The heat and humidity have settled in on the east coast. This will be hard for any player to dominate. Additionally, the hurricane season is predicted to be active, which could again cause impacts to USO. Watch for players to request evening matches, in particular Novak. I imagine he has 2 goals, Cincy and USO. It should help Roger's back, but even the heat can't fix a back issue if he can't get it healed. Rafa will sweat buckets and like playing in the sun. Not as much as he does if it were clay. Should his fitness be off, expect a lousy hard court swing. Who knows goals are regarding the hard court swing. I'm not sure how much Andy trains in the heat in Miami, but I think the heat will favor him more than the others. I tend to wonder about the up and comers like Jerzy, who have played more than previous years and whether the number of matches may catch up with them. It will also be interesting to see if Gulbis brings it during the hard courts, given his new attitude this year or if he achieved his rankings goal and is back to partying. I think the hard courts are going to be harder due to the heat and humidity that has settled in.
