For all his returning prowess, Nole does seem to struggle more against the bigger servers. Guys like Fed and even Murray seem better able to put them in the akward mid-court on return.
That said, huge performance from Raonic....his groudie reliability and movement are really coming on....he can moosh the ball. Things heating up on tour!
Novak returns way too aggressively against them, imo. Murray and Federer focus on getting it back and starting the point and letting their superior rally skills take over.
