Northern Ireland's Rory McIlroy, who entered the final round of the US Open at the Congressional Country Club in Bethesda, MD with an eight-stroke advantage, birded his first hole, pared the second and third to move 15-under par. McIlroy now leads the field by nine strokes as Korea's Y.E. Yang and England's Lee Westwood each are at 6-under par.
Westwood began his final round with a birdie on No. 1, and pars on No. 2 and 3. On the third hold, Westwood's birdie attempt rimmed out. Yang has made pars on his first three holes.
Currently, the field is finding a lot of scoring opportunities. Two players who have taken advantage of Sunday's soft course are USA's Steve Stricker (-5), who has made five birdies to sneak into the top five, and defending British Open champion, Louis Oosthuizen (-4), who's 4-under par on the day.
Phil Mickelson finished his day at even-par and 7-over for the tournament.
