Over five starts in August, Madison Bumgarner went 5-0 with a 1.43 ERA.
On Tuesday night, he suffered defeat for the first time since July 31.
The Giants' ace allowed just two runs over seven innings, but the Orange and Black dropped their fourth straight and fell to 5.5 games behind the Dodgers in the NL West.
