Andy Murray defeated Jo-Wilfried Tsonga in straight sets to set up a quarter final meeting with Novak Djokovic at the US Open.
Eighth seed Murray sealed a 7-5 7-5 6-4 victory on Monday in his first triumph over a top 10-ranked opponent in 2014 to seal his fifth consecutive quarter final place at Flushing Meadows.
Murray's last win over one of the sport's elite performers came at Wimbledon 2013, in his clash with his next opponent Djokovic.
The British number one dropped just three points in his opening service game but was still unable to fully capitalise on his lead, allowing Tsonga back into the contest. The Frenchman managed to keep within touching distance of his opponent until Murray earned a second break point with a terrific backhand before sealing the opening set.
In near identical circumstances, Murray's service game in the second set was just as emphatic as he sealed another 7-5 win, again keeping Tsonga at arm's length.
Murray fell behind at the start of the third set but Tsonga failed to help his cause with a string of errors. A woefully misdirected backhand allowed the Scot to regain the advantage in the fourth game before he suffered two double faults in his service game, handing the initiative to Murray to seal the victory after three match points.
"Today was a good match for the most part," Murray said after the victory, BBC Sport report.
"I feel like I'm playing well. I'm going to have to play extremely well to win the event or even just to get through the next match.
"You never know what can happen in a couple of days. A week ago I didn't feel great at all.
"Obviously after the first match [when he struggled physically] was a big concern, and now a week later I'm in the quarters. A lot can happen in a few days."
