Hal Steinbrenner is on the hook for $114 million over the next five years to Alex Rodriguez, so the third baseman’s most recent alleged ties to performance-enhancing drugs have caught the attention of the Yankees owner.

“It’s a concern, but it’s out of our hands,” Steinbrenner said yesterday at the Yankees’ minor league complex. “We will cooperate with MLB any way we can, in any way we’re asked to, but other than that, there’s not much to say. I don’t know any more than you do.”

The league is investigating Biogenesis, an anti-aging clinic in Miami, after the Miami New Times obtained documents containing names of numerous players including Rodriguez, and whether its owner, Anthony Bosch, provided banned substances.

Rodriguez, through spokesmen, has denied any connection with Bosch or the clinic.

But these days, Rodriguez’s future is just one of many uncertainties surrounding the Yankees.

After an offseason in which the organization devoted considerable funds to 2013, but not much beyond that, questions remain about what the payroll is going to look like going forward.

Steinbrenner did say yesterday there is an interest in signing Robinson Cano, a free agent after this season, to a long-term deal.

“There’s been a conversation or two, but we’ll get into that at a later date,” Steinbrenner said. “He’s obviously been a great Yankee and I hope he’s here his entire career.”
