I actually watched Hewitt and The Gucc live when Fed and Stan came down to Sydney for the Davis Cup tie on grass. They ended beating Fed and Stan. But I think Hewitt's volleys is a very underrated shot. His style is a baseline counter puncher but he plays the volley very well. I'm pretty sure he had really good numbers at net when he played Janko at AO. It may not be that surprising that he won a Wimby title.
