Mariano Rivera hinted on Monday that the 2012 season could be his last. But unless he changes his mind and makes an official announcement before the end of the season, we'll be left to look for clues that could indicate his plans. (Jack Curry, for instance, tweets today that Rivera was throwing batting practice to his son, explaining that he can't recall him doing that in Tampa previously. Get used to things like that.) In any case, there's at least one person outside of Rivera's family who knows what the closer plans to do: Derek Jeter. But he says he's not telling, either.

From the Record:

“I talked to Mo. Let’s do it this way. You’re not going to get anything from me about Mo,’’ Jeter said. “Mo told you what he wanted to tell you. He’ll share his thoughts and opinions with you when he’s ready.

In the meantime, we remain fascinated by the idea of Rivera getting a chance to play in center field at some point this season (if it is indeed his last), and Joe Girardi was asked about it again yesterday. From the LoHud Yankees Blog:

Girardi is, of course, a little worried about his closer being hurt while patrolling the outfield in the ninth inning of a meaningless game, but someone brought up the fact that the bullpen is just a short jog from center field.

Rivera could take matters into his own hands.

“What if he was to run out there and say (to Curtis Granderson), ‘You’re out,’” Girardi said. “What are you going to say to him?”

Not that it would ever actually play out like that, but Rivera might be so well-liked that he could pull something like that and get away with it.
