I'm willing to bet that Stevie gets a base salary and then gets bonused depending on where Tiger finishes....and I'm willing to bet that his bonuses at majors is greater than regular tour events. I'd have to think that most of the top players who have caddies that have been with them for a while have similar arrangements. As i recall, one of the reasons Fluff McCowen(Furyks caddie) was fired by Tiger was for revealing what he was getting paid.
