The final major of the year was held at L'Empereur and was to be hosted by Nic, but due to illness, Nic was forced to withdraw.
Jeff applied some early pressure, but Icaro never really got anything going. While their handicaps kept them within reach on the front 9, Jon kept putting up pars and bogeys to start pulling away by the turn.
It was the back 9 where Jon really pulled away. 3 pars and 3 bogeys along with 2 birdies in the last 4 holes - including a curling 30 footer on the 18th - gave Jon the title and set the record for the lowest round ever shot in a Major.
Jeff and Icaro both played about the same and ended the round tied for 2nd.
The victory gives Jon his 9th career major and is the first time he has won multiple majors in the same calendar year. It also clinches his 2nd McGasparson Cup - the first since 2010 - as Nic will be unable to get enough rounds to qualify.
The sensational round dropped Jon's handicap to 13.8, the lowest ever on Tour. Icaro and Jeff each rose 0.1 to 19.3 and 21.2, respectively.
