Mikhail Youzhny of Russia has beaten Stanislas Wawrinka of Switzerland in five sets to advance to the U.S. Open tennis semi-finals.
The 12th-seeded Russian trailed two sets to one before coming back to claim a 3-6 7-6 3-6 6-3 6-3 victory in a gruelling groundstroke battle on another cool, blustery day on Arthur Ashe centre court.
Wawrinka, seeded 25th, was coming off a five-set win over 20th-seeded American Sam Querrey in the fourth round following a nearly four-hour long upset of British fourth seed Andy Murray and in the end could not keep pace.
Youzhny, who also reached the semi-finals at the 2006 U.S. Open, will play the winner of the quarter-final between top-seed Rafa Nadal and fellow Spaniard Fernando Verdasco.
