Rory McIlroy, comfortably in the fairway at 12, held a one-shot lead when the horn went off at 1:15 p.m. ET due to lightning. Play is now scheduled to resume at 5:15 ET., which should give them just enough sunlight to complete the tournament before darkeness.

The forecast was for more wind and enough rain that the PGA Tour moved up the tee times to send players off in threesomes from both sides Sunday morning. J.J. Spaun leads the tourney by a stroke.
