Astros reliever Brandon Lyon  had surgery to drain a small cyst in his pitching shoulder but is expected to be ready for spring training. The team said in a statement Tuesday that Lyon had the cyst drained two weeks ago and has been throwing without discomfort since. The right-hander is expected to begin workouts with his new club Feb. 20, when pitchers and catchers report for spring training in Kissimmee, Fla.

He might be about 10 days behind in his throwing program, the Astros said. Houston signed Lyon as a free agent in December to a $15 million, three-year contract.
