3. Nick Kyrgios (AUS)
Another unorthodox player in our countdown, Kyrgios has an attitude of his own at the court. His most famous shot is the forehand in between his legs, or is it a backhand? Considered as the funniest player on court by many of his counterparts, he is definitely one to watch out for.
The man nicknamed "Wild Thing" loves both the grass and hard courts, having a better win percentage than his career average. But, all his 4 ATP titles have come in the hard courts.
Kyrgios doesn't have a great record at the Shanghai Masters, exiting in the first round last year. His last tournament was the Japan Open where he didn't look too fit, exiting a few days back. He hasn't played all tournaments this year due to recurring hip injuries. Will they hamper him or can Nick Kyrgios pull out his usual bag of tricks? You'll know the answer in a couple of days time.
