no but can play a good match
Well I think the only thing that would stand in Jonathan's way is his mental state because his game is far more explosive than Murray's. When Jonathan's power game is "on," he should blow Murray off the court, based on power. I know Murray is tricky, but with Murray's bad clay form, I can't imagine a better time for Jonathan to beat him. Then again these aren't going to be hard courts, where I think Jonathan's game is even more explosive and quick but I know. I hope Jonathan wins.
By the way, if anyone to see some his matches, like his Australian Open Boys Final from last year, go here: http://forum.jonathaneysseric.com/viewtopic.php?t=5
