The 34-year-old Williams is playing her home event for the 16th time and owns three titles there. The American took the win despite 37 unforced errors in a match riddled with a dozen breaks of serve.

Williams, who is now 7-0 against Wozniacki will next face Spanish No12 seed Carla Suarez Navarro. The other Williams sister, world No1 Serena, caught up with her elder sibling in the quarters with a 6-2, 6-3 win over Russian two-time major champion Svetlana Kuznetsova.

In the men’s competition, Kei Nishikori took just over an hour to romp to a 6-2, 6-2 victory over Serbian Viktor Troicki and secure a place in the fourth round.

Asia’s top player will next play Belgium’s David Goffin, a 6-4, 6-3 winner over Poland’s Jerzy Janowicz. Nishikori sent down five aces, 16 winners and broke Troicki, ranked 39 in the world, on five of six break points in a truly dominant performance.

The 25-year-old, who reached his first grand slam final last year the US Open where he lost to Marin Cilic, beat David Ferrer and Roger Federer on his way to the Miami semis last year only to withdraw prior to his match with Novak Djokovic due to a groin injury
