Ernie Els, who entered the day in a tie for fifth, also shot 72 to drop to a tie for 17th at 8 under.

Glover birdied the eighth and ninth holes to get to 14 under, and opened a three-stroke lead at 15 under with a short birdie putt on the par-5 11th. But he failed to make par from the fringe on the par-3 14th to drop back to 14 under. He missed a 10-foot eagle putt on the 18th hole and tapped in for birdie.
The players will be grouped in threesomes and will tee off early because of expected stormy weather Sunday on the course already softened by heavy rain Wednesday.
