If Andy Roddick beat Roger Federer in QF, I will pay you 50 bucks.
If Andy Roddick meet James Blake in the SemiFinal and win the SF over James Blake (only James, not any one else), your money doubles to $100.
If Andy Roddick win US OPEN, your price doubles again to $200.
This is for first 5 posters (who apply).
$200 X 5 = $1000. I be more than happy to pay 1000, if Andy Roddick surprise me with second US OPEN Title.
You should've started with: 'If Andy Roddick makes the QF, I will pay you $50.'
In all seriousness though, you can go ahead and spend your money on something else. Roddick isn't beating Federer if Rog was limping around on crutches. It's just NOT going to happen.
