Rangers may get Feliz, Tepesch back by September

ARLINGTON -- Rangers general manager Jon Daniels is hopeful to get right-handers Neftali Feliz and Nick Tepesch back sometime in September.

Feliz is dealing with triceps tendinitis in his rehab assignment. He's listed as day to day, and is expected to throw a bullpen session on Thursday. Daniels said Feliz and the club are not concerned by the injury.

"It's a Spring Training type deal, a little soreness in his triceps," Daniels said. "He doesn't feel it at all when he's playing catch. When he ramps up and throws with velocity when he's in a game, that's when he felt it a couple times."

The Rangers were hoping to get Feliz back by the end of August, but that's unlikely with this setback. Feliz has made three appearances during his rehab assignment, two in the Arizona Rookie League and his last with Triple-A Round Rock. He has pitched 2 2/3 scoreless innings with four strikeouts and four walks.

Tepesch could return around early September, as he's now throwing at 120 feet. He was placed on the 15-day disabled list with right elbow inflammation on July 7.

Lewis to undergo hip surgery

ARLINGTON -- Colby Lewis will undergo right hip resurfacing surgery next week in New York. The surgery is an alternative to hip replacement surgery, where the ball of the hip isn't replaced. Lewis had about five bone spurs in the hip, and the doctors told Lewis he wouldn't receive the range needed if they just cleaned the bone spurs.

"It's not a full reconstruction, but it's basically more dealt for active lifestyles," Lewis said. "This is the point that it's come to."

The procedure will be done by Dr. Ed Su, who told Lewis he should be ready to go in six months. Lewis said Su's patients can walk a mile seven days a week after the surgery.

"I really haven't talked to him [about] what that's going to entail, or where I'm going to be at, or how much exact pressure I'm going to be able to put on it in three or four months," Lewis said. "The first couple months is getting you up, getting you moving and walking around. The 1-3 month period is where you develop a lot of your strength back, and the bone is adhering to the replacement and go from there."

Lewis expects to get on a mound in four months and begin normal activities. He will be a free agent at the end of the season.

"I knew I was going to have it replaced at some point in my life," Lewis said of his hip. "Right now, I wasn't really hoping on it, but it's something to give me my best opportunity to come back and be pain free. Now that I've made the decision, it's something I'm looking forward to being pain free."

Suspended Cruz to train in Dominican Republic

ARLINGTON -- Nelson Cruz will fly to the Dominican Republic on Wednesday and stay for 12 days to train at his home, and at the Rangers' facility in Boca Chica. Cruz, currently serving a 50-game suspension, has been in touch with the club's conditioning staff to discuss his program.

Rangers general manager Jon Daniels reiterated the club has not made any decision on whether Cruz would be on the postseason roster. Right now, they just want to keep Cruz in the best baseball shape possible.

"First of all, we have to get there," Daniels said of the postseason. "We're not going to get ahead of ourselves. We've got to get there first to have the conversation. At that point, there's a lot of factors. What kind of shape is he in? How's the team playing? How's the team gelling? How are our other guys preforming?"

Cruz will likely only be able to simulate a game in the instructional league in Arizona if the Rangers would like him back for the postseason.

Rosales back with his new, old team

ARLINGTON -- Adam Rosales reunited with his old team before Tuesday's game. That would be the Rangers this time, not the A's. The utility infielder was claimed by Texas for a second time in a 10-day span on Monday. He was designated for assignment twice by the A's and once by the Rangers in that stretch.

"It's like I got sent down to Round Rock and came back," Rosales said. "It's like I never left.

"It's an experience not many people go through. I feel like I have the personality and the character to do it. Every time I get back on the field, I feel like I'm where I need to be. You have a lot of waiting around, especially the role I'm playing, so I've got to be patient. I'm really testing my patience."

Engel Beltre was optioned to Triple-A Round Rock to make room for Rosales' return with the Rangers. Rosales was active for three games in his first stint with Texas, when he was designated for assignment due to Nelson Cruz's suspension. The Rangers went with a platoon strategy in right field to makeup for Cruz's absence until they acquired Alex Rios last weekend. Rosales gives the club a backup infielder with the departure of Leury Garcia in the Rios trade.

"We wanted him when we claimed him the first time," Rangers manager Ron Washington said. "We were just hoping no one would claim him when we put him back out there.

"Him not playing for a while isn't an issue, because that's what he did. He didn't play for a while."

Rosales shipped his items and his car to Texas a week ago, when the club claimed him the first time. He left it in Texas with the uncertainty of his situation with the A's, who eventually designated him for assignment again.

"We just figured that the Rangers showed interest in me last time," Rosales said. "If they showed interest again, then this is where I'll be. I made a good judgement call there by not panicking and having it shipped, because it'd probably just get to Oakland and we wouldn't have a car."

Worth noting

• The Rangers honored Washington before Tuesday's game for becoming the all-time wins leader among managers in club history. He recorded his 582nd win on Sunday at Oakland, surpassing Bobby Valentine.

Joe Nathan recorded his 35th save on Monday, giving him eight seasons with 35 or more. That is the third most in baseball history, behind Trevor Hoffman and Mariano Rivera.

• This is the third season the Brewers and Rangers have met in Interleague Play since the Brewers moved to the National League in 1998.
