Hal Steinbrenner is concerned about the latest drug allegations involving Alex Rodriguez, but says the matter is being looked at by Major League Baseball.
The Miami New Times reported late last month that Rodriguez bought HGH and other performance-enhancing substances in recent years from Biogenesis of America LLC.
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."
