First Pitch: What will Mo decide?

If Mariano Rivera were to retire, he would finish with 608 saves, the most in the history of the game. He would leave with 42 more in the postseason. He would have been a part of five World Series titles.

He would be the greatest closer of all time.

Rivera, 42, has nothing left to accomplish as a baseball player. He has his honor, his records and his rings.

Before this season, Rivera hinted that this would be his final year, but he never came right out and said it, leaving everyone to imagine what he meant. Most felt this would be the end. He said he was "1,000 percent sure" of his decision.

Now, after tearing his ACL, what happens to the the "1,000 percent"? Does Rivera walk away this way? Or does the man who always wanted to leave on top go through a long, arduous knee rehabilitation so he can play one, maybe two more years?

An emotional Rivera was understandably not ready to make any proclamations or promises after he found out he had torn his ACL.

"All that depends on how the rehab is going to happen," Rivera said. "From there, we'll see."

Rivera can leave as one of the classiest and respected players of all time. When he does call it a day, he will, fittingly, be the final player to regularly wear No. 42, which has been retired to honor Jackie Robinson.

But does Rivera want to go out like this? There is no shame in it, of course. His legacy, both on the field and off, is intact. Still, does the man who wanted to go out when he said so limp away from the game, or does he add another chapter to his legacy?
