Made a hole-in-one on No. 17 at Cragun's Dutch Legacy Course, sinking the 126-yard par-3, with a 52-degree wedge. His last hole-in-one was during a practice round for the 2019 U.S. Open at Pebble Beach. The ace turned out to be huge for Etulain, who shot 65 in the final round to move into a tie for sixth. As this was only his second event on PGA TOUR Canada, it moved him up to 64th in the points standings, but he still missed qualifying for the Fortinet Cup Championship.
