Reigning Open Champion, Phil Mickelson has elected not to contest this year’s elite four-man Grand Slam of Golf.

Instead Mickelson’s place will be taken by defending Grand Slam of Golf champion, Padraig Hafrrington.

So this year’s event will now feature – Masters Champion Adam Scott, U.S. Open Champion Justin Rose, PGA Champion Jason Dufner and Harrington – in the  event to be take place from October 14th to 16th at Port Royal Golf Course in Bermuda.

Scott, Rose and Dufner will make their first appearance in the PGA Grand Slam of Golf, while Harrington is making is fourth visit to the Island. Harrington won last year’s event and finished runner-up in 2007 and ’08.

Mickelson indicated he will be unable to compete due to an end-of-season scheduling conflict.

The defending champion of the PGA Grand Slam of Golf receives the initial invitation if a current major champion is unable to compete; then the Major Champions Points list — which charts the performance throughout the year of active major champions — is used to complete the field.
