Rafael Betancourt survived a walk and a hit in the ninth to record his 13th save as the Rockies defeated the Cardinals, 3-2. Tyler Colvin hit a three-run homer in the third to give the Rockies the lead. Colvin's blast came after Matt Holliday gave the Cardinals a two-run lead in the first with his 14th roundtripper of the year. Joe Kelly pitched six innings and was charged with two of Colorado's three runs to suffer the loss. St. Louis had won its previous two contests. Adam Wainwright takes the mound tonight against Jeremy Guthrie in the third test of four at Busch Stadium.
