ARLINGTON -- Triple-A pitcher Brandon McCarthy, who had just returned from the disabled list last week, is back on it with inflammation in his right shoulder.

He received a cortisone injection Thursday and will be placed on the seven-day disabled list.

McCarthy was placed on the DL the first time on April 24 with a stress fracture in his right shoulder blade. He made his first appearance after coming back on June 3, pitching a scoreless inning of relief and picking up the win. He also pitched a scoreless inning on Saturday against Omaha.

In six games this season with four starts for Oklahoma City, McCarthy is 2-0 with a 2.35 ERA and 19 strikeouts in 30 2/3 innings.

Holland feels fine after short 'pen session

ARLINGTON -- Rangers pitcher Derek Holland said he felt fine a day after cutting short a bullpen session because of shoulder pain.

Holland, who went on the disabled list with left rotator cuff inflammation on June 1, threw only 17 of 30 pitches in that first session since going on the DL.

"I feel good. It was just one of those things that was just precautionary," Holland said. "It wasn't anything to get too worried about."

Rangers manager Ron Washington isn't concerned, either.

"It wasn't bad. As soon as he said he felt something, they just shut him down for precaution," Washington said. "We've got to be very cautious with him. We'll just continue to work him and see how soon it comes back. But concerned? I'm not concerned. It's just a setback."

Holland will throw again Friday, and Washington said there are no plans to do an MRI. Holland was 2-1 with a 4.19 ERA in 19 1/3 innings with five starts before the injury.

Cruz runs bases, feels slight pain in leg

ARLINGTON -- Rangers outfielder Nelson Cruz ran the bases before Thursday's game against the Mariners as he continues his rehab while on the disabled list.

Cruz, who went on the 15-day DL after straining his left hamstring in late May, said he felt a slight pain in the back of his leg but still feels fine overall.

"I ran today and I feel pretty good," Cruz said. "I still feel a little bit [of pain] behind my knee where the tendon is tight. We're going to push it back a couple more days."

He said that it only hurts when he runs and not when he bats. Cruz feels he's strong enough to play, but still wants to take the necessary precautions.

"I can perform. I don't have to be 100 percent," Cruz said. "But I want to make sure I'm 100 percent so I don't go back on the DL.

"I'm going to go in whenever I feel ready. Hopefully, that's next week. But when I feel ready to go, I'm going to go. I don't feel pressure to get back.

Rangers manager Ron Washington said Cruz will do some agility work Friday and hopes to have him back later next week.

Rangers set to use Vladdy in outfield

ARLINGTON -- With the Rangers beginning a stretch of three consecutive Interleague series on the road Friday, manager Ron Washington is preparing to use designated hitter Vladimir Guerrero in the outfield.

Washington said Guerrero will play the field on Friday and Sunday against the Brewers before using him Tuesday and Thursday against the Marlins.

He said he'll make a decision on how to use him in the Astros series later next week.

"The only disadvantage we got is we have eight hitters instead of nine that we're used to," Washington said.

Guerrero entered Thursday second in the American League in RBIs with 51 and fifth in batting average at .336.

He's started four games in the outfield this season, accumulating 35 innings and recording eight putouts.

Bench coach Moore happy to see son drafted

ARLINGTON -- Rangers bench coach Jackie Moore couldn't have been more excited to see his son drafted by the club on Wednesday.

Johnathon Moore, a catcher from Houston-Baptist University, was taken by the Rangers in the 45th round of the 2010 First-Year Player Draft.

"I had the same dream 53 years ago and had the opportunity to play baseball," Moore said. "It's been all my life, it's what I love to do. He's been presented with the same opportunity, and I hope things work out for him. They sure worked out for Dad."

The younger Moore had a solid season behind the plate for the Huskies, batting .355 with six home runs and 51 RBIs.

"The bottom line is he has some ability. He can play," Jackie Moore said. "He has a big heart. ... He grew up in a baseball life and that's what he wants to do. I think with a lot of hard work and dedication and his ability, good things will happen for him."

Moore hopes that his son is able to use the baseball bloodlines he carries into a successful professional career.
