And Nishikori has been pushing at the door - he has the talent but his body keeps letting him down. I'm pleased that he is the one of that grouping who has done best - so far at least.
Nishikori reminds me of Heather Watson. He plays well but is more a manufactured player without the magic spark of individuality that a Boris Becker, a Borg , and a McEnroe had or an Andy Murray has.
I never expected him to get to that level of a top three player. I doubt he will. The body will not allow it!
