Padraig Harrington leads Grand Slam of Golf

Padraig Harrington has opened up a two-shot advantage after day one of the Grand Slam of Golf.

The 41-year-old was a late replacement for Ernie Els and he made full use of his inclusion to fire an opening-round 66 in Bermuda.

US Masters champion Bubba Watson is in second place after a three-under-par 68, with Webb Simpson a further shot back in third place.

Defending champion Keegan Bradley could only shoot a round of one-over-par to end the opening day six shots off the lead.
