David Ortiz is out a month and could miss the whole season due to tendon sheath damage in his wrist. This is scary stuff. Nomar had wrist surgery back when he was good, and then he was never good again. Ken Caminiti was having his last good season before a ruptured tendon sheath ended it and basically his career.
Well, in Caminiti's case the tendon sheath had a lot of help from all of that crack and alcohol, but his swing was pretty much toast after that too.
