People have been hyping Del Potro for a while now and looks like he's had some chances to finally show what he's made of. I saw his match against Haas yesterday and liked what I saw. Nothing too impressive but a solid game overall. A sligthly better serve and some touch at the net and he'd be "complete" but he needs weapons to compete at the top.
So question. Does this streak and wins over Roddick and Haas make Del Potro a top 5 contender for the USOpen along with Fed, Nadal, Djokovic, Murray? Or is he just a dark horse pick along with Gasquet, Blake, Berdych and such?
