Mayfair leads, McIlroy four off pace in Quail Hollow

Billy Mayfair remains on course for his first PGA Tour victory since 1998 heading into the final round of the Quail Hollow Championship in Charlotte.

The 43-year-old, who was four under in each of his first two rounds and led at halfway, carded three birdies and two bogeys for a one-under-par round on Saturday to leave him two shots ahead of Davis Love III and Phil Mickelson after 54 holes in North Carolina.
