Remember earlier this spring, when Mariano Rivera said he knew what the future held, but wasn’t revealing it? Those sure sounded like the words of a man who planned to retire after the season. But according to Reggie Jackson, that might not have been the case. He told Bob Nightengale of USA Today that Mariano was actually planning to pitch in 2013, reserving his decision only so he could ensure he remained at the top of his game. That is, the greatest of all time might have a few more rounds left in him, injury or not. Obviously he has a few obstacles to clear first — “We have to face this first,” he said last night — but we could see Rivera take the mound in the ninth inning a few more times before he decides to hang ’em up.
