Stan Wawrinka (22) is one of two players that Federer played over 20 times during the 2010s decade.

The more illustrious Swiss continued his dominating run against his good friend and compatriot, winning 20 of 22 games. Federer's only losses against Wawrinka came in the 2014 Monte Carlo Masters final and the 2015 Roland Garros quarterfinals.

Federer saved multiple match points in a rare ill-tempered match against his compatriot in the semifinals of the 2014 ATP Finals, which is the closest Wawrinka has come to beating Federer outside of clay. In the pair's last meeting, Federer beat Wawrinka in four sets in the 2019 Roland Garros quarterfinals.

The defeats include missed match points in the 2010-11 US Open semifinals and in the 2019 Wimbledon final, where Djokovic became the first Wimbledon champion in 71 years after saving multiple championship matches.
