Federer and Djokovic first played each other in a Grand Slam final at the 2007 US Open where No. 1 Federer emerged victorious in straight sets. Federer ended Djokovic's 28 straight wins in China at the 2014 Shanghai Open, and he also ended Djokovic's perfect 41–0 start to the 2011 season in the semifinals of the French Open, but Djokovic avenged this loss at the 2011 US Open in five sets after saving two match points against Federer for the second straight year. In the semifinals of the 2012 Wimbledon, Federer beat defending champion and No. 1 Djokovic in four sets. The two played three Wimbledon finals in 2014, 2015, and 2019, with Djokovic emerging victorious in all of them and even saving two match points in the latter final, which lasted almost 5 hours. The pair also met in the final of the 2015 US Open and once more Djokovic prevailed in four sets. Some experts have included the rivalry between Federer and Djokovic as one of the best rivalries in the Open Era.
