Latest Odds: Rockies - 123 Total 10.5

The Colorado Rockies will continue their pursuit of the first place San Francisco Giants tonight at 8:40 pm at Coors Field.

Right-handed starter Jhoulys Chacin (0-2, 4.76 ERA) will be countered by the right-handed Matt Cain (1-3, 4.33 ERA) in a battle of National League West division rivals.

Cain faces a difficult task tonight as he'll be asked to silence the most prolific offense in baseball. The Rockies have scored more runs than any other team, and at home, they're batting a collective .352. 154 of the team's MLB-leading 249 runs scored have been scored at Coors Field, a primary reason the Rockies are 15-6 at home.

The Rockies have not been kind to Matt Cain this year. In 13 innings pitched against the Rockies, Cain has surrendered 14 hits, eight earned runs and sports an ERA of 5.54. He's gotten a loss and a no-decision in that time frame.

Coors Field isn't just hostile to opposing pitchers; starter Jhoulys Chacin has had just one start at home this year and it was a five inning outing where he surrendered four runs to the Mets en route to a loss.

Chacin will look to improve on his last outing where he allowed three runs in a loss to the Kansas City Royals, but it's worth noting he retired 12 of the final 14 batters he faced.

The Giants will counter a stellar offense with a stellar pitching staff, sporting a cumulative team ERA of 3.21, No.5 in all of baseball. If Matt Cain can manage against the sluggers, he'll hand the ball over to a bullpen with an ERA of 2.21, No.3 overall in the game.

That isn't to say the Giants will only be relying on its pitching; they also boast a top-10 offense. They've actually scored more runs on the road (100) than at home (88).
