Was watching Del Potro vs Rochus replay and I have to say WTH is that? How can he win any service game with that...thing?
He serves an average of 100 and sometimes would serve at 95 mph, 95 MPH
, that's not even WTA level, girls today serve at what? 100-1005 mph? I know he is short but come on, he is a guy, an athlete, he sure can serve much much harder or at least put some spin on his serve, so what's his deal?
