ATP Finals: Thiem beats Rafael Nadal in high-quality match

Dominic Thiem became the first man to move into the last four of the ATP finals event in London.

The Austrian beat Rafael Nadal 7-6 (9-7) 7-6 (7-4) in a high-quality match for his second victory of the season-ending event at the o2 arena in London.

Nadal had two set points in the first-set tie-break but could not convert with Thiem eventually securing the win on his fifth match point.

Thiem’s qualification was secured when Stefanos Tsitsipas beat Andrey Rublev.

Defending champion Tsitsipas survived a match point as he won 6-1 4-6 7-6 (8-6) in Tuesday’s other match of group London 2020.

Tsitsipas will play Nadal on Thursday with the winner joining Thiem in the semi-finals, while Rublev is eliminated after two defeats from two.
