OAKLAND -- Adrian Beltre was in the lineup, one day after coming out of Game 2 of Sunday's doubleheader with a strained left shoulder. But Beltre started at designated hitter instead of third base.

The question is whether Beltre needs time off to rest the shoulder for the playoffs.

"No ... I just don't need to," Beltre said. "Everybody goes through stuff. It's October. Everybody's got lingering injuries and stuff. It's not a big deal."

It is if Beltre is not ready for the playoffs.

"I think I'll be sore for a couple of days, but I'll be good for the first series," Beltre said.

Beltre admitted it would be nice if the Rangers could clinch the American League West as soon as possible.

"That would be awesome," Beltre said. "It would give guys one or two days off and set the rotation. I'd rather clinch now than wait for the last game."

Michael Young started at third base on Monday even though he is dealing with a sore left Achilles tendon. He said he has been dealing with it for five years, but it flared up the last month. He left Game 2 on Sunday after six innings as a precautionary measure.

Young was playing second base on Sunday. He said it's much easier to play one of the corner positions.

"I've dealt with it before," Young said. "I know how to manage it. It's no big deal."

Rangers ponder options for postseason roster

OAKLAND -- Rangers general manager Jon Daniels and assistant general manager Thad Levine have traveled with the team to Oakland for meetings with manager Ron Washington and the coaching staff about the composition of the playoff roster.

There are three areas to discuss: starting rotation, bullpen and bench.

Yu Darvish will likely be the Rangers' No. 1 starter with Matt Harrison right behind him. Darvish right now is ahead of Harrison in the rotation. He made his final start on Sunday while Harrison is scheduled to go Tuesday. The Rangers are expected to keep them in that order going into the playoffs. Ryan Dempster and Derek Holland will be the other two starters, but in an order yet to be determined.

The bullpen is unknown because the Rangers don't know if Mike Adams will be physically ready for the first round. The Rangers know that Alexi Ogando and Koji Uehara will be the right-handed setup relievers behind closer Joe Nathan, and Robbie Ross will be the left-hander. That leaves four spots to be determined. The choices include veterans Roy Oswalt, Scott Feldman and Mark Lowe, rookies Martin Perez and Tanner Scheppers and left-hander Michael Kirkman.

There is one spot on a four-man bench that will include catcher Geovany Soto, infielder Jurickson Profar and outfielder Craig Gentry. The Rangers would like it to be infielder Mike Olt because they want insurance with Adrian Beltre dealing with physical issues. But the Rangers aren't sure Olt is 100 percent after dealing with inflammation in his right heel for almost all of September. He played on Sunday for the first time in 18 days when he entered Game 2 in the seventh inning when Beltre left with a strained left shoulder. Olt grounded out in his only at-bat and said the heel felt good. But he is not yet a full speed.

"We told him to take it easy until he's comfortable where he is," Washington said. "We kept reminding him to run to your comfort."

Brandon Snyder, who can play multiple positions, and outfielder Leonys Martin are the options if Olt isn't ready. Martin is the more productive player while Snyder offers more versatility. He can play the outfield, both corner positions and catch in an emergency.

MLB to investigate tweet on Holland's account

OAKLAND -- Rangers general manager Jon Daniels said the club and Major League Baseball are looking into who might have posted a homophobic slur on pitcher Derek Holland's Twitter account. The slur was posted during Game 2 of the Rangers' doubleheader against the Angels on Sunday. Holland started the game and was on the bench when the slur was posted.

"I honestly don't know," Holland said. "I know it wasn't myself. I talked to my family and my fiancee. They all said the exact same thing -- it wasn't them. I have no idea. The only thing I know is MLB is taking care of it and they're going to help me out and figure out who it was."

The slur might have been posted by somebody with access to the account or somebody who hacked into it. Major League Baseball prohibits players from using electronic devices from 30 minutes before the game until 30 minutes afterward.

"It's a serious issue, it's an unacceptable term to use," Daniels said. "That's why our first reaction was to go to Derek and MLB. It's not something we're going to sweep under the rug."

Blue Jays shortstop Yunel Escobar was suspended for three games in September after he outlined a similar slur in Spanish with his eye black on his face during a game.

"In case you haven't seen, all I ever do is write like Chuck Norris facts or random facts like, I don't know, a duck, you can't hear it's echo," Holland said. "I do random facts. I don't write anything like that. I haven't messed with the whole Twitter since. Whatever was said was said on there. It has nothing to do with me. I didn't say anything."

Worth noting

• Joe Nathan, with a blown save in Game 1 on Sunday and a successful save in Game 2, was the first pitcher in Rangers history to have both a save and a blown save on the same day. The last Major League pitcher was Cardinals reliever Ryan Franklin on June 5, 2008.

• Nathan said he was available on Monday despite pitching both games on Sunday. Said Nathan, "I'm running on adrenaline right now."

• The Rangers were 15-13 in Septemer, the third straight year they have had a winning record for the month.
