Bob and Mike Bryan

The Bryan Brothers are identical twin brothers Robert Charles "Bob" Bryan and Michael Carl "Mike" Bryan, American professional doubles tennis players, and are the most successful duo of all time. They were born on April 29, 1978, with Mike being the elder by two minutes. The Bryans have won multiple Olympic medals, including the gold in 2012 and have won more professional games, matches, tournaments and Grand Slams than any other men's pairing. They have held the World No. 1 doubles ranking jointly for 438 weeks (as of October 25, 2015), which is longer than anyone else in doubles history, and have also enjoyed that world number one ranking together for a record 139 consecutive weeks. They have also finished as the ATP year-end number 1 doubles team a record 10 times. Between 2005 and 2006, they set an Open Era record by competing in seven consecutive men's doubles Grand Slam finals.

They are also well known for celebrating winning points by chest-bumping each other. Some of their success is attributed to their particular brand of twinship: the Bryans are "mirror twins", where one is right-handed (Mike) and the other left-handed (Bob). This is advantageous for their court coverage. They were coached by David Macpherson between 2005 and 2016. In January of 2017 they reunited with Coach Phil Farmer, who previously coached them to their first grand slam title, French Open men's doubles.

On October 28, 2016, they recorded their all-time record 1000th match win, as a team, by defeating Pablo Cuevas and Viktor Troicki in the quarter finals of the 2016 Erste Bank Open, in Vienna, Austria. Following their triumph at the 2013 Wimbledon Championships, the Bryans became the only doubles pairing in the Open Era to hold all four major titles at once, as well as the only team in history to earn all four majors and Olympic gold during a one year period of time. They are also the only doubles team in history to have won every major title, having won all four Grand Slams, Olympic Gold, every (all 12 versions of the 9 tournaments) ATP World Tour Masters 1000 title, the ATP World Tour Finals and the Davis Cup during their careers.
