He signed a deal with Moet & Chandon in December for $30 million over 5 years. First deal he has done with Godsick since leaving IMG actually.
$76,014,777 in prize money to date. Deals with Rolex, Credit Suisse, Lindt and Mercedes. From all my research I'd say his net worth is like $300 now. Probably more. Plus his apartments in Wolerau and Dubai will be worth a bit too. And who knows what interest rate he gets with Credit Suisse :P
No doubt now him and Godsick are working away from IMG there will be more sponsorships and endorsements in the pipeline. Including more exhibitions.
