The first leg of their West Coast swing was a disaster. The Colorado Rockies hope for better luck on the second leg this weekend. The Rockies open a three-game series in San Diego tonight against the Padres. Colorado swept the Padres at Coors Field last weekend but couldn’t carry that momentum to San Francisco, where they dropped three straight to open the trip. Jon Garland takes the mound for the Rockies tonight, facing San Diego’s Tyson Ross. ESPN Radio 1410 will have the action, with pregame coverage at 8:30 and the first pitch at 9:10.
