CINCINNATI (AP) - Colby Rasmus' homer started St. Louis' eight-run onslaught against slumping right-hander Bronson Arroyo, and the Cardinals got another solid start from Chris Carpenter for a 10-1 victory over the Cincinnati Reds on Sunday.
Rasmus hit a two-run homer in the first off Arroyo (8-8), who is 1-5 in his last seven starts. A throwing error by third baseman Edwin Encarnacion let in a pair of runs in the fifth inning, helping the Cardinals pull ahead 8-0 with Arroyo on the mound.
Carpenter (6-3) bounced back from his worst start of the season, a 6-3 loss to the Giants on Tuesday. The right-hander gave up a run and five hits in seven innings, fanning Laynce Nix on a 94 mph fastball with his 104th and final pitch.
