TAMPA, Fla. -- Alfredo Aceves has decided to withdraw his name from consideration for Mexico's World Baseball Classic roster, instead choosing to remain in camp with the Yankees.

"This is my job," Aceves said Sunday. "I cannot leave my job. I have to have a job first. I want to make my team and help the team."

Aceves, 26, made his Major League debut with New York last season, appearing in six games (four starts) and going 1-0 with a 2.40 ERA. The right-hander enters Spring Training in consideration for the Yankees' vacant role as a long reliever and spot starter.

"I want to throw my bullpens with [Jorge] Posada and [Jose] Molina, because these guys are going to be here all season with us," Aceves said. "I want to know how they work and show them how I work."

Aceves was listed on Mexico's provisional roster for the Classic and expressed interest in pitching for his country, but he decided it is more important for him to secure a Major League job.

"Seriously, I wanted to pitch," Aceves said. "It's my country and the first time they invited me. This year, I said, 'I want to go,' but I can't now."
