Since tennis' return to the Summer Olympic Games at Seoul 1988, four former World No. 1s — Andre Agassi (1996), Yevgeny Kafelnikov (2000), Rafael Nadal (2008) and Andy Murray (2012, 2016) — have captured the singles gold medal. In 2016, Nadal added the doubles gold medal to his collection alongside Marc Lopez. Boris Becker and Michael Stich (1992), Roger Federer and Stan Wawrinka (2008) and Bob Bryan and Mike Bryan (2012) have also clinched doubles gold for their nations.
