NEW YORK (AP) -- Brad Ausmus led off the 10th inning with his second homer of the season, Darin Erstad connected for his third three batters later and the Houston Astros rallied against the New York Mets' shaky bullpen for a 6-4 win Sunday.

Hunter Pence hit a two-run homer and Mark Loretta made an elastic catch to end an early bases-loaded threat as Houston overcame Carlos Beltran's two homers, improving to 3-3 on its seven-game road trip.
