Morgan Ensberg hit an RBI double and Adam Everett added a two-run single in the 11th inning, and the Houston Astros won their second road series of the season by beating the Mets 6-3 last night.

After losing to Pedro Martinez in the opener, the Astros won two straight and improved to 2-8 in road series this season – they are 7-23 away from home.

David Wright homered and drove in two runs for the Mets, but Houston opened the 11th with three straight hits off Heath Bell (0-3). Jose Vizcaino and Lance Berkman singled before Ensberg doubled to left to make it 4-3. One out later, Everett singled to right to chase Bell.

Russ Springer (1-2) pitched a scoreless inning for the win, and Brad Lidge struck out three batters in the 11th for his 15th save. He gave up a one-out double to Carlos Beltran, his third hit.

Leading off the eighth inning, Kaz Matsui appeared to be hit on the foot by a pitch from reliever Dan Wheeler, but plate umpire Gerry Davis looked unsure of the call until he inspected the ball and awarded Matsui first base. Astros manager Phil Garner came out to argue and was shown the ball.

Pinch-hitter Miguel Cairo sacrificed, and an out later Mike Cameron hit a grounder up the middle that Everett stopped with a dive. But he couldn’t make the throw from his knees and the game was tied at 3.

Mets starter Tom Glavine settled down after a shaky first inning, shutting down the Astros into the seventh. But the team that entered hitting a major league-worst .241 rallied for a 3-2 lead in the seventh – with a little help from a deflection.

Jason Lane doubled with one out and advanced to third when center fielder Beltran tried to backhand the ball and it skipped off the heel of his glove for an error. One out later, Brad Ausmus got just his second hit in 37 at bats against Glavine, a double to right that scored Lane.

Pinch-hitter Craig Biggio then hit a sharp grounder up the middle, which deflected off the mound toward the right side of the infield for an RBI single.

Glavine allowed three runs and seven hits in seven innings.

The Shea Stadium crowd of 30,737 booed former Yankees star Andy Pettitte when he took the mound in the first and each time he came to the plate.

Pettitte had his third straight strong start in an up-and-down season, limiting the Mets to two runs and four hits in six innings. He has given up just three runs in his last 19 innings but is 3-6 this season.

Wright homered off the left-field foul pole to tie it leading off the second. The Astros had opened with a run on four hits – including Berkman’s RBI single.
