No of course it isn't. Try Googling "The Masters" / "The U.S. Masters 2009" etc etc, and somewhere in amongst it, you'll find details of the prize money.
For example, the winner go $1,350,000.
It breaks down the prize money as far as last place, i.e.50th who got $18,900.
I know Sandy Lyle finished 2 under par but am not certain exactly what position he finished.
At a rough guess, he was around 25th place which would have netted him about $66,000.
