Yankees happy to get Teixeira back in lineup

First baseman goes through full batting practice before finale with A's

OAKLAND -- The Yankees allowed themselves a sigh of relief on Sunday morning when Mark Teixeira arrived at the O.co Coliseum and announced that he was ready to play, one day after a sore left rib cage knocked him out of the lineup.

"I'm sure I'll be all right," said Teixeira, who went through a full batting practice and reported no issues.

Yankees manager Joe Girardi was relieved to learn that Teixeira's issue was not related to the oblique, which could have necessitated a stint on the disabled list. Teixeira leads the Yankees in homers (11) and RBIs (31).

"He's a big home run threat. He's an RBI guy," Girardi said. "He's huge in the middle of the order between some lefties; a switch-hitter that really does damage against left-handers if they want to bring in a lefty to face some of our guys."

Teixeira likened the issue more to a spasm below his left shoulder.

"We're not sure exactly what it is," Girardi said. "I think we all wake up with some aches and pains some days, and the next day, you feel a lot better. It's hard to say what exactly it was."

Beltran's mistake leads to inning-ending DP

OAKLAND -- Carlos Beltran hit the ball hard in all four of his plate appearances on Sunday, which should represent a very encouraging sign for the Yankees. But his mood was soured by a mental lapse in the 10-5 loss to the A's.

With one out and a runner at first base in the eighth inning, Beltran hit a line drive that shortstop Jed Lowrie fielded on a hop, tossing to second baseman Nick Punto to force out Brian McCann.

Thinking there were two outs already, Beltran peeled off toward the first-base dugout. First-base umpire Dan Iassogna ruled that Beltran had abandoned the base and called him out, finishing off a most rare double play.

"It's an embarrassing play," manager Joe Girardi said. "It's probably happened to all of us. A lot of times, it's more that you slow up running to the bag as opposed to peeling off. It's a lot more glaring when that happens."

The Yankees were trailing, 10-3, at the time. Beltran said that something like that had never happened to him before, and that someone in the dugout had told him to get back to first base.

"It was too late to come back," Beltran said.

Beltran finished the afternoon 2-for-4, slugging a solo homer in the seventh inning off A's reliever Ryan Cook.

"The good thing about Carlos is he swung the bat well today," Girardi said. "He hit four balls on the screws. That's a good sign."

Yanks confident Solarte will get going at plate

OAKLAND -- The Yankees are not ready to push the panic button on Yangervis Solarte, who entered Sunday's game hitless in his last 16 at-bats.

"I think he'll get going. I think it's just kind of what you go through as a hitter," manager Joe Girardi said. "The West Coast hasn't been real kind to him, so he's probably glad we're going home after today. You kind of go through it. He'll be fine."

Solarte got the nod at second base for the second consecutive day on Sunday, as the Yankees try to give Brian Roberts (sore right knee) extra rest leading into Monday's off-day.

Girardi said that he prefers to play Solarte at second base over Kelly Johnson, who started at third base, because most of Johnson's defensive attention has been focused at the infield corners.

"Kelly really hasn't done a lot of work at second this year," Girardi said. "Solo has done a little bit more, and that's kind of why we stuck with it."

Bombers bits
