Roger Clemens will make his decision on whether or not he will return to action by June 15.

The Astros, the Yankees, the Boston Red Sox and the Texas Rangers have expressed interest, with the Astros considered the favorite.

Andy Pettitte, one of Clemens's best friends, said he hoped he would return to Houston. "I think he'll come back," Pettitte said. "I still talk to him. He hasn't said yea or nay, but I think he wants to come back."
