Open champion Padraig Harrington leads by one shot after the first round of the two-day PGA Grand Slam of Golf in Bermuda.

The Irishman shot a three-under-par 67 with six birdies and three bogies at the Mid Ocean Club in Tuckers Town.

The four-man event brings together the winners of the year's four majors, apart from PGA championship winner Tiger Woods. Woods won last year's title in Hawaii by two strokes from fellow-American Jim Furyk.

US Open winner Angel Cabrera of Argentina is a shot behind Harrington while Furyk, who took Wood's place, is four shots off the lead along with compatriot and Masters champion Zach Johnson.
