LONDON, July 5 (Xinhua) -- Seven-time champion Novak Djokovic joined men's top seed Jannik Sinner to reach the fourth round at Wimbledon with a straight-sets win over Miomir Kecmanovic on Saturday.

Chasing a record 25th Grand Slam singles title, Djokovic dominated the all-Serbian clash 6-3, 6-0, 6-4 to secure his 100th Wimbledon win - a milestone previously reached only by Martina Navratilova and Roger Federer.

"It's very historic, it sounds very nice. I'm very grateful and privileged to be in this position," Djokovic said during his on-court interview. He will next face Australia's Alex de Minaur, who defeated August Holmgren of Denmark in straight sets.

World No. 1 Sinner continued his flawless run, dispatching Spain's Pedro Martinez 6-1, 6-3, 6-1 in just one hour and 55 minutes.

The Italian, yet to drop a set in the tournament, will meet 19th seed Grigor Dimitrov, who also cruised past Sebastian Ofner in straight sets.

Tenth seed Ben Shelton of the United States maintained his perfect set record in this year's event, overpowering Marton Fucsovics of Hungary 6-3, 7-6 (4), 6-2 to set up a clash with Italy's Lorenzo Sonego.

2014 US Open champion Marin Cilic of Croatia overcame Spaniard Jaume Munar 6-3, 3-6, 6-2, 6-4, booking a showdown with Italy's Flavio Cobolli for a quarterfinal berth.

Women's eighth seed Iga Swiatek of Poland avenged her Rome loss to American Danielle Collins with a dominant 6-2, 6-3 win. She next faces Denmark's Clara Tauson, who stunned 11th seed Elena Rybakina 7-6 (6), 6-3.

Czech player Barbora Krejcikova saw her title defense end after a 2-6, 6-3, 6-4 defeat to Emma Navarro of the United States.

Navarro will play 18-year-old Mirra Andreeva, who eased past Hailey Baptiste 6-1, 6-3.
