Masters champion Adam Scott
fired a course-record 64 to claim victory at the PGA Grand Slam of Golf in Bermuda.
US Open winner
Justin Rose had
a two-shot lead
after the first round and was still ahead with three holes to play.
But Rose, 33, bogeyed the 16th in carding a 69 while Scott, also 33, eagled the 17th to win by two shots.
US PGA champion Jason Dufner
finished five shots behind Scott with Padraig Harrington, playing in place of Phil Mickelson, another six strokes back.
The 36-hole exhibition is for the year's four major winners, but
Open champion Mickelson
opted not to compete.
Irishman Harrington won the event last year after stepping in for Ernie Els.
