Padraig on target for $1m payday
Harrington carded two birdies over the first eight holes of the Sherwood Country Club to stay on 21 under par, four ahead of Woods who had shot four birdies to bring the Irishman slightly closer with a potentially troublesome back nine looming.
But it was on Saturday that the Irishman did most of the work to fashion this victory, when he shot three eagles and nearly made another en route to a course record nine under par 63 and a six-stroke lead.
