The Giants are heavily favored (-278 on the moneyline to win) when they square off against the Rockies (+225). The scheduled starters are Robbie Ray (3-0) for the San Francisco Giants, and Antonio Senzatela (1-4) for the Colorado Rockies.

San Francisco (19-13 overall, 9-5 home) enters Friday night's ballgame on a three-game skid, while Colorado (6-25 overall, 2-14 away) comes in on a two-game winning streak, having won Thursday's series opener 4-3.

Justin Verlander keeps getting let down by his offense, still searching for his first win for the Giants after a blown lead to the Rockies.
