpire Phil Cuzzi, whose strike-zone judgments drew sharp criticism from the Phillies. Cuzzi twice called high pitches strikes on Bryce Harper, and later declined to ring up Matt Chapman despite three borderline offerings from reliever Orion Kerkering. Chapman subsequently singled, igniting the decisive rally. “He knows he missed them. Sometimes that happens. Umpire took over the game,” Harper said after the loss. Manager Rob Thomson added that the calls “totally changed” key at-bats. Major League Baseball had no immediate comment on the officiating. The clubs continue their series Tuesday with Taijuan Walker scheduled to start for Philadelphia.
