ARLINGTON -- Craig Gentry was called up from Triple-A Round Rock on Saturday even though he had the weakest offensive numbers of their three outfielders. The difference is he is a right-handed hitter, while Endy Chavez and Doug Deeds are left-handed hitters.

The Rangers' three current starting outfielders at the Major League level -- Julio Borbon, David Murphy and Mitch Moreland -- are all left-handed hitters.

"I needed to balance it out," manager Ron Washington said.

Gentry, who replaced the injured Nelson Cruz on the roster, has been an excellent outfield prospect for the Rangers for the past two years and has played 11 games at the Major League level. But he missed the end of last season at Triple-A Oklahoma City with a broken right wrist and was still recovering from that in Spring Training when he suffered a bruised right shoulder running into a wall.

He is healthy again and was hitting .239 with 16 runs scored, no home runs and nine RBIs in 25 games with Round Rock. Endy Chavez, who has spent the past two years recovering from a bad knee injury, is hitting .327 with Round Rock. Chavez also has 827 games of Major League experience and a career .270 batting average.

"We haven't forgotten what Chavez has done," Washington said. "But for this, the fit wasn't there."

Moreland to see bulk of time in right field

ARLINGTON -- Mitch Moreland showed up in Spring Training ready to be the Rangers' everyday first baseman. That's where he has gotten the vast majority of his work, although the Rangers had him play in the outfield on occasion just in case he was needed out there.

He is needed out there. With Nelson Cruz going on the disabled list with a strained right quadriceps muscle Saturday, the Rangers will likely continue to go with Moreland in right field and Chris Davis or Mike Napoli at first base.

Moreland has started the last four games in right, including Saturday against the Yankees, after Cruz left Tuesday's game against the Mariners with what was originally described as tightness in his right quad.

"I'm fine with it," Moreland said. "It's like I said from Day 1, I'll be ready wherever they need me -- first base or right field. It looks like it will be right field, so I will be ready to play."

Moreland is familiar with the position. He played both positions in the Minors and was in right field for 183 games, as opposed to 143 at first base. But the Rangers' need last season when he came up in July was at first base, and he handled the position well enough to be given the job coming into this year.

That's why he concentrated almost solely on first base in Spring Training. But that started changing when Josh Hamilton went on the disabled list on April 13 and Davis was recalled from Triple-A. At that point, Moreland was needed on occasion in the outfield. Now it has become a primary need, and he is relearning the position on the fly with outfield coach Gary Pettis.

"I feel I've done OK," Moreland said. "I could probably get better reads on balls. Sometimes I've looked a little unsure, but that's all going to change with more experience. I feel comfortable out there."

His only error at any position this season was a dropped fly ball in right field in Oakland on Sunday.

"Every time he goes out there, he gets better," manager Ron Washington said. "Gary has spent a lot of time with him, and he's getting better. He is starting to get a feel for the position."

O'Day begins road back from hip surgery

ARLINGTON -- Darren O'Day is back with the Rangers just over a week after undergoing surgery to repair a partially torn labrum in his left hip. O'Day is off crutches, but he won't start throwing for another couple of weeks.

Right now he is doing range of motion and strengthening exercises and is looking at five to seven weeks of recovery time.

"The early results are encouraging," O'Day said. "I'm walking good and feeling good. It's probably been hurting for three to four years, but it got to the point where it was hurting every other pitch, and I didn't know which pitch it would hurt on."

The Rangers finally decided the best thing would be to get the problem taken care of once and for all.

Cody Eppley, another right-handed sidearm reliever, has done well in O'Day's absence. He threw a perfect eighth inning on Friday night and has a 1.35 ERA through five outings entering Saturday. In 6 2/3 innings, he has allowed three hits and two walks with five strikeouts. Opponents are hitting .143 off him.

Rangers select Honorary Bat Girl

ARLINGTON -- The Rangers will honor Dr. Leslie Sewell of Haughton, La., as their Honorary Bat Girl prior to their Mother's Day game on Sunday against the Yankees. She will be part of the pregame ceremonies designed to raise breast cancer awareness in Major League Baseball's partnership with Susan G. Komen for the Cure.

Sewell, a physician and single mother of six children ranging in ages from 7 to 25, began the fight against breast cancer five years ago, when she had a double mastectomy. Since that time, she has had five more surgeries, as well as chemotherapy and radiation while continuing to practice as a physician.

Today, she raises funds and awareness for breast cancer prevention and treatment by participating in a number of events, including a half-marathon and walks. Sewell and her family are big Rangers fans and attend several games in Arlington every year.

On Mother's Day, hundreds of MLB players are expected to use pink bats by Louisville Slugger stamped with the MLB breast cancer awareness logo. To further demonstrate their support for the breast cancer cause, players and on-field personnel will wear the symbolic pink ribbon on their uniforms along with pink wrist bands.

Commemorative dugout lineup cards also will be pink. Game-used Louisville Slugger pink bats from Mother's Day games will be auctioned exclusively on MLB.com at a later date to raise additional funds for Susan G. Komen for the Cure.

Briefly

• Mike Napoli's pickoff of Russell Martin at third base on Friday night was the first by a Rangers catcher since Gerald Laird on July 24, 2007, against Seattle.

• The Rangers went into Saturday's game working on a streak of five straight quality starts from their starting pitchers. But they were 1-4 in those five games, with the only victory coming from C.J. Wilson.
