An ailing Andy Murray suffered a shock exit from the U.S. Tennis Open losing 6-7 7-6 6-3 6-3 to Swiss 25th seed Stanislas Wawrinka in the third round this morning.
The fourth-seeded Scot served for a two sets to love lead but suffered a left thigh problem and Wawrinka, who also had treatment for a thigh injury, recovered to take the third and fourth sets with relative ease to reach the last 16.
