Nishikori savors revenge against 2012 champion

Andy Murray lost his way, seven consecutive games and, eventually, his riveting five-set US Open quarterfinal against Kei Nishikori after a loud noise from a malfunctioning sound system interrupted a key point, resulting in a do-over.

Whether or not the gong-like sound, and chair umpire Marija Cicak's let ruling, was the reason that Nishikori wound up coming back to win 1-6, 6-4, 4-6, 6-1, 7-5 on Wednesday, it surely will be what's most remembered about the back-and-forth, 4-hour match.
