HOUSTON (AP) — 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.
"Brandon was experiencing some weakness and discomfort in his shoulder, and we brought him in a couple of weeks ago to be seen," general manager Ed Wade said. "At the time of his pre-signing physical, his right shoulder MRI showed a very small cyst, and when the MRI was repeated recently, it showed that the cyst had enlarged and was pressing on some nerves.
"Since having it drained, Brandon reports no problems, but he will be making up for a little bit of lost time when he gets to Kissimmee."
Lyon was 6-5 with a 2.86 ERA and three saves in 65 relief appearances for Detroit last year.
In other news, minor league second baseman Jose Vallejo will undergo right hand surgery Wednesday and miss most of the 2010 season.
The 23-year-old Vallejo cut tendons in two fingers while preparing a meal at his home in the Dominican Republic during the Christmas holidays. His hand slid over the blade of a knife that he was using to cut meat, the team said.
Houston acquired Vallejo last August from Texas as part of the Ivan Rodriguez trade.
