Nikolay Davydenko sealed the last semi-final berth at the ATP World Tour Finals on Friday, claiming the victory he needed over Robin Soderling to send 2008 champion Novak Djokovic spinning out of the tournament.

Serbian Djokovic completed Rafael Nadal’s miserable week with a 7-6, 6-3 defeat of the Spaniard but it proved in vain for the world number three, who could only sit and stew as Davydenko completed Group B by defeating Soderling 7-6, 4-6, 6-3.

With Nadal bottom of the group having lost all his matches without winning a set, the other three ended with two victories each but Soderling progressed in first place and avoided a semi-final showdown with world number one Roger Federer
