Tiger Woods posted a career-worst nine holes at the Memorial Tournament in Ohio.
Woods shot an 8-over 44 on the back nine during the third round and, typically, declined interview requests after the aberration.
He spoke later to a PGA Tour official.
"The conditions were tough and when I missed it cost me," he said after completing a 7-over 79 at a venue where he has won five times. "I caught the wrong gusts at the wrong time, made a couple bad swings and all in all it just went the wrong way."
The 37-year-old's previous worst nine-hole score was a 43 on three occasions, most recently at Quail Hollow in 2010.
Matt Kuchar retained his third-round lead to win at Muirfield Village.
