Compare these three please
Who will have the more successful pro-career?? See them winning grand-slams??
These three have similar playing styles, similar height, penetrating ground strokes and yet they don't venture into the forecourt and don't use their height and reach to their advantage
Del Potro'serve is atrocious to say the least
You are lost my friend.
DP's serve wasn't good last night because he was injured, kicking off his leg just wasn't working but generally he has a good serve. There's a very good chance that Del Potro can be a big player.
Cilic has a lot of potential, no doubt about that.
Querrey? Querrey's not in the same league imo. Furthermore he's older than the other two guys. It's almost like a thread asking who is better, Nadal, Djokovic or Berdych.
I'd expect Del Potro and Cilic to at least compete at the top of the game, probably be top 10 players, Querrey, not for me.
