Johan Santana underwent knee surgery today:

Wow. I just received a call from the Mets, who said Johan Santana had successful surgery to repair a torn meniscus in his left knee. The procedure was arthroscopic, and was performed today by team physician Dr. Stuart Coleman at the Hospital for Special Surgery in Manhattan.

The release said Santana suffered the torn meniscus before his last start -- Saturday's three-hitter on three-days rest that saved the Mets' season for another day. I've posted the complete release below. Let the legend grow...

That's the definition of a gamer.
