Yankees managing general partner Hal Steinbrenner says he's concerned about the latest drug allegations swirling around third baseman Alex Rodriguez, but that the matter is being looked at by Major League Baseball.

The Miami New Times reported late last month that the three-time AL MVP bought human growth hormone and other performance-enhancing substances in recent years from Biogenesis of America LLC, a now-closed clinic in Coral Cables, near Rodriguez's offseason home.

Speaking on Friday at the Yankees' minor league complex, Steinbrenner said the situation is "a concern, but it's out of our hands."

"We will cooperate with MLB in any way we can, any way we're asked to," he said. "But other than that, there's not much to say. I don't know any more than you do."

Rodriguez has denied the allegations. He admitted four years ago that he used PEDs from 2001-03.

The Yankees signed one-time Boston Red Sox third baseman Kevin Youkilis to fill in for Rodriguez, who is sidelined for at least the first half of the season after hip surgery Jan. 16.

"I've always liked Kevin," Steinbrenner said. "He always seemed like a good leader, a hard worker and a very enthusiastic - loves the game - kind of guy. And that's the kind of guy we want."

Steinbrenner feels the Yankees have a "championship-caliber team" this season.
