According to the Boston Herald, another team that was interested in Andy Marte turned away after the Braves acknowledged the player had a tear in the ulnar collateral ligament of an elbow. A Red Sox official said the team reviewed his medical file and declared him healthy.
According to Rotoworld, if Marte has a tear in his UCL, he might someday need Tommy John surgery. It's not as big of a concern for him as it would be for a pitcher, but it could leave the Red Sox without his services for a year.
Very interesting to say the least.
