HOUSTON, TX -- Omar Infante's bases-loaded two RBI single in the 12th inning lifted the Miami Marlins to a 5-3 win over the Houston Astros on Wednesday night.

Logan Morrison singled in the 12th before a walk by Giancarlo Stanton. Greg Dobbs grounded into a force out at second and left runners on the corners. Reliever David Carpenter (0-2) walked John Buck with two outs to load the bases and set up Infante's game-winner.

The victory improves the Marlins to 8-1 on their nine-game road trip.

Ryan Webb (2-1) pitched 1 1-3 scoreless innings for the win.

The Marlins had runners at first and second with no outs in the 10th after a single by Hanley Ramirez and Jed Lowrie's second error of the game, which allowed Morrison to reach. But closer Brett Myers retired the next three Marlins to escape the jam.
