You can pinpoint the exact moment Dustin Johnson won the PGA Tour Player of the Year Award this season.
It happened on the 69th hole of the BMW Championship after Paul Casey had cut Johnson's lead to one stroke with an eagle. There were three holes left for Johnson to try and snag his third win of the season in addition to his U.S. Open and Bridgestone Invitational titles.
Johnson poured in a long putt for eagle on top of Casey to extend the lead back to three strokes and cruised home to the trophy and (more than likely) that Player of the Year award, which will be handed out after the Tour Championship in two weeks.
