Matt Carpenter and Yadier Molina powered the St. Louis Cardinals to their latest win, and both have played key roles in their team's recent mastery of the Colorado Rockies. With their help, the Cardinals will attempt to secure another victory in the series Tuesday night while ending the Rockies' season-high win streak. Carpenter hit his fifth homer in eight games Sunday night and Molina provided a go-ahead, two-run double as the Cardinals (20-18) avoided a three-game sweep to the Los Angeles Dodgers with a 5-2 win.
