Now that Federer is out...

[Conqueror]

Who wins the US Open?
Going with Del Potro here.
Nadal would win this on clay court. But this is hard court.
Don't see either Anderson or Carreno-Busta winning a grand slam anytime soon.

Still think Rafa takes it. Rafa should exploit that WTA level backhand and won't make dozens of UEs like Fed did.

[Brooklyn Dick]

Federer far from top form. First two matches against low players showed that.

Nadal will beat Del Potro. The court playing slow favors Nadal, as it becomes more similar to clay for speed. Nadal will pummel Del Potro's backhand with heavy forehand topspin.
