wasn't there an article in tennis magazine a while back about a computer rated 4.0 player playing a match against some 14 or so year old junior girl? He got beat like 1 and 0. Ok, 4.5 will easily beat 4.0 as well, but let's just say that Radwanska is perhaps a tad better than 14 year old junior, no? On the side note - all those folks claiming that the serve alone of 4.5 would overpower Radwanska. First - have you seen 4.5 serving in a real match for points? You may get a decent serve here and there, but if you claim you can ace her why can't you consistenly ace your league opponents? i mean it's not like her reflexes are worse than those league players. Second, what are you going to do after she returns your serve? Because if you think you can consistenly hit a winner off that return than again, why don't you do that against your 4.5 opponents?
