American Bubba Watson claimed not to remember anything of the back nine after a playoff win saw him triumph at the 76th Masters at Augusta.
The world number 16 shot a birdie on the second playoff hole to beat South Africa's Louis Oosthuizen to the title.
"This day means so much more than putting on this Green Jacket, in many ways," said the 33-year-old. "But it is a special time to do it. It was amazing. The last nine holes, I don't remember anything."
The victory in Georgia was Watson's first Major of his nine-year professional career.
