"Typically, I always have a base layer and a ski cap coming here and make sure my rain gear is packed," Kuchar said after finishing the rain-delayed third round just before sunset.
Thunderstorms delayed Round 3 for about 90 minutes, and with more electricity expected on Sunday afternoon, officials will send players in threesomes of Nos. 1 and 10 between 8:30-10:30 a.m.
Notable final-round tee times (all starting on No. 1 tee)
10:20 a.m.: Adam Hadwin, Dustin Johnson, Jon Curran
10:30 a.m.: William McGirt, Gary Woodland, Matt Kuchar
