People from all nationalities descended onto the north coast to watch some of the golf’s elite navigate their way from tee to green.
Home dreams were crushed as Rory McIlroy failed to really get into contention as world number one Scottie Scheffler claimed the Claret Jug with a dominant four-shot victory.
It marks Scheffler’s fourth major title of his career and he is now just one away from completing the career grand slam.
