Rory McIlroy and Darren Clarke will attempt to become the first European winner in 20 years at the 36-hole PGA Grand Slam of Golf event in Bermuda on Tuesday and Wednesday.
The event brings together the winners of the four majors so the two Northern Irishmen will be up against Charl Schwartzel and Keegan Bradley.
McIlroy played in China last week in a seven-day seven-city challenge event won by Lee Westwood.
This week's winner will earn £380,000.
The fourth and last finisher will still pick up over £125,000.
Ian Woosnam was Europe's last winner of the Grand Slam title when he beat Ian Baker-Finch, Payne Stewart and John Daly in Hawaii in 1991.
