In the final set, Nadal broke Baghdatis in the third game, and then won on his second match point."Baghdatis is a very good player, and I am happy that I have passed the opening test," Nadal said.Third-seeded Nikolay Davydenko of Russia also advanced, beating Younes El Aynaoui of Morocco 6-7 (2), 7-5, 7-5. ."Davydenko struggled to adapt to the outdoor hardcourt at the Aviation Club after coming from the European indoor season."It was difficult for me to return his (El Aynaoui's) serve after my tough week in Rotterdam," Davydenko said. "It's a different surface and different conditions - indoors to outdoors and quite windy. I tried to get used to it by practicing on Monday, but obviously haven't as yet.
