Brandon Lyon underwent minor surgery two weeks ago:

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.

Better now than in the middle of the season.
