Following Thursday's off-day, Madison Bumgarner (6-6) will make what could be his final start of the season when the Giants open a three-game series at St. Louis on Friday. The Giants could tweak their starting rotation to allow Bumgarner to face the Dodgers at home on Sept. 28 -- but only if the game has postseason implications for Los Angeles. Otherwise, Bumgarner will begin resting for 2019. St. Louis will counter with right-hander John Gant (7-6).
