Squash TV is recently publishing a lots of hot shots and mega rallies on their youtube channel. I am picking the below one because I think it demonstrates two things I would like to mention:
1) the great potential that Simon Rosner has got; notwithstanding his big size, it is very impressive how well he moves, and especially how quickly he can get back from big lounges (generally a tough thing for tall players). He is also an excellent reader of the game, he is by now really very close to the top8 in this regard.
2) But to get there I really think he has to modify one thing: his huge backswing.
Watch this rally and observe how many times he lacks precision and accuracy exactly because his backswing requires too much time to prepare which makes him hit the ball a fraction too late. As long as he's got time and space, there is no problem with this kind of racket preparation, but as soon as you lack one or the other factor, you will struggle to hit precisely. This is mostly evident in situations when the opponent hits a slightly loose but quick straight ball as we can see it in this rally at 0:16 and especially at 0:23; in both cases Rosner hits late and this is why the ball finds the sidewall.
Of course, in certain situations this big swing favours Rosner, like when he is going for his trademark low cross-court kills in the front, but in situations around the 'T' he will need to study the top guys' swing, to start with the most compact one probably: Karim Darwish.
Will Rosner be able to adjust in this technical regard, then I feel there will be very little to separate him from the top10, or even the top6.
Oh, and just to mention also the obvious before we finish: what a beautiful carousel rally this was! Unlucky for the records that it had to end with a 'Stroke'.
