Tacoma (United States) (AFP) - Rory McIlroy was making a US Open charge at Chambers Bay during Sunday's final round.
Starting the day eight back of the quartet of leaders, the world number one had six birdies through 13 holes and had moved to within two of the lead.
The four leaders had just started out at that point and the first to blink was Masters Champion Jordan Spieth who three-putted the first to fall back to three under.
His three co-leaders - Dustin Johnson, Branden Grace and Jason Day - all parred the first hole.
Also moving up was Australian Adam Scott who was at level par after three birdies through 10 holes.
