5) Kei Nishikori
It's no secret that Nishikori prefers hard courts over anything other surface. Out of his 11 ATP titles, 9 have come on hard courts. This trend carries over to Grand Slams as well. Kei has breached the quarter-final barrier six times, out of which five have been on hard courts.
Three of these happen to be quarter-final showings at Melbourne Park.
At 27, Kei's not getting any younger.
And having had a prolonged taste of top level tennis, one might think that this year could finally be the year when he breaks his Grand Slam drought. Kei has had a good feel of the conditions in Australia, having made the final at Brisbane only last week, and this should stand him in good stead before the battle at Melbourne Park.
While the US Open might act as another great opportunity, there is no doubt that Kei will be giving it his all come the first Grand Slam of the year.
