CHICAGO -- Brandon McCarthy, who has been sidelined since April 24 with a stress fracture in his right shoulder blade, is close to being activated from the disabled list to Triple-A Oklahoma City.

He could be used as a reliever instead of a starter. McCarthy was 1-0 with a 2.51 ERA in four starts with Oklahoma City before he went down, but assistant general manager Thad Levine said that the Rangers are likely to discuss the possibility of moving him to the Oklahoma City bullpen.

"We want to give ourselves as much flexibility as we can to see if it gives him an opportunity to help us at the Major League level," Levine said. "One of the strengths of the organization is our Major League-ready pitching depth, and he is part of our depth."

McCarthy has made 56 starts and 54 relief appearances at the Major League level. But he has made 44 starts and only one relief appearance for the Rangers.

Guerrero appears All-Star bound

CHICAGO -- The last time Vladimir Guerrero went to the All-Star Game, he ended up winning the Home Run Derby. That was in 2007 in San Francisco.

Guerrero is not interested in doing it again this time around in Anaheim.

"No way," Guerrero said when asked if he would participate the Home Run Derby this year. "In '07, the last time I did it, I went on a streak without hitting a home run after doing it. That's the reason."

Guerrero is likely to be in Anaheim. He remains the leader among American League designated hitters in the latest fan balloting update released on Tuesday. Guerrero went into Tuesday's game against the White Sox hitting .332 with 12 home runs and 44 RBIs in 49 games.

"It feels good. It shows I have been doing a good job," Guerrero said. "I haven't been there for a few years, so it would be something."

Guerrero said it's not a big deal to him that the game is being played in Anaheim. He still owns a house there. He played for the Angels from 2004-09, but he's looking forward more to the Rangers' first trip back to Anaheim between June 29-July 1.

"It will be interesting to see the fans' reactions since I left," Guerrero said.

Strop ready to contribute to Rangers

CHICAGO -- Pedro Strop joined the Rangers on Tuesday when Derek Holland was officially placed on the disabled list with inflammation in his left shoulder. Strop was pitching extremely well at Triple-A Oklahoma City, with a 1.74 ERA and five saves in 17 games. He finished with an 11-inning scoreless streak in which he allowed just one hit. In 20 2/3 innings, he allowed 14 hits and six walks while striking out 24.

Strop was 6-6 with a 5.06 ERA in 47 relief appearances for Double-A Frisco and Triple-A Oklahoma in 2008 while recovering from a fractured right elbow that forced him to miss most of 2007.

"I think consistency is the thing that's really helped me," Strop said. "I'm consistently commanding the ball with my secondary pitches, throwing them for strikes.

"Last year, I was coming back from the injury and worried about velocity more than command. This year, I'm not worried about velocity, I'm making my pitches where I want them. That's made me a better pitcher. I'm pitching. I'm not throwing."

Strop, who made seven appearances for the Rangers last year, was called up on May 15 but with the Rangers for only one day before being sent back to Oklahoma City. He didn't appear in a game. He will likely be with the club until Saturday, when the Rangers are expected to call up Tommy Hunter to replace Holland in the bullpen.

Soreness not hindering Saltalamacchia

CHICAGO -- Triple-A Oklahoma City catcher Jarrod Saltalamacchia has had some lower back soreness lately. But it has not impacted his throwing, and the reports continue to be good out of Oklahoma City.

Outfielder Endy Chavez is still in extended spring training, trying to come back from knee surgery from a year ago. Chavez, a veteran of 827 Major League games who signed a Minor League contract at the beginning of Spring Training, hasn't played in a big league game since tearing his ACL in the right knee on June 19 last year. Chavez has had difficulty playing in back-to-back extended spring training games without coming down with soreness in his knee.

Catcher Toby Hall, another veteran coming back from surgery, is also still in extended spring training and not close to being an option at the Major League level. Hall is still building strength in his surgically repaired right shoulder and is not yet playing full games behind the plate.
