Mariano Rivera said he wasn't finished. He now has a timeline in sight. Rivera told reporters Wednesday that he will have surgery on the torn ACL in his right knee June 12, and that he expects to be ready to pitch again by the start of next season. "Oh yeah, there's no doubt about that, God willing," Rivera said. The surgery will be performed by Dr. David Altchek in New York, and was pushed back a few weeks after a blood clot was discovered in his right knee. Rivera was told last week that the blood clot was gone, though he will have to remain on blood-thinning medication for an unspecified time following the surgery. Rivera is done thinking about a 2012 return after injuring his knee while shagging fly balls. "I can't. I don't wanna think about it. ... I just have to be able to do what I was doing before. That's what I want," Rivera said. "I always believe in miracles. You have to get it fixed first."
