Rafael Nadal saved a match point and rallied from two service breaks down in the third set to edge Russia's Daniil Medvedev 6-7 (3-7), 6-3, 7-6 (7-4) on Wednesday and record his first victory at this year's ATP Finals.

The world No. 1 is known for his indomitable fighting spirit, but even he looked deflated in this round-robin contest when he went down 5-1 in the deciding set against an opponent who had all the answers in their lengthy baseline rallies.
