US Open Upsets

What contributes to an upset?

• Did you know they resurface the courts every year changing the Sand mixture.
• High Winds
• Court Tempatures
• Rain Delays
• Did you noticed Federer used body shots on his serves more than he use to.

Was Federer playing different because nothing was working or was he off on his judgement/reading of the ball giving him different results.

More and more people say he needs to retire.

• Are you going to retire Nadal, Djokovic, Murry too???

SOmething to think about while it is raining here in NC.
