White Sox center fielder Alejandro De Aza will play for the Dominican Republic in the World Baseball Classic.

De Aza will replace the Brewers' Carlos Gomez, who declined an invitation.

"I'll just try to get as much work in here to be ready," said De Aza, who leaves for Miami on March 3.

Beckham's stance: Gordon Beckham will continue to employ a crouch at the plate that he started using in September.

"This allows me to square more balls, and that's what happened in September," Beckham said. "I got down there further and I saw the pitches better and was able to put better swings on them."

Thornton throwing: Reliever Matt Thornton played catch Thursday morning and does not believe his recent bout of tendinitis in his left triceps will prevent him from being ready by opening day.

"If April 1 comes in jeopardy, believe me, you guys would know," Thornton said. "I would be worried then."

Thornton plans to throw batting practice Saturday and make his exhibition debut March 5. He described the MRI on his elbow Tuesday as "over-the-top precautionary."
