Since joining the tour in 2003, Mahal's best performance has been his 2003 victory at the New Zealand Open. Five weeks later he backed up that great performance with an equal third at the Jacobs Creek Open. Since then, Mahal hasn't been able to repeat those great performances until recently when he had two top 10 finishes in 2011 at the NSW and New Zealand Opens, where he finished 5th and equal 9th, respectively.
