The Twins have lost projected Opening Day starter Ervin Santana for 10-12 weeks after he had surgery on the third finger of his pitching hand Tuesday. That means Santana could be sidelined until May 1. Santana, an All-Star last season, had the surgery in New York City, performed by Dr. Charles Melone. The Twins said in a release that Santana "underwent a successful capsular release/debridement procedure to his right 3rd finger MCP joint." The release also read: "After ramping up his bullpens in advance of Spring Training, Ervin experienced discomfort in his right middle finger last week. This is something he had dealt with in the past and was reviewed via MRI and x-ray at the end of the season.
