Roger Federer was eliminated from the ATP World Tour Finals yesterday, losing to Nikolay Davydenko 6-2, 4-6, 7-5 in the semi-finals.

Federer, who was broken three straight times in the first set, came within two points of winning while leading 5-4 in the third set. But Davydenko held on and then broke Federer to take a 6-5 lead before serving out the win.

It was the Russian's first win over the top-ranked Federer in 13 matches.

In the late match, US Open champion Juan Martin del Potro was facing Robin Soderling for a chance to play Davydenko in today's final.
