The final day of the tournament featured the Sunday Singles matches, with Tommy Fleetwood clinching the needed half-point to win the tournament for Europe.

However, there was a reported argument between Rory McIlroy and Patrick Cantlays caddie, Joe LaCava, on the 18th green during the Saturday Four-ball matches. The argument appeared to be related to LaCavas behavior, which McIlroy found disrespectful.
