Nadal bows out on top of the world
Rafael Nadal was unable to crown his season with a first ATP Finals title but he ends it as world number one and with a chance to lead Spain to Davis Cup glory.
The Spaniard, who came to London under an injury cloud, had a terrible start to his week at the O2 Arena, crushed in straight sets by defending champion Alexander Zverev in his first round-robin match.
But he produced a performance of astonishing grit to recover from 5-1 and match point down against Daniil Medvedev and saw off Stefanos Tsitsipas in three sets on Friday.
It was not quite enough to reach the semi-finals but Nadal leaves London after securing the year-end number one ranking for a fifth time, pulling level with Roger Federer and Novak Djokovic.
Nadal was in the strange position after his win against 21-year-old Tsitsipas of not knowing whether he would be heading home or playing Federer in the knockouts.
Later, Zverev's win against Medvedev confirmed his tournament was over.
The 33-year-old, who was presented with the trophy for securing the number spot on court, said it was difficult to compare the achievement with winning a Grand Slam.
