Ernie Els unhappy despite enjoying late surge
Despite carding a closing 65 to finish 11 under par, Ernie Els joined in the criticism of the US PGA officials. A torrential downpour saw play suspended at 12:53pm local time, more than two hours before the final pair had been scheduled to tee off.
Play was eventually able to resume almost two hours later with McIlroy and Austria's Bernd Wiesberger starting at 4:19pm, meaning they faced a race against time to finish before darkness descended in Louisville.
Els said: "The boys are a bit unhappy. It could have been better organised. There were a lots of guys stuck out there.
"Me and Jimmy Walker were on the second hole and it was coming up to our ankles. The official told us to stay put but we crossed the fairway to get cover under the trees. Then when we heard the hooter, we just walked back.
"I was just talking with my caddie and (Rory McIlroy's caddie) JP Fitzgerald; we've never seen anything like it."
Els added: "On nine I said to my caddie let's get to 14 under. I felt my game was in such good shape," said the four-time major winner.
"The course was as gettable as you're ever going to get, as gettable as a Major course will ever be."
