The Rockies (57-83) snapped a five-game losing streak with Monday's 6-5 win over the Giants and will hand the ball to Jhoulys Chacin (4-5, 4.50 ERA) on Tuesday. The Giants (79-62) will send Madison Bumgarner (14-10, 3.15) to the mound.
Despite his impressive line for the season, Bumgarner has struggled lately and looks to avoid losing his fourth straight start. He'll do so against one of his favorite opponents. In 57.1 career innings against Colorado, Bumgarner sports a 1.88 ERA.
On the flip side, Colorado's Carlos Gonzalez is a .368 career hitter against Bumgarner with two homers in 19 career at-bats, though Gonzalez is a mere 1-for-16 in his last five games.
The Giants, who lead the Los Angeles Dodgers by five games in the NL West, have won eight of 12 meetings with the Rockies this season. Root Sports-Rocky Mountain will carry the game locally.
