Wozniacki hits top form to ease way into quarter-finals
A resurgent Caroline Wozniacki surged into the quarter-finals of the US Open yesterday, beating eighth seeded American Madison Keys 6-3, 6-4.
Progress to the next round already makes this Grand Slam competition the most successful major tournament for the Dane in two years.
Wozniacki, a US Open finalist in 2009 and 2014 but unseeded this year after being sidelined for two months by an ankle injury, dominated from the start and wrapped up victory in a speedy 78 minutes on a sun-splashed Arthur Ashe Stadium court.
After rallying from a set and a break down in her opening match and then coming back from 5-1 down in the third to beat Japan's Naomi Osaka, Keys could not find a way round the former world No 1, who took no chances, closing out the match on her first match point.
Next up for the 74th-ranked Dane is Anastasija Sevastova, who shocked Britain's No 1 Johanna Konta 6-4, 7-5.
The result made Sevastova the first Latvian woman to reach the quarter-finals since 1994.
The unseeded 26-year-old, who defeated third seed Garbine Muguruza in round two, held off a late fightback from Konta to reach the last eight of a grand slam for the first time.
Sevastova was out of the game for 20 months until the start of last year, having announced her retirement in May 2013 after a series of injuries.
Both Williams sisters advanced to the fourth round with straightforward victories.
In the men's tournament, Gael Monfils motored into the quarter-finals with a straight-sets dismissal of Marcos Baghdatis.
Monfils, who has enjoyed a run of success this hard court season, maintained his impressive form with a 6-3, 6-2, 6-3 romp.
