Bryan twins could retire after 2016 Olympics

Olympic doubles champions Bob and Mike Bryan of the United States tell Reuters that they are planning on contesting the 2016 Olympics in Rio de Janeiro, but might retire after that.

"I mean we talked about it, 2016 is a goal," Mike Bryan said. "We want to go to Rio. I mean, we're going to be 38-years-old, we're not the young guys any more, but the training starts today. We're going to get ready for it."

Bob added: "Doubles is a sport you can play until your late 30s, early 40s. A couple of guys, a lot of guys, who are Top 10 in the world in the doubles are closing in on 40. So that's our goal, we've already talked about it, and Rio, we've already put the pin on the calendar, and that's going to be a good way to shut it down."
