American Derek Ernst has climbed an incredible 1,084 places in the world rankings following his victory in the Wells Fargo Championship on Sunday.
Ernst, 22, has moved from 1,207th to 123rd on the latest standings courtesy of beating England's David Lynn on the first hole of a play-off at Quail Hollow.
Lynn has the consolation of moving from 64th to 42nd, while there was no change in the top nine places. Phil Mickelson, who bogeyed two of the last three holes at Quail Hollow to miss out on the play-off, moved from 11th to 10th.
Australia's Brett Rumford climbed from 122nd to 76th thanks to his second consecutive victory on the European Tour at the Volvo China Open, a rise of 177 places in two weeks.
