MILWAUKEE -- Despite mounting legal troubles regarding his alleged use of performance-enhancing drugs, Roger Clemens apparently hasn't decided whether he will retire, one of his former owners told MLB.com on Thursday.

The right-hander, who will be 46 years old on Aug. 4, is an unsigned free agent, but missed the first few months of the season the past two years before returning to action. Drayton McLane, the chairman and chief executive of the Astros, said he spoke with Clemens briefly at a game in Houston as recently as three weeks ago.

"We have a personal services contract with him and it's not activated until he tells us he's ready to retire," said McLane, just after this week's quarterly owners' meetings drew to a conclusion. "Well, he hasn't said that. I think if he was ready to retire, and that was clear, he would have already said that to us. But that has not happened."

Clemens, a seven-time winner of the Cy Young Award, pitched for McLane's Astros from 2004 to 2006 before returning to the Yankees for one last fling in 2007. During that stay with his hometown team, Clemens signed a 10-year personal services contract with the Astros that McLane says he intends to honor.

Clemens, who ended last year with 354 wins and is second on the all-time list with 4,672 strikeouts, is being investigated by the FBI and IRS for possibly lying under oath abut his alleged drug use to a Congressional committee at a hearing on Feb. 13.

He also is involved in an defamation civil lawsuit against his former trainer, Brian McNamee, who is cited in the Mitchell Report as having injected Clemens with steroids and human growth hormone on numerous occasions from 1998 to 2001. Clemens has said that he never used performance-enhancing drugs.

Finally, Clemens recently made a public apology after stories emerged that he had had a string of extra-marital affairs during his playing days.

McLane said Clemens is waiting to resolve his legal troubles before determining what to do about his future.

"That doesn't mean he's going to pitch, he's just undetermined and wants to see where all this is going," McLane said. "His legal stuff, I think he wants to see how that unfolds."

McLane wouldn't dismiss the possibility of re-signing Clemens. He said he also wants to allow events to unfold before determining whether he might bring him back for another tour with the Astros.

"Would we? We're not even ready to think about that yet," McLane said. "We've got to wait and see what happens. Right now we're not focusing on it at all. We're just going to have to go further down the road and see what unfolds. There are lots of issues out there."
