Oosthuizen looking to retain Open

Defending Open champion Louis Oosthuizen says winning last years' tournament has been an "inspiration" that he hopes can carry him to further success when the 2011 championship begins at Royal St George's on Thursday.

The South African world number 32 is hopeful of retaining his crown, but picks out Luke Donald, Lee Westwood, Rory McIlroy and Graeme McDowell as tournament favourites.

Oosthuizen has been paired in the first round with Martin Kaymer and Phil Mickelson.
