Nadal unraveling. Broken again. Down love - 30 immediately, then Nishikori kindly gave up two unforced errors, then Nadal double faulted to hand Nishikori a break point. Nadal failed to get the first serve in, and looped a slow second serve which Nishikori quickly crushed to Nadal's forehand side, and Nadal couldn't handle it. This set is probably gone unless Kei muffs it. Nadal looks discouraged, not surprisingly. Let's see if he can fight back.
Respectfully,
