Paris, France (Sports Network) - World No. 1 Novak Djokovic and seven-time champion Rafael Nadal each moved into the fourth round at the French Open.
The Australian Open titlist Djokovic capped Saturday's festivities on Court Chatrier by dismantling promising 26th-seeded Bulgarian Grigor Dimitrov 6-2, 6-2, 6-3 in 1 hour, 44 minutes.
Dimitrov upset Djokovic an ATP Masters event in Madrid last month.
Djokovic reached his first-ever French Open final last year, only to lose to his great rival Nadal in four sets.
The third-seeded former No. 1 Nadal got past 27th-seeded flashy Italian shot- maker Fabio Fognini 7-6 (7-5), 6-4, 6-4, also on Chatrier.
Nadal, who will turn 27 on Monday and is seeking a fourth straight title at this clay-court Grand Slam event, is now 55-1 lifetime at Roland Garros.
His fourth-round opponent will be 13th-seeded rising Japanese Kei Nishikori, who topped 24th-seeded Frenchman Benoit Paire 6-3, 6-7 (3-7), 6-4, 6-1 on a sunny, breezy Day 7. Nishikori is the first Japanese man to reach the fourth round at the French since 1938.
In the match of the tournament thus far, 12th-seeded 35-year-old resurgent German Tommy Haas outlasted 19th-seeded American marathon man John Isner 7-5, 7-6 (7-4), 4-6, 6-7 (10-12), 10-8 in 4 hours, 37 minutes. Isner saved 12 match points in a dramatic fourth set, as the towering American battled Haas for 46 points over 31 minutes at one point to survive the stanza.
Haas saved a match point against in the fifth and ultimately converted on his 13th match point to stave off Isner, who fired 27 aces in a gut-wrenching setback.
The 6-foot-9 Isner holds the record for the longest-ever tennis match, when he beat France's Nicolas Mahut in 11 hours, 5 minutes over three days at Wimbledon three years ago.
The one-time world No. 2 Haas will face Russian veteran Mikhail Youzhny in the round of 16.
Meanwhile, seventh-seeded crowd favorite Richard Gasquet blew past former world No. 3 Russian Nikolay Davydenko 6-4, 6-4, 6-3, the 29th-seeded Youzhny upended eighth-seeded Serb Janko Tipsarevic 6-4, 6-4, 6-3, and ninth-seeded Swiss slugger Stan Wawrinka bested 21st-seeded 6-foot-8 Pole Jerzy Janowicz 6-3, 6-7 (2-7), 6-3, 6-3. Gasquet and Wawrinka will lock horns in round four.
