OAKLAND Carlos Corporan hit an RBI double in the 11th inning, lifting the Houston Astros to a 2-1 win over the A's on Wednesday night.
Jose Altuve singled with one out off A's reliever Sean Doolittle and was headed for third on Corporan's double when Oakland center fielder Chris Young bobbled the ball caroming off the wall. Altuve alertly rounded third and scored the tiebreaking run while Corporan was caught in a rundown between second and third.
Chris Carter homered and Jonathan Villar had two hits for the Astros. Houston has won the first two games of the series after dropping 11 of the first 12 between the division rivals this season.
Yoenis Cespedes singled and scored Oakland's run. The A's have dropped nine of 13 and fell two games behind first-place Texas in the West.
Lucas Harrell pitched one inning for the win and Josh Fields earned his second save.
Corporan, whose homer in the eighth inning broke up a no-hit bid by Texas pitcher Yu Darvish on Monday, entered the game as a defensive replacement in the ninth inning. He hit the first pitch from Doolittle off the wall in left-center. Young fielded the ball cleanly but bobbled it, allowing Altuve to score.
The A's got the potential tying run on base in the 11th on Eric Sogard's leadoff double, but Fields struck out Alberto Callaspo, Jed Lowrie and Josh Reddick.
Oakland also missed a chance to win the game in the 10th when Houston left fielder Robbie Grossman made a leaping grab of Young's deep fly at the fence. Young also barely missed homering in the ninth inning Tuesday on a foul ball that was reviewed.
Carter homered off A's starter Jarrod Parker leading off the seventh. Carter hit Parker's first pitch into the seats in left field, a towering solo shot to put the Astros up 1-0.
Brandon Moss's double in the seventh tied the score.
Houston's Jarred Cosart, the first pitcher in franchise history to begin his career with five consecutive starts of five-plus innings while allowing two or fewer runs, kept the A's silent early. He allowed only one runner past first base through six innings and didn't give up a fly ball out until Josh Donaldson's sinking liner to center leading off the fifth.
