A lot of players try to intimidate in some way with fist pumps and come ons. Roddick just doesn't do it subtly. If someone retaliates then there would be some much needed excitement in men's tennis. I didn't notice that he only picks on 18 year olds. How old is big muscular Ljubicic? How old is big muscular Tsonga? This I don't give a sh-- behavior is making me LOVE Roddick even more.
