Couples comes off a runner-up finish in California last week so the chances of him successfully defending are very good.
Bernhard Langer has recorded 1st, 2nd and 3rd place finishes in three of his four starts this season and is expected to be Couple's greatest threat .
Peter Senior finished off last week's Toshiba Classic very well and finished 3rd. Senior played this event well last year when finishing 10th and if this week was to be the one for the big breakthrough then it would be well overdue.
Senior, the 2012 Australian Open Champion, has played just three events this season earning US$150,000 in the process.
