Martin departs in ninth after outfield collision

X-rays negative on center fielder's sprained right ankle

CHICAGO -- Rangers center fielder Leonys Martin exited Saturday's game in the ninth inning with a sprained right ankle after colliding with left fielder David Murphy in the Rangers' 3-2 loss to the White Sox.

Precautionary X-rays were negative following the game.

"We'll know more [Sunday]," Rangers manager Ron Washington said. "It wasn't too serious, hopefully, because he tried to walk on it and it felt sort of good. He was going to try to stay out there, but we weren't going to let that happen."

Martin and Murphy ran into one another when White Sox first baseman Paul Konerko hit a soft fly ball to left-center. Murphy ended up catching the ball and, while he was doing so, Martin tried to sidestep out of the way and appeared to twist his ankle while falling to the ground.

He was helped off the field by trainers, though had to momentarily pause midway through the trek back to the dugout.

"It looked like it was hit perfectly in between us and, if he calls the ball, then he has priority and I'm supposed to back off and let him have it," Murphy said. "But it was such a late-developing play that by the time I heard him call it, the ball was probably close to in my glove.

"I feel if I pull away from it then, it might be one of those plays where the ball doesn't end up finding anybody's glove and you don't make an out. So I felt like at that point I just had to stay with it."

With Martin leaving the game, right fielder Alex Rios moved to center, while first baseman Mitch Moreland shifted to right field. Adam Rosales replaced Moreland at first.

Tepesch set for Minors rehab start

CHICAGO -- Right-hander Nick Tepesch threw live batting practice before the Rangers-White Sox game on Saturday at U.S. Cellular Field and was green-lighted for a Minor League rehab start.

Tepesch, on the disabled list since July 6 with right elbow inflammation, will throw 35-40 pitches for Double-A Frisco on Tuesday.

"No pain," Tepesch said following his 43-pitch session. "That's really the biggest thing. Just continue to go forward."

The Rangers will determine the next step following the right-hander's start at Frisco.

In other rehab news, right-handed reliever Alexi Ogando (right shoulder inflammation) felt fine after throwing from 60 feet on Saturday.

Berkman's return still unknown to Rangers

CHICAGO -- The Rangers continue to hold out hope that Lance Berkman can help the American League West leaders in some capacity this season, but there is still no word on when the 15-year veteran will return to the field.

One thing the Rangers would like to do, however, is give Berkman some reps in the Minor Leagues before he returns, but the Minors season ends in early September.

If that isn't an option, Rangers manager Ron Washington said Saturday at U.S. Cellular Field that he would have no issues sending Berkman -- on the disabled list since July 7 with inflammation in his left hip and a chronic sore right knee -- to the plate.

"Hopefully, we've got somewhere we can get him some at-bats," Washington said. "If not … he knows what he's doing."

For now, Berkman will continue his rehab work in hopes of a return.

"Hopefully, he's ready to go for us [by Sept. 1 when the roster expands] and help us as we move down the stretch," Washington said.

Worth noting

• Rangers general manager Jon Daniels turned 36 on Saturday.

• When the Rangers hit a pinch-hit home run and an inside-the-park home run during Friday's 11-5 win over the White Sox, it was the first time in franchise history the club had accomplished both feats in the same game. Texas was also the first Major League team to do so since San Francisco on July 4, 2010, and the first American League team since Kansas City on May 27, 1997, according to STATS, Inc.
