Nadal held his service game, and had Nishikori on the ropes on his serve, but Nishikori escaped with some good serving. Nishikori might be running out of steam, but he still is up a break at 3-1. Nadal has to hold and try to keep pressure on Nishikori. Crowd screaming for Nadal on Nishikori errors and during points. Nishikori complained to chair ump, but chair ump said he can do nothing. Didn't even make an announcement to ask the crowd to stay quiet during points. Not that it would help...this is Madrid
Respectfully,
