Last year Mariano Rivera changed his mind about retiring after knee surgery ended his season, but Buster Olney of ESPN.com writes that “it’s an open secret” the Yankees closer “intends to retire” following this season.

In fact, according to Olney “that announcement figures to be very soon, perhaps Saturday.”

Obviously the motivation to return from a significant injury played a part in Rivera deciding to play another season, but he’s 43 years old and has been pondering retirement since at least this time last year. On the other hand, it’s worth noting that when players announce an entire season ahead of time that they plan to retire there are lots of examples of minds later being changed.
