On The Meaning of Tommy John Surgery

Will Carroll, who probably knows more about baseball injuries than anyone on the planet who hasn’t been to a good medical school, is back with another look at Tommy John surgery and there’s stuff in there I didn’t know.

↵From Carroll’s big finish:

↵↵This operation has leapt from a long shot, something in the imagination of a doctor who loved baseball, and has become something that may have saved or at least changed the game. In ‘09, one out of every nine pitchers in a major league rotation had that triangular scar on the back of their pitching elbow ... It’s not that pitchers are coming back better, stronger, or faster; it’s that they’re coming back the same, keeping talent in the game.

↵↵You’ll want to read the whole thing. This stuff is worth knowing.
