Novak Djokovic easily beat 13th-seeded Jo-Wilfried Tsonga 6-1, 6-4, 6-1 in only 1½ hours Sunday at the French Open to reach the quarterfinals for the 20th major tournament in a row.

The second-seeded Djokovic needs a title at Roland Garros to complete a career Grand Slam. He lost the 2012 final and in last year's semifinals — both times to Rafael Nadal.

Djokovic improved to 12-5 against Tsonga, including winning their last 10 matches and the past 15 sets they've played.

In the quarterfinals, Djokovic will face No. 8 Milos Raonic of Canada, who beat Marcel Granollers of Spain 6-3, 6-3, 6-3.
