Franklin Morales will start for the Rockies against the Giants' Matt Cain tonight when Colorado meets San Francisco for Game Two of their series at AT&T Park.
Morales will try to put the Rockies back in the "W" column after a 4-1 loss last night ended Colorado's three-game winning streak.
The Giants scored three times in the eighth inning to get the win.
Rich Aurilia snapped a one-all tie with an RBI single before Kevin Frandsen added a two-run double. Ryan Klesko hit an RBI single in the fourth as the Giants earned their 10th victory in 12 games.
Jorge Julio was tagged for three runs and five hits in just one-third of an inning to fall to 0-and-5.
With the loss, the Rockies fall four-and-a-half games behind the San Diego Padres in the NL wild-card race.
