Kyrgios - still to deliver

For all the controversy surrounding talented young Australian tennis player Nick Kyrgios, and those that are willing to forgive his regular indiscretions because of his on court feats, his achievements have really not been that special.

Yes, for a nineteen year old, the fourth round win over Nadal last year at Wimbledon was memorable and perhaps a portent of future success, but his output since has been anything but stellar.

Nick has yet to break into the world top twenty - in fact is still only the number two ranked Australian. His 2015 was jump started with a quarter final result at the Australian Open, and all kinds of predictions  were being thrown around for his rise in the game.

However, his only success against players ranked in the top twenty have been wins against Federer and Raonic, both great triumphs but immediately followed by disappointing losses to Isner and Gasquet respectively.

Six of his eleven losses for the year have been to players in the top twenty, while 14 of his 16 wins have come against those ranked 27 or lower.

No one can reasonably deny the promise of Kyrgios, and the probability that he will eventually realise much of his potential, but to continue to be accepted with all his faults, he does need to deliver some on court success beyond the occasional great match.
