Open champion Padraig Harrington leads US Open champion Angel Cabrera by one shot with six holes to go in the four-man 36-hole PGA Grand Slam at Mid-Ocean in Bermuda today.

Harrington, one in front after his opening 67, was five clear when he resumed with a birdie three against Cabrera's triple bogey seven. But the Dubliner saw that disappear when he double-bogeyed the ninth and Cabrera started for home birdie-eagle to catch him on three under par.

Cabrera then bogeyed the next to fall one behind.

Jim Furyk was only two behind thanks to an outward 32, but he then crashed to a triple-bogey eight on the 11th, allowing Masters champion Zach Johnson to go into third place one one-over.

First prize is €500,000 and Furyk is playing because US PGA winner Tiger Woods turned down the tournament.

Harrington is the first European to qualify for the event since Paul Lawrie and Jose Maria Olazabal in 1999.

Ian Woosnam is the only European to win the title — back in 1991 when he was up against John Daly, Ian Baker-Finch and Payne Stewart.
