The back nine on Sunday will be where the true contenders emerge as they strive to join - or cement their membership of - the elite club of 44 Masters champions.

There have been 28 one-time winners, nine two-time winners and four three-time winners. Tiger Woods and Arnold Palmer have four victories each and Jack Nicklaus tops the charts with six titles.

Unless he wins again, Trevor Immelman will have one last duty to perform as defending champion in presenting the 2009 winner with the coveted Green Jacket.

The major circus then rolls on to the US Open at Bethpage, New York, from 18-21 June.
