Brad Ausmus drove in his fourth run of the night with the game-winning single in the 10th inning, and the Houston Astros overcame another blown save by Brad Lidge to beat the Oakland A's 5-4 Tuesday night.

Brad Ausmus drives in four runs including the game winner in 11 innings.

Ausmus also had an RBI double and a two-run homer, though none of that mattered when Mark Kotsay led off the ninth inning with a homer off Lidge, who was trying to close out a game for the first time since April, when manager Phil Garner demoted him from the role.

Lidge had pitched well lately as a setup man, allowing only one earned run in his last 19 2-3 innings. He's 0-for-3 on save opportunities this season.

Kotsay hit Lidge's third pitch into the right-field seats for his first home run of the season. Kotsay went 4-for-5, his best game since coming off the disabled list on June 1.

Adam Everett doubled with one out in the 10th before Ausmus singled off Ron Flores (0-1). Jason Kendall's throw to the plate was off line as Everett slid across the plate.

The Astros won for only the third time in seven games, and Oakland lost for only the second time in its last 10.

Notes: Craig Biggio had three hits including two doubles to move within 17 hits of the 3,000 plateau. Biggio now has 2,983 in his career. Slugger Lance Berkman served the first game of his two game suspension from his outburst in Colorado last week. Berkman says he would have served the suspension over the weekend, but injuries to Hunter Pence and Luke Scott would have left the club shorthanded.
