Tsonga beats Sock off

Jo-Wilfried Tsonga beat American Jack Sock in four sets to reach the US Open quarter-finals for the second straight year.

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 Sunday.

Sock, the last man from the United States left in the draw, was trying to reach his first major quarter-final. No American man has made the last eight at the US Open since 2011.

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 2008 Australian Open runner-up, has not reached at least the semi-finals.

Tsonga could next face top-ranked Novak Djokovic, who faces 21-year-old Kyle Edmund later Sunday. Asked what kind of match he hoped for between those two, Tsonga joked, "Really, really, really long."
