Novak Djokovic advanced Wednesday to the semifinals of the only Grand Slam tournament he has yet to win, beating Tommy Haas 6-3, 7-6 (5), 7-5 at the French Open.
The No. 1-ranked Djokovic's opponent Friday will be seven-time champion Rafael Nadal, who hammered Stanislas Wawrinka 6-2, 6-3, 6-1.
Djokovic, the winner of six major titles, seeks to become the eighth man to complete a career Grand Slam.
He eased past the 35-year-old Haas, winning 40 of his first 43 service points. Haas found himself on the verge of pulling even at 5-all in the tiebreaker, but Djokovic smacked a backhand winner to end a 24-stroke rally and won the next point as well for a two-set lead.
Djokovic reached his 12th consecutive Grand Slam semifinal.
