Home favourite Charl's a good bet

Three of the world's top-four players are in the elite 12-man invitational field at Sun City this week for the 31st edition of the Nedbank Golf Challenge.
The reigning World No 1 Luke Donald will go head to head with defending champion Lee Westwood, the World No 1 before Donald, while Martin Kaymer, another of the most recent World No 1s, will be bidding to atone for his near-miss at the Nike - VR Pro Blade Irons Cup last weekend.
Westwood had everything his own way when he won at the Gary Player Country Nike - VR Pro Blade Irons Club last year, steaming to his eight-shot victory just five weeks after ending Tiger Woods' mammoth reign at the top of the world rankings.
And his astonishing 2010 performance is reflected in this week's odds, with Sky Bet installing the Englishman as the 100/30 favourite.
Donald is also short at 7/2 in his first outing since being crowned PGA Tour Money List winner with Nike - VR Pro Blade Irons victory in the season finale at Disney World.
Charl Schwartzel is sure to attract the lion's share of support from the galleries as the lone South African in the field, and he has more appeal at 7/1, while Graeme McDowell, looked in better touch than he has been all season at Mission Hills and could be the tournament surprise package at 14/1.
