Nik Kyrgios.
Tennis has a rich history of 'characters'.
Prize plum he may be but you can't help but watch him, the match on now is riveting, he could win this or he could climb the umpires chair and strangle him with his tie.
Coco for me, she will dominate the women's game in around two years time
You would think so but not necessarily the case. Tracey Austin was only 16 when she first played Wimbledon and got to the semi finals but she certainly did not go on to dominate the game due to various circumstances.
However with Coco I think you might be right.
I don't think you'd ever get a mens player breaking through at such a young age as the physical difference between a fifteen year old boy and a man is much greater than a fifteen year old girl and a woman.
Boris Becker was 17. I don't know who the youngest male player at Wimbledon was without checking.
