Nishikori upsets Murray to reach U.S. Open semi-finals

By Larry Fine

NEW YORK ( Reuters) - Japan's Kei Nishikori overcame second seed Andy Murray for a grueling 1-6 6-4 4-6 6-1 7-5 victory on Wednesday to reach the U.S. Open semi-finals.

Nishikori, who became the first Asian man to reach a grand slam final when he finished runner-up at the 2014 U.S. Open, broke the Scotsman in the 11th game of the fifth set with a brilliant reflex volley and served out to complete the comeback triumph.

The upset ended a stellar run by Murray that had taken him to seven successive finals, including victories at Wimbledon, the Rio Olympics, Queen's Club and Rome.

The sixth-seeded Nishikori will meet either double grand slam winner Stan Wawrinka or 2009 U.S. Open champion Juan Martin del Potro in the last four at Flushing Meadows.
