The 2012 US Open is almost at its halfway stage and top seeds Andy Murray, Roger Federer and Serena Williams will be in action on Day Six of the final Grand Slam title of the year.
The highlight of the fifth day was Great Britain's Laura Robson and her second upset in as many matches at Flushing Meadows. The 18-year-old beat former World No 1 and three-time US Open champion Kim Clijsters in the second round and followed that with a 6-4, 6-7, 6-2 win over ninth seed Li Na of China. Her reward is to face defending champion and seventh seed Samantha Stosur of Australia for a place in the quarter final. Robson, who has been on a high since winning silver at the London Olympics 2012, is the first British woman to reach the fourth round of a Grand Slam tournament in 14 years.
