Adrian Beltre in lineup

OAKLAND, Calif. -- Texas Rangers third baseman Adrian Beltre is in the lineup as the designated hitter for Monday's game with the Oakland A's, one day after leaving the second game of a doubleheader with a left shoulder strain.

Michael Young, who left Sunday night's game early with a sore left Achilles, is playing third base.

Beltre hurt the shoulder diving for a ball in the ninth inning of the first game on Sunday and tried to play through it in the second game. But after trying to leap for a ball in the seventh inning, manager Ron Washington felt like Beltre didn't look right and took him out as a precaution.

Beltre and Washington stressed that the third baseman will be ready for the playoffs. He's been playing through a variety of ailments, including abdominal issues, and admitted that it would be nice for the club to clinch as soon as possible so he could get some additional days off.

But taking Beltre out of the lineup is very difficult right now, mainly because Beltre fights hard to stay in. Washington said he didn't want to send him right back on the field, so he's getting a half-day off.

"We're just being precautious right now," Washington said. "You may see him back in there (at third base) tomorrow. He'll be physically ready (for the playoffs)."

Beltre said everyone is playing through issues this time of year and that he will do what's necessary to help the club and take care of himself at the same time.

When asked if he would be ready for the playoffs, Beltre said: "I'm ready today."

Beltre is hitting .319 with 36 homers and 101 RBIs in 153 games for the Rangers this season. He's provided plenty of clutch hits and has had another solid defensive season.

Young said his Achilles has bothered him for a month now. It's something that has cropped up from time to time the past five years.

"I know how to manage it," Young said.
