They traded breaks in the first two games, then held serves rather comfortably going to the tiebreak. Tursunov's far better 2nd serve win % was the decisive factor there.
In the second set Tursunov seemed to forget how to hit fist serve whereas Mahut improved drastically in this department. Mitya still has an excellent chance to get the break back but failed to capitalize on Mahut's shaky serving in the last game.
The third set was somewhat illogical as Tursunov struggled in virtually each of his service games and Mahut was holding easily despite barely putting 1st serve in. Then, all of sudden, Tursunov breaks at 3-2 and cruises to a victory.
