World No. 2 Rafael Nadal lost 6-1, 7-6 to Russian Nikolay Davydenko on Wednesday to become the first player to exit the ATP World Tour Finals.
After losing both of his Group B clashes in straight sets, the Spaniard has no chance of progressing any further in the elite eight-man event, even if he beats Novak Djokovic in his final round-robin match Friday.
