Identical twins Mike and Bob Bryan, the most successful doubles team of all time, have announced they will retire at the 2020 US Open.

The 41-year-old Americans have won a record 16 Grand Slam men's doubles titles, 118 career titles and an Olympic gold medal together and have spent more weeks at the top of the world rankings - 438 in total - than any other pair in history.

"We took the last few months off to try and get our minds right and get our bodies and minds fresh and make this decision," Mike told USOpen.org.

"We feel it's the right time. It's just a perfect time to go. We feel like we can still be competitive and win, but we're really appreciative of getting so much longevity out of our careers.

"We feel like you can't play forever, so we just wanted to make the decision and go into next year knowing that we can see the finish line and play as hard as we can, but also appreciate being on tour, playing together and giving back to the fans a little bit."

USTA president Patrick Galbraith said: "Having known Mike and Bob Bryan for some 25 years, I know very well how much they've meant to tennis - and how much tennis has meant to them.

"They've represented our sport and our country on the world stage with unparalleled character and class; their remarkable talents matched only by their unbridled energy and enthusiasm."

The twins are now aiming to bow out with a sixth US Open men's double title in New York next August.

"We want to really play a good US Open," said Mike. "In our minds, that's where we'll hang up the sneakers.

"It's going to be amazing, playing for the fans in New York. There's nothing like it. I think we played 25 US Opens starting in '95 when we were 17 years old, just wide-eyed.

"I think we didn't weigh above 150 pounds and they wouldn't even give us our badges. They thought we were ball kids.

"We actually played in our first US Open match against Patrick Galbraith, who's now the USTA president, so it's come full circle."
