Roger Clemens is ready to join the Houston Astros -- as a consultant. In a sign that Clemens' pitching career could be over, his agent told the Astros on Wednesday that the seven-time Cy Young winner is set to start his personal-services' contract with the team. "He's moving toward retirement and leaving open the possibility of playing," agent Randy Hendricks said. "As Roger has stated several times, he's failed at retirement repeatedly."
