Notes: Catalanotto placed on DL

Diaz called up from Triple-A to take outfielder's roster spot

ARLINGTON -- The Rangers placed Frank Catalanotto on the disabled list on Tuesday with an acute strain of his right biceps muscle and called up Victor Diaz from Triple-A Oklahoma to fill the roster spot.

Diaz was in Tuesday's lineup as the Rangers designated hitter and cleanup hitter because manager Ron Washington wanted to give Sammy Sosa a day off and he didn't want move any other hitters out of their normal spots in the order.

"He can hit there," Washington said of Diaz. "He's not going to keep the bat on his shoulder and if they throw the ball in the wrong spot; he'll be swinging."

Catalanotto underwent an MRI, and the news was good. He was afraid that he might have torn a muscle and would need surgery, but the results found only inflammation, which can be taken care of with exercise and medication. Catalanotto may require a cortisone shot, but the Rangers still hope that he'll return by the minimum of 15 days or shortly thereafter.

"I was pleasantly surprised," Catalanotto said. "I had a tough time sleeping last night because I had so many things going through my head. I finally went in and got the news, and I'm happy."

Diaz was hitting .356 with three home runs and 28 RBIs in 23 games for the RedHawks, a huge improvement over his Triple-A numbers at Norfolk in the Mets organization last season, when he played in 103 games and hit .224 with eight home runs and 38 RBIs.

"It was going well," Diaz said. "I was seeing good pitches, being patient and driving the ball. Instead of worrying why I wasn't in the big leagues, I let my game do the talking. The last three years, I was on the Mets' Opening Day roster and kept getting sent down. It would frustrate me, and in my mind, I was thinking, 'I've got to get back to Shea.' I was overaggressive. The ball wasn't even out of the pitcher's hand, and I was already lunging."

Washington gave Sosa Tuesday off because he recently played four games on Toronto's artificial turf, and the players didn't get back to their homes in Texas until after 4 a.m. CT on Tuesday.

"He's the elder statesman, so he gets the day off," Washington said.

Wood up, Feldman down: The Rangers made a second roster move on Tuesday, sending pitcher Scott Feldman to Triple-A and calling up Mike Wood. The Rangers wanted to make sure they had a long reliever for the Yankees series, because Willie Eyre, who pitched three innings on Sunday, is unavailable for one or two days more.

"You never know what's going to happen, but these guys can swing the bat," Washington said. "We wanted to make sure we had some fresh arms."

Wood was 2-0 with a 2.05 ERA in four games for Oklahoma. Feldman was sent down with a 6.08 ERA, and opponents were hitting .309 off him.

"It's never fun, but there's nothing I can do about it except pitch better," Feldman said. "I started off throwing the ball pretty well, but the last few times, I've had trouble with my command. I don't throw 97 mph, so I have to get ahead of hitters and use it to my advantage."

Pink bat day: The Rangers are going with the pink bats for Mother's Day on May 13. Equipment manager Zack Minasian said that pink bats have been ordered for all position players to be used on Mother's Day to raise awareness for breast cancer.

"They'll all get pink bats," Minasian said. "It's up to them if they want to use them, but the opportunity is there."

After Mother's Day, the bats will be put up for auction to raise money for breast cancer awareness. The Rangers planned to use pink bats on Mother's Day last year, but their game in Boston was rained out.

"I think most of our guys will use it," shortstop Michael Young said. "It's for a good cause."

He said it: "It's not a surprise. Alex is one of the most gifted players in the Majors. I'm not shocked all -- he's that good." -- Young, on former Rangers teammate and current Yankees third baseman Alex Rodriguez

Monday's Minor stars: Below are the top performances from Monday's Minor League games:

Gold: John Mayberry hit a three-run, walk-off home run in the ninth inning to give Bakersfield an 8-6 win over Lancaster. Mayberry went 2-for-5 with four RBIs.

Silver: Clinton starter Omar Poveda allowed two runs on two hits -- both solo home runs -- while walking one and striking out 12. The game went into extra innings, but Clinton lost, 3-2, in 12 innings.

Bronze: Frisco starter Armando Galarraga went 6 1/3 innings, allowing two runs on five hits and a walk, striking out six. He didn't get the decision, but the Roughriders won, 4-3.

Briefly: The Rangers gave up 35 home runs in April, tying for the second-most April homers allowed in Rangers history. Only the Devil Rays gave up more, allowing 36. The Rangers allowed 43 home runs in April 2001. ... Kenny Lofton's 11 April stolen bases were tied for the second most by a Rangers player in April. Cecil Espy stole 13 in April 1989, and Tom Goodwin stole 11 twice.

Up next: Right-hander Robinson Tejeda will face left-hander Andy Pettitte and the Yankees at 7:05 p.m. CT on Wednesday in the second game of the three at Rangers Ballpark in Arlington.
