Masterson has undergone successful arthroscopic surgery on his right shoulder, Jon Heyman of CBS Sports reports.

EDGE Analysis

Masterson is expected to be as close to full health as he's been in two years by the time spring training arrives. A free agent after his release from Boston, the right-hander will look to catch on with a new club. His first opportunity offered will likely be a low-risk deal, such as a minor league contract or non-roster invite to camp.
