The struggling St. Louis offense finally came to life on Thursday. The Cardinals scored eight runs in the second inning on their way to a 9-5 over San Francisco, taking the final game of a four-game series with the Giants. Edgar Renteria and Scott Rolen each hit three-run home runs for the Cardinals. Scott Rolen added a solo shot as the Cardinals avoided what would have been the Giants first four-game sweep in St. Louis since 1912. Ten Cardinals combined for 14 hits in the offensive attack. Jason Simontacchi (6-4) picked up the win for the Cardinals. He went six innings, and allowed five runs on seven hits. The Cards (44-40) are now tied with Houston on top of the N.L. Central and one game ahead of Chicago. The Cardinals open a three-game series against the Cubs at Wrigley Field this afternoon.
