World No. 4 Andy Murray has been defeated by Stanislas Wawrinka in the third round of the U.S. Open. Murray was one of the top contenders at this tournament but will finish yet another year without getting his first grand slam victory of his career.
In the 6-7, 7-6, 6-3, 6-3 victory Wawrinka probably had the biggest win of his career, and the biggest upset of the 2010 U.S. Open. While Murray played tentatively, Wawrinka was able to take advantage with some great serving and heavy groundstrokes. He improved to 2-4 against Murray on hardcourts in his career.
