The statistical certainity but unbettable tennis system has 7 selections for the US OPEN.

It takes Federer in Round 1 & 2 (seed1)

It takes Nadal Round 1 & 2 (seed2)

It takes Hewitt Round 1 & 2 (seed3)

It takes Roddick Round 2 only (seed4)

Interestingly seed 3 has not lost since 1978 (when my stats start) in the first round. so a 100% statistical certainity???
