Monfils, Tsonga into US Open quarters

French duo Jo-Wilfried Tsonga and Gael Monfils are through to the US Open quarterfinals following impressive victories.

Tsonga beat American Jack Sock in four sets on Sunday to reach the last eight for the second straight year, while Monfils swept aside Marcos Baghdatis 6-3 6-2 6-3.

After failing to covert one match point in the third-set tiebreaker, the ninth-seeded Tsonga dominated the fourth for the 6-3 6-3 6-7(7) 6-2 victory.

Sock, the last man from the United States left in the draw, was trying to reach his first major quarter-final.

The 26th-seeded Sock upset 2014 US Open champ Marin Cilic in the third round, never facing a break point. But on Sunday, he had just five aces and was broken six times.

The US Open is the only major at which Tsonga, the Australian Open 2008 runner-up, has not reached at least the semifinals.

Tsonga could next face top-ranked Novak Djokovic, who faces 21-year-old Kyle Edmund later on Sunday.

Monfils’ win meant he improves to 18-2 in matches he’s played since a first-round loss at Wimbledon.

That stretch includes the highest-level tournament title of his career at Washington DC.

Three days after his 30th birthday, there were still classic Monfils moments – including an attempt to tie his shoe in the middle of a point.

But he has yet to drop at set at this US Open.

The 31-year-old Baghdatis hadn’t reached a Grand Slam round of 16 since Australian Open 2009.
