According to the article linked on the front page he's getting a "huge six-figure appearance fee", 50,000 euros for winning, and a 50,000 euro bonus for getting the WR.
The Euro is at 1.46 right now making the win and the WR together worth $146,370. That "huge six-figure" appearance fee is in euros so what do you think that's worth? 100k euros? 150k euros? 200k euros?
Assuming the lowest possible figure of 100k for appearance, plus the purse and the WR bonus, he stands to make:
293,000 (minimum)
For some reason that seems a little low. I'm guessing the appearance fee is another 50k higher putting him closer to $400k for the day. Just a thought.
