Must Susana get Tommy John surgery? I rooted for the Mets and then the Yankees in the 1970s, but don't remember Tom Seaver or Ron Guidry needing TJS. Is it a current problem, or is this just expecting the worst so anything less than worst is good? Of the current big three minor league pitchers, neither Cavalli, nor Henry, nor Rutledge have had TJS, at least as best I can remember.
Overall, the Nats have been careful with the arms of their young pitchers, so maybe the organization will take equal care of Susana. He only pitched three innings on Wednesday...
