Beltre may face offseason surgery

SEATTLE -- The unknown source of Adrian Beltre's stomach discomfort is believed to be the result of a buildup of scar tissue from an appendix surgery 12 years ago and it may require surgery after the season. The Rangers third baseman's availability the rest of the season should not be in jeopardy, but will depend on Beltre's pain tolerance.

Beltre had stayed in Anaheim to undergo tests on his stomach while his Ranger teammates traveled to Seattle for Friday's series opener. He was in the lineup on Saturday at third and hitting fourth.

"The doctor told me that he's 90 percent sure what's causing the pain is scar tissue from my old surgery, appendix," Beltre said. "It's growing over the years and it's kind of pushing on my intestines.

"He said that if [it] stays the same or gets worse, we're going to have to do a little procedure."

That said, Beltre was confident he would get through the season. Prior to Saturday's game, he said he physically felt much better than the past couple of days. Although there are no medications to help disperse scar tissue, Beltre said eating healthy could help.

Rangers skipper Ron Washington said he "may have to DH him a little more than I want to," but that would be the biggest change he'd make from a managerial perspective.

"He can play to whatever he can tolerate," Washington said. "The old saying I always bring up, 'Mind over matter,' and he's got a powerful mind. His stomach issue, don't matter."

Washington keeps confidence in Ogando

SEATTLE -- Rangers reliever Alexi Ogando has pitched just twice in the past nine days and gave up a combined three runs in those relief outings, including a two-run home run in Friday's 6-3 loss in Seattle.

The right-hander has recently dealt with soreness in his biceps, but Rangers manager Ron Washington said as long as Ogando's healthy, he wouldn't shy away from using him.

"[If the] opportunity presents itself, as long as he can take the ball, we are going to give it to him," Washington said. "I think that's going to help everything. I certainly can't predict if that's going away or that's going to flare up again. I don't know."

Washington said any pitcher, especially a reliever, needs consistent work, if possible, to stay sharp. That is what the Rangers will be looking to give Ogando the rest of the season -- consistent work.

Meanwhile, Koji Uehara has been pitching well, making him interchangeable with Ogando, in Washington's mind.

"Say, if we had to use Ogando for a couple innings and then tonight a situation came up, I'll give it to Koji," Washington said. "Say, if Ogando and Mike Adams are not available and a situation come up in the eighth inning, I'll give to Koji. [Robbie] Ross, too."

Washington polishing plans for Napoli

SEATTLE -- Mike Napoli, who recently came off the disabled list after a left quad strain, received two days off prior to starting Saturday behind the dish for the Rangers. As far as Sunday, manager Ron Washington wants to wait and see before slotting a catcher into the lineup.

Washington doesn't believe he has to make a conscious effort to get Napoli, who missed 33 games with his quad injury, a certain amount of starts behind the plate during the remainder of the season. Geovany Soto did the majority of the catching in Napoli's absence.

Napoli could appear in games as the designated hitter, but most likely will not appear at first base, where he has played in 24 contests.

"When I was playing him at first, I really didn't have it totally covered," Washington said. "Now, I got it covered. He just has concentrate on catching and hitting."

Worth noting

• Washington said he'll continue to give Craig Gentry the bulk of time in the outfield while Josh Hamilton deals with a sinus issue. Leonys Martin is also an option, but Washington considers Gentry a more reliable defensive option.

• The Rangers pitching staff enters Saturday's contest with 1,175 strikeouts, six shy of the club record set in 2010.
