"Pretty crazy. It's been a fantastic start to my career," Scheffler said.
In addition, all of those victories came in the last four years and now that he has reached 20 in total, Scheffler will receive a lifetime membership on the tour.

Ludvig Åberg withdrew from the tournament after two days due to illness. The trio of Alex Norén, Jesper Svensson and Pontus Nyholm missed the cut.
