The defending champion Roger Federer has crushed long time rival Rafa Nadal in straight sets, 6-3, 6-0, at the ATP World Tour Finals in London to confirm his place in the final four.
It was the 26th time the pair had played one another, although Nadal still has a healthy overall lead despite the result having won 17 matches to Federer's nine.
Nadal the world number two must now beat Frenchman Jo-Wilfried Tsonga on Friday in his final group match to remain in contention for the title he's never won.
