Rafael Nadal secured top spot in Group A at the ATP Tour World Finals with a victory over Tomas Berdych that also sent Stanislas Wawrinka into the semi-finals.
Nadal had already qualified for the last four of the season-ending event at London’s O2 Arena and his 6-4, 1-6, 6-3 win against Berdych ensured a first place finish with a 100 per cent record from his three group matches.
Czech fifth seed Berdych could have gone through with a win, but instead he was eliminated and Swiss seventh seed Wawrinka progressed to the last four following his 6-7 (3/7), 6-4, 6-1 victory over Spanish third seed David Ferrer earlier on Friday.
Nadal’s semi-final opponent on Sunday will be either old rival Roger Federer or Argentine fourth seed Juan Martin del Potro, depending on the winner of Saturday’s Group B clash between those two.
Wawrinka, playing in the Tour Finals for the first time, will take on Group B winner Novak Djokovic in the other last four clash.
“Stan came to the locker room and said good luck. I said I would try my best. It’s a good result for Stan. He’s good friend of mine,” said Nadal.
“I wish Tomas a good holiday and good luck for the Davis Cup final (against Serbia).
