Mark Teixeira's postseason is over

NEW YORK -- All-Star first baseman Mark Teixeira's season is over.

Switch-hitter Lance Berkman replaced him at first base for the Yankees' 7-2 win over the Rangers in Game 5 of the American League Championship Series.

Teixeira was removed from the Yankees' postseason roster Wednesday, after straining his right hamstring while running out a grounder against Texas in Game 4 Tuesday.

Yankees manager Joe Girardi said Teixeira would be replaced on the roster by infielder Eduardo Nunez.

If the Yankees overcome the 3-2 deficit against the Rangers in the best-of-seven ALCS, Teixeira would not be eligible for the World Series. Teixeira said the injury will need 6-8 weeks to heal.

In addition to installing Berkman at first base, Girardi moved up Robinson Cano to the No. 3 spot in the lineup against Rangers lefty C.J. Wilson. Berkman batted sixth.

"The way Robby has been swinging, we just talked about getting him more at-bats and moving him up. And somewhat leaving the rest of the lineup intact," Girardi said.

The Yankees got a scare in the fourth inning when Berkman wiped out while chasing a foul popup. His head snapped back as he slipped hard onto his back near the stands.

With the crowd hushed, Berkman rolled over onto his stomach as the Yankees came out to check on him. After a few tense moments he caught his breath, then got to his feet and remained in the game.
