With 17 different tournaments witnessing the Roger Federer vs Tomas Berdych rivalry, it is also the highest number of tournaments in which Federer has faced any opponent. Federer leads the pair's head-to-head 20-6.

The 26 meetings between the pair have materialized in Grand Slams, ATP Finals, Masters 1000, ATP 500, ATP 250, Davis Cup as well as the Olympics. Berdych is the only player to play Federer twice at the Olympics, one of 8 players to face the Swiss maestro at all 4 Grand Slam tournaments, as well as one of 8 players to beat Federer multiple times at a Major.

Berdych became the first player to beat Federer in 24 night matches on Arthur Ashe when the Czech beat the then 17-time Major winner in 4 sets at the 2012 US Open quarterfinals. However, since a 2013 Dubai semifinal defeat, Federer has emerged triumphant on all 9 occasions he has crossed swords with Berdych.
