Roger Federer did not play his best tennis against Verdasco on Wednesday, but it was still enough to reach the Dubai Duty Free Tennis Championship quarter-finals. The Swiss player prevailed in three sets, 6-3 3-6 6-3, to record his 50th win in the Arab tournament. Federer is seeking his eighth title in the event, he will face Marton Fucsovics next. At last year's Australian Open Federer defeated Fucsovics after that both of them played a good match. The 37-year-old opened his campaign here defeating the German Phikipp Kohlschreiber in three sets.
