Pitching matchup
SF: LHP Jonathan Sanchez (3-0, 1.42 ERA)
Sanchez made his Major League starting debut Wednesday against the Reds and tossed 5 2/3 innings of one-run, three-hit baseball. It will be the rookie's third appearance against the Rockies this season.
COL: RHP Denny Bautista (0-2, 5.66 ERA)
Bautista will make his first appearance as a Rockie on Tuesday, sliding into a sixth spot in the rotation. The right-hander has an effective slider and an upper 90s fastball, but fastball command has been an issue for him. He has made mechanical adjustments in his delivery, no longer throwing across his body.
Player to watch
Ray Durham is riding a four-game hitting streak, and is batting .500 (8-for-16) in that span. He had two doubles Sunday night and scored the game-winning run in Saturday's extra-inning thriller.
