Rafael Nadal put together one of the more impressive performances of his career during the ATP Finals. On Wednesday, he rallied from down 5-1 in the third set against Daniil Medvedev to win 6-7 (3-7), 6-3, 7-6 (7-4), in London.

In the first set, Medvedev won four consecutive games and was able to take advantage of Nadal's miscues. However, Nadal rebounded in a big way and won the opening game of the second set. Nadal won the second set 6-3 and was able to force a third and deciding set.

Nadal didn't exactly have the most success out of the gate in the third set as he dropped the first four games and ultimately dug himself into a 5-1 hole. However, Nadal was able to battle his way back and force a tiebreak in which he came away with a 7-6 victory.

Nadal is having a very strong year, winning at both the French and U.S. Open, where he and Medvedev played in one of the greatest U.S. Open finals of all-time.
