NEW YORK (Reuters) - Marathon man Kei Nishikori secured a monumental upset by sweating out a 6-4 1-6 7-6(4) 6-3 win over world number one Novak Djokovic at the U.S. Open on Saturday to become the first Asian man to reach a grand slam final.
In a remarkable display of endurance, Nishikori followed up punishing five-set wins over third seed Stan Wawrinka and fifth seed Milos Raonic with an even more extraordinary effort, grinding down the top-ranked Djokovic in two hours, 52 minutes on a sweltering Arthur Ashe Stadium court.
