On the day the Cubs fired general manager Jim Hendry, they came away with a 5-4 victory over the Cardinals. Tyler Colvin won the game with a walk off, pinch-hit RBI single in the bottom of the 10th at Wrigley Field.  Geovany Soto scored the game winning run and was 2-for-4.  Darwin Barney chipped in with a solo homer in the fifth inning, his second of the season.  Reliever Sean Marshall earned the victory to improve to 6-and-5.  Jaime Garcia pitched six-and-a-third innings of three-run ball in a no-decision for the Cardinals.  Octavio Dotel took the loss.
