"Whether you're the favorite or the underdog, I think I've proved this year that anything can happen," Grace said.
The Nelson Mandela Championship is the start a jackpot year for South Africa on the European Tour. The country will host six tournaments in the Race — the most ever — with the addition of the Nelson Mandela, the Tshwane Open and the retention of the Volvo Golf Champions.
The Tour starts with three straight in South Africa.
South Africa will introduce the $8.5 million Tournament of Hope at the end of 2013, the second-richest tournament in golf alongside the four WGC events and just behind the Players Championship.
The Tournament of Hope is not a European Tour event, but it will give South Africa back-to-back big-money events alongside its European Tour schedule if the Nedbank Golf Challenge invitational at Sun City stays in its regular slot.
