Four-time major winner Rory McIlory has stormed into the lead of the US Masters during the third round at Augusta National. 

The Northern Irishman shot four-under on the front nine on Sunday morning, AEST, to be 10-under for the tournament. 

Playing partner Bryson DeChambeau was outright second at eight-under. 

McIlroy made a blistering start with three birdies and an eagle in the first five holes. 

The front nine could have been much better for McIlroy, but he finished the first half of his round with a bogey at the eighth and a missed birdie putt at the ninth.

Australian Jason Day was well in the mix, sitting at three-under through 12 holes, to be five-under for the tournament. 

The Queenslander has three birdies and no bogeys through a dozen holes.

Englishman Justin Rose, who started the day with a one-shot lead, shot one-over par for his first nine holes.

West Australian Min Woo Lee had a rough day and fell out of contention, carding four-over par to finish the day at three-over for the tournament.
