Hadwin, from Abbotsford, B.C., will finish the year in the top 50 of the world golf rankings, guaranteeing him a berth at the prestigious annual tournament.
Cam Smith could have knocked Hadwin out of the top 50 with a two-way tie for third or better at the Australian PGA Championship.
Smith tied for 10th at the event on Sunday, keeping Hadwin’s spot at the Masters safe.
Hadwin did not compete in any tournament this week after playing on the International Team at the Presidents Cup.
Joining Hadwin are fellow Canadians Mike Weir (2003 champion) and Corey Conners (qualifier of 2019 TOUR Championship).
