Kei Nishikori vs Rafa Nadal prediction

ATP - SINGLES: Indian Wells (USA), hard Quarterfinals of Indian Wells final where Rafa Nadal and Kei Nishikori confront. Kei Nshikori although has not been playing well I think in these games is where he gets his best tennis, also against Nadal already faced the past year where he won easily 6-2, 6-4. Now Nadal although it has improved a lot to achieve its high level of before and if in quarterfinals is because the German Zverer not won the game and allowed the Spanish advance. I think nishikori not make the same mistakes as the German and when you need to settle the match will.
