US Open 2014, against Gael Monfils
Federer has been two sets down to love – but here, he was also two match points down. After a quick loss in the first two sets – 4-6, 3-6 to Monfils, it seemed the Frenchman was tiring significantly, and Federer quickly took advantage to win the third set 6-4.
Although the next game was far closer, it was Monfils who had the upper hand here – holding two match points in that set. Unfortunately for the Frenchman, however, he crucially gifted Federer not one but two double faults in the set – bringing Federer right back into control.
Dialing up the attack, Federer went on to win the next 5 games on the trot, taking the final set 6-2 and with it, the match.
