LONDON - Danish fifth seed Caroline Wozniacki was sent packing from Wimbledon on Monday, succumbing 7-6(4) 6-4 to the relentless big-hitting of American Coco Vandeweghe.
The last-16 match pitted Vandeweghe's power against Wozniacki's consistency. The American, ranked 25, was more aggressive and took more risks, and her strategy paid off - she fired 38 winners across the net compared with her opponent's 16.
There was little between the players in the first set, which Vandeweghe edged in the tiebreak, cheered on by her Australian coach Pat Cash, a former Wimbledon champion.
She closed out the match with a break at the end of the second set, forcing an error from the 26-year-old Wozniacki with a ferocious cross-court forehand.
By reaching the quarter-finals, the 25-year-old Vandeweghe has matched her best performance at the All England Club. She will face Slovakia's Magdalena Rybarikova, ranked 87.
Meanwhile, second seeded Simona Halep ended Victoria Azarenka's hopes of becoming the first mother in 37 years to win Wimbledon with a 7-6 (7/3), 6-2 fourth round victory on Monday.
Halep, who will become the new world number one if she makes the semi-finals, next faces Britain's sixth seed Johanna Konta.
Sixth seed Konta became the first British woman for 33 years to make the Wimbledon quarter-finals on with a 7-6 (7/3), 4-6, 6-4 win over France's Caroline Garcia.
Konta will face either former world number one Victoria Azarenka or second seeded Simona Halep for a place in the semi-finals.
In action from the men's draw, Croatian seventh seed Marin Cilic reached a fourth successive Wimbledon quarter-final with a 6-2, 6-2, 6-2 win over Roberta Bautista Agut of Spain.
Cilic, the 2014 US Open champion, will look to reach his first semi-final at the All England Club when he faces either two-time champion Rafael Nadal or Gilles Muller of Luxembourg in the last-eight.
