FINAL FOUR

Nikolay Davydenko grabbed the last semifinal spot at the ATP World Tour Finals by beating Robin Soderling 7-6 (4), 4-6, 6-3 Friday, knocking defending champion Novak Djokovic out of the tournament.

Davydenko, Djokovic and Soderling all finished with two wins in the round-robin phase, but the third-ranked Serb was eliminated on sets. Soderling had already secured advancement and finished at the top of Group B.

Djokovic beat Rafael Nadal 7-6 (5), 6-3 earlier Friday, handing the Spaniard his third straight loss at the tournament.

Davydenko will face top-ranked Roger Federer in Saturday's first semifinal match. Soderling will take on US Open champion Juan Martin del Potro later in the day.
