It was announced yesterday that he's coming out of retirement!

Who am I talking about?..... MICHAEL PHELPS !
He's competing in an event in Arizona later this month. It'll be his first race since he retired after the London Games in 2012 . . . although he's been training since last fall.
He hasn't explicitly said that he's gearing up for the 2016 Summer Olympics in Brazil.
His longtime coach  says, quote, "I think he's just going to test the waters a little bit
and see how it goes. I wouldn't say it's a full-fledged comeback."
Phelps hasn't directly commented. But a while back, he vowed that he wouldn't swim into his 30s . . . and he'll turn 29 in June.
