Astros general manager Jeff Luhnow is not yet ready to anoint Brandon Lyon as the team's closer next season. "Lyon has experience and a lot of the closer role really is about having experience in those pressure situations,'' Luhnow said. ''No matter what, whether it's the ninth, eighth or seventh inning, he will play an important role because of his veteran presence." Lyon, who is owed $5.5 million next season, appeared in 15 games before undergoing surgery in June to repair a detached right biceps tendon and a torn labrum. Earlier this month, the Astros may have selected a closer candidate in Rhiner Cruz with the first pick of the Rule 5 Draft. Cruz was clocked at 98 mph last spring, but has struggled with his command.
