Sammy Gervacio had surgery last week on his throwing shoulder.

The Astros haven't revealed an exact timetable for his recovery, but it's probably going to take at least two or three months. He will have to begin the year at Triple-A and will only be brought back up if his results there are good. The 25-year-old right only made six big league appearances in 2010 but he had a strong 3.48 ERA and 1.07 WHIP in the minors.

Astros re-signed RHP Sammy Gervacio to a minor league contract.

He'll receive an invite to major league spring training. Gervacio, 25, was non-tendered by the Astros earlier this month after making just six appearances this past season due to shoulder problems.

Astros GM Ed Wade said his team would like to bring back Sammy Gervacio but that they couldn't risk him being stuck on the major league disabled list.

Gervacio was shut down in early May with shoulder issues, and MLB rules state that if he continued to be affected by the injury in spring training and didn't make the team, he would have to be placed on the major league DL and thus earn a major league contract. If Gervacio signs a split minor league contract, he can be kept on the minor league DL, saving the Astros money.

Gervacio has twice had to leave outings with the Astros this season with a shoulder injury, and although cortisone injections have helped a bit, he is still dealing with soreness.
