Serena, Venus lead US Tennis into Rio Olympics

World number one Serena Williams, her sister Venus and the Bryan brothers head up the list of names competing for US Tennis at the Rio Olympics this summer.

Serena Williams was included in the team that was announced on Friday and the double Olympic champion in 2012 will be looking to defend her titles from the London games, where she triumphed in both the singles and doubles.

Serena, who only recently won her 22nd Grand Slam title at Wimbledon, will team up with Venus for the doubles again after picking up gold medals in 2000, 2008 and 2012

Bethanie Mattek-Sands and CoCo Vandeweghe are the other women's doubles pairing, while Venus joins Madison Keys and Sloane Stephens as the US women's singles hopes.

Bob and Mike Bryan have spent 435 weeks in total at the summit of the world doubles rankings and they provide the US team with their other best hope of gold in Rio, with Steve Johnson and Jack Sock making up the second doubles partnership.

Denis Kudla and Brian Baker complete the rest of the US men's side, with Sock and Johnson both joining them in the singles.

US number one John Isner misses out on the squad having revealed earlier this year he would not compete in Rio.
