Last time I checked the Hopman Cup was an actual event players wanted to win, especially Novak in his home crowd. I'm not saying Serena could compete against Novak or any Top 200, but she aced him twice, and if you didn't want to count the first one that's fine, but she did ace him again, and he didn't look happy by his body language facing the wall with his head down.
I would agree with you, any player will destroy the WTA players, but when it comes to Serena she has to be ranked between 400-300...there's a reason she beats her opponents, and sometimes so viciously.
home crowd? it takes place in perth
anyway, what is an ace?making ONE ace doesnt make you win a match
yeah she could ace some players, maybe many of them, but she wouldnt get a close set to players ranked into top 500, thats for sure
she wouldnt be ranked 300-400 on atp, the difference between movement and strength is so big, atp players play with lot of top spin and would move a lot serena and dont let her hitting all the time in the middle on the court. serena wouldnt overpower atp players on top 300-400, trust me
