World no 3 Andy Murray was given a rude shock on Monday, 7 September, when South African Kevin Anderson produced one of his best career performances to knock the Scot out of US Open.
The big-serving Anderson smashed 15 aces and 81 winners to claim a thrilling 7-6 (5), 6-3, 6-7 (2), 7-6 (0) win over Murray in a contest that lasted four hours and 18 minutes at Flushing Meadows.
Reflecting on his victory, Anderson said that he just managed to keep his composure throughout, adding that he probably played one of the best matches of his life.
Murray, the 2012 US Open winner, was punished for his complacency, after he failed to convert eight of the 11 break points that came his way.
In another match, Richard Gasquet comfortably overcame 6th seed Tomas Berdych in four sets, 2-6, 6-3, 6-4, 6-1 to secure a spot in the quarter-finals, where he will face World no 2 Roger Federer. Federer had won his 4th round match against John Isner in straight sets, 7-6 (0), 7-6 (6), 7-5.
Stanislas Wawrinka, meanwhile, defeated American Donald Young 6-4, 1-6, 6-3, 6-4 to set up a quarter-final clash with Kevin Anderson.
In women's singles, there were no surprises on Day 8, as Petra Kvitova and Simona Halep won their 4th round matches to advance to the quarters. Kvitova defeated Britain's Johanna Konta 7-5, 6-3, while Halep overcame Sabine Lisicki in three sets, 6-7 (6), 7-5, 6-2.
