Super lucky: Rafael Nadal on stunning comeback win over Medvedev at ATP Finals

Rafael Nadal produced an incredible fightback to beat Russian Daniil Medvedev and keep his ATP Finals hopes alive on Wednesday, saving a match point at 1-5 down in the decider before winning 6-7(3) 6-3 7-6(4).

The world number one will require a victory over in-form Greek Stefanos Tsitsipas on Friday to have a chance of reaching the semi-finals. Tsitsipas, 21, is definitely there though after thrashing Alexander Zverev 6-3 6-2 in the evening match.

Nadal looked beaten as 23-year-old debutant Medvedev broke serve twice in the decider to stand on the brink of a first career victory over the Spaniard he pushed to five sets in an epic U.S. Open final in September.
