Colorado Rockies right-hander Chi Chi Gonzalez is scheduled to make his return from almost a three-year major league absence when he takes on Madison Bumgarner and the host San Francisco Giants in the second game of a three-game series Tuesday night. The Rockies got shutout pitching from righty Jon Gray and three relievers to win the series opener 2-0 on Monday night, spoiling a five-inning, 11-strikeout effort by Giants left-hander Drew Pomeranz. Gonzalez, 27, blew out the ulnar collateral ligament in his pitching arm in spring training with the Rangers in 2017 after he went 4-8 with a 4.54 ERA for Texas over the previous two seasons.
