Nadal, Djokovic into quarterfinals

Nine-time champion Rafael Nadal and title-holder Novak Djokovic surged into the French Open quarter-finals for a record-equalling 11th time yesterday, but reigning women's champion Garbine Muguruza crashed out in the last 16.

Nadal continued his ruthless form at Roland Garros by dispatching Spanish 17th seed Roberto Bautista Agut 6-1, 6-2, 6-2 to match Roger Federer's mark of last-eight appearances in Paris.

The 14-time major winner has dropped just 20 games in four matches as he strives to become the first man to win 10 titles at a single Grand Slam.

The fourth seed will meet compatriot Pablo Carreno Busta, through to his first Slam quarter-final, for spot in the last four after the latter stunned Canada's Milos Raonic.

Djokovic also became an 11-time quarter-finalist as he sauntered past Spain's Albert Ramos-Vinolas 7-6 (7/5), 6-1, 6-3.

The Serb needed 75 minutes to clinch the opening set but then outclassed the 19th seed to set up a showdown with Dominic Thiem.

Austrian sixth seed Thiem thrashed Argentina's Horacio Zeballos 6-1, 6-3, 6-1 to reach the quarters for a second straight year.

Japan's Kei Nishikori, who faces Fernando Verdasco next, fought off a fierce challenge from South Korea's Hyeon Chung in an all-Asian tussle held over from Saturday following rain to clinch a place in the last 16.

Chung quickly forced the contest into a fifth set as play resumed on Sunday, but the world number 67 double faulted on match point to gift Nishikori a 7-5, 6-4, 6-7 (4/7), 0-6, 6-4 victory.

Karen Khachanov will play Andy Murray in the fourth round after the giant Russian beat American 21st seed John Isner 7-6 (7/1), 6-3, 6-7 (5/7), 7-6 (7/3).

Kristina Mladenovic ensured the host nation will have two women in the quarter-finals for the first time since 1994 after dumping out fourth seed Muguruza 6-1, 3-6, 6-3.

The French 13th seed is through to just her second Slam quarter-final -- after the 2015 US Open -- and will face Switzerland's Timea Bacsinszky for a spot in the last four.

The Swiss 30th seed, a 2015 semi-finalist, defeated 2002 runner-up Venus Williams 5-7, 6-2, 6-1 to guarantee a first-time major champion will be crowned next Saturday.
