DUBLIN, Ohio – Dustin Johnson waited 2 1/2 hours to hit one wedge shot from the fairway at No. 18, but it was worth it.
Johnson stuck his second shot to 2 feet for a closing birdie, a 4-under 68 and a great chance on Sunday to win for the first time since the 2015 WGC-Cadillac Championship.
Thunderstorms halted play just after 5 p.m. ET, and when the horn sounded at 7:30 to resume the third round Emiliano Grillo and Matt Kuchar were at 15 under.
Grillo promptly doubled the par-4 17th.
"On 17, I was ready to hit, and the official told me not to hit, and then they waited a minute to blow the horn," Grillo said after shooting a 2-under 70. "So I'm kind of pissed about that, but it is what it is."
Grillo, Johnson, Adam Hadwin (67) and Jon Curran (68) are all one stroke off the lead held by Kuchar (70), William McGirt (64) and Gary Woodland (69).
Kuchar saved par at 16, missed a 10-foot birdie putt on 17 and bogeyed 18 to finish tied at 14 under.
"I've had a lot of success here, having a win back in '13," Kuchar said. "I'll certainly be looking forward to tomorrow's round of golf."
