Toms only dropped one shot on his way to a 6-under-par 66, the day's best round in demanding, breezy conditions on the Quail Hollow course.

Charles Howell III moved into second place late in the round before bogeying the 16th and 17th to end the day six shots behind. He had played 51 holes without dropping a shot.
