Notes: McCarthy to miss next start

Rangers righty has blister on pitching hand; Redman signed

OAKLAND -- John Koronka will take Brandon McCarthy's spot in the rotation and pitch on Wednesday against the Oakland Athletics.

McCarthy is being scratched because of a blister on his right middle finger, a problem that forced him out of Friday's start against the Boston Red Sox after just two innings. McCarthy tried to throw in the bullpen on Sunday but had to shut it down because the finger was still bothering him.

"Not good," McCarthy said. "It was bugging me, but more than anything, the anticipation was changing the way I throw and that was irritating the rest of the body. You don't want to aggravate anything else."

The finger is causing a tender burning sensation and pitching coach Mark Connor said, "You can't pitch with it like that."

Koronka made one start for the Rangers on May 19 against the Houston Astros and allowed three runs in five-plus innings in a 6-1 loss. He was optioned back to Triple-A Oklahoma after that game and beat Iowa in his last start, allowing three runs in seven innings. He is 4-3 with a 5.20 ERA for the RedHawks.

Koronka will follow Mike Wood, who was recalled from Oklahoma on Monday and will start Tuesday against the Athletics. Koronka will replace McCarthy on Wednesday for one start, and then the Rangers are expecting to activate Kevin Millwood off the disabled list.

Millwood is expected to follow Wood, Koronka and Vicente Padilla in the rotation and pitch Friday against the Seattle Mariners. Kameron Loe will be pushed back to Saturday. The Rangers, who are off Monday, are hoping McCarthy can return to the rotation on June 9 against the Milwaukee Brewers.

Millwood, on the disabled list for the second time because of a strained hamstring muscle, pitched five scoreless innings for Double-A Frisco on Sunday. He allowed one hit and one walk while striking out three.

"It went well," Millwood said. "I was able to throw all my pitches and get my pitch count up. My leg felt good. All in all it was a good day."

To make room for Wood, the Rangers optioned reliever Scott Feldman to Oklahoma. Feldman was 1-2 with a 6.97 ERA in 17 games.

Rangers sign Redman: The Rangers have signed pitcher Mark Redman to a Minor League contract and assigned him to Oklahoma. He will start for the RedHawks on Tuesday.

Redman, 33, was a 14-game winner for the 2003 world champion Florida Marlins and an All-Star with the Kansas City Royals last year. He had trouble getting a job this offseason before finally signing with the Atlanta Braves but was released after going 0-4 with an 11.63 ERA in six games, including five starts. The Rangers agreement is that he'll pitch for Oklahoma for a month and then be reevaluated.

"We're just looking for pitching depth, and we want to give Mark a chance to come back," general manager Jon Daniels said. "We'll see how he pitches down there and whether he can help us."

Wright headed to Oklahoma: Jamey Wright, who has been sidelined since the start of the season with shoulder inflammation, will be assigned to Oklahoma on medical rehabilitation assignment and pitch Thursday.

He could be two starts away from being an option at the Major League level. He'll likely throw 75 pitches on Thursday and then 85-90 in his next start. After that, it will depend on how well he's pitching. But Connor received a good report on Wright's last outing at extended Spring Training from Minor League pitching instructor Keith Comstock.

"He was very complimentary about his stuff, "Connor said. "I asked if [Wright] could get Major League hitters out with that stuff, and he said yes."

Sosa gets day off: Sammy Sosa was out of the lineup on Monday after playing three straight games in the outfield against the Boston Red Sox. Manager Ron Washington said he expects Sosa back in the lineup on Tuesday, possibly at designated hitter. The Rangers are hoping that Frank Catalanotto will finally be fully recovered from his biceps tendinitis and will be ready to play the outfield.

With Sosa out of the lineup, Washington moved Michael Young back into the No. 3 spot and Mark Teixeira into the No. 4 spot. Ramon Vazquez, who was hitting .458 going into Monday's game, was in the No. 2 spot.

"I didn't have a No. 4 hitter," Washington said. "That was the only way I could set up the lineup."

He said it: "There are some things we need to do and we're in the process of doing that. It's not happening as fast as we'd like to, but we're trying to change that. If it doesn't happen as fast as the people want it to happen, I probably won't have a job. But I'm not worried about that." -- Washington

Sunday's Minor stars: Top performances from Sunday's Minor League games:

Gold: Class A Clinton right-hander Omar Poveda threw seven scoreless innings in the LumberKings' 6-0 victory over Burlington. He gave up two hits, walked one and struck out eight, raising his record to 5-1 with a 2.01 ERA.

Silver: Oklahoma's Jason Botts was 2-for-3 with an RBI in an 8-1 loss to Iowa. He is now 19-for-42 (.452) with 16 RBIs in his last 11 games. He has 40 RBIs in the RedHawks' first 49 games.

Bronze: Jim Fasano's home run in the eighth inning gave Double-A Frisco a 2-1 victory over Tulsa for the Roughriders' eighth win in their last 10 games.

Briefly: Outfielder Brad Wilkerson (strained hamstring) reported to Oklahoma on Monday to begin a medical rehabilitation assignment and Jerry Hairston (pinched nerve) is expected there on Tuesday. Hairston could be activated by Friday, but the Rangers have no timetable on Wilkerson. ... Ron Mahay, in Oklahoma on a rehab assignment, is expected to pitch on Tuesday. ... John Rheinecker threw five scoreless innings for Oklahoma on Saturday, and word is he could be an option if the Rangers need a reliever. But he probably needs at least two more starts before he could be an option for the rotation.

Up next: Right-hander Wood pitches for the Rangers at 9:05 p.m. CT Tuesday against the Athletics at MacAfee Coliseum. Left-hander Lenny DiNardo will go for the Athletics.
