Mike Leake and Manny Parra combined on a four-hitter as the Reds shut out the Cardinals 4-0 at Busch Stadium. Shelby Miller allowed seven hits and three runs over six frames to fall to 0-and-2 with the loss. Matt Adams had the lone extra-base hit for St. Louis with a double. Kolten Wong, Matt Holliday and Yadier Molina had the other Cardinals' hits in defeat. The Cards start a three-game set with the Cubs Friday.
