[4] Stan Wawrinka (SUI) vs [5] Kei Nishikori (JPN)

This is a 50-50 match.  Their US Open match last year was an absolute war.  Nishikori seems poised to do what Stan did last year.  Wawrinka has momentum from Davis Cup and his title in India.  This is a fascinating match because Stan’s game at its best bullies an opponent and hits through and opponent. Nishikori wants to catch the ball early and rob an opponent of time.  So this match will be determined by how much Stan can push Kei backward.  Watch Kei’s court positioning, and you will be able to tell who is winning that segment of the match.  I am still undecided on how this match will turn out as I am typing.  Here goes: Stan Wawrinka d. Kei Nishikori 6-4, 4-6, 7-5, 7-5

[1] Novak Djokovic (SRB) vs. [8] Milos Raonic (CAN)

Milos has been quite consistent.  I think even on this surface he can hit and serve through Djokovic at times.  The problem is going to be the times that Nole is dictating play.  Novak is built for plexicushion having won 4 of the 7 Australian Opens held since the surface switched in 2008.  If Milos can return well, he can keep this match close and perhaps win.  I think Novak’s return will allow him to eventually breakthrough and take Milos down.  Novak Djokovic d. Milos Raonic 7-6, 4-6, 6-4, 6-2
