DOHA, Qatar, Jan. 8 (UPI) -- Nikolay Davydenko posted his second consecutive victory over world No. 1 Roger Federer, taking a straight-set win Friday at the Qatar Open.
Federer beat Davydenko each of the first 12 times they played before the Russian got his first win over Federer in November at the Barclays ATP World Tour Finals. Friday he doubled his win total with a 6-4, 6-4 win in the Qatar Open semifinals.
Davydenko, seeded third, will meet world No. 2 Rafael Nadal in Saturday's finals. Nadal topped No. 5-seeded Serbian Viktor Troicki 6-1, 6-3 in his semifinal.
Davydenko recorded breaks the first two games Federer served to take control of the first set and used a break at 1-1 of the second for the edge there. Federer was able to solve Davydenko's serve just once in the match.
Nadal, from Spain, had little trouble against Troicki, using a steady game in which he was forced into one break-point situation. He hasn't dropped a set in his four matches in Doha and no one won more games in a set against Nadal that Troicki's three in the final set Friday.
Davydenko and Nadal have split their eight career meetings, with Davydenko topping Nadal in the round-robin section at last year's World Tour Finals in the most recent pairing.
Nadal, whose play was limited last year by injuries, is looking for his first ATP title since May and 37th of his career. Davydenko owns 19 ATP championships.
