In 2017, Portstewart hosted the Dubai Duty Free Irish Open, from 6–9 July for the first time in the club's history. This was by far the biggest tournament the club had ever hosted and attracted crowds of 92,000+ for the whole week. The young Spaniard Jon Rahm took the title and shot an Irish Open record score of 24 under par for 4 days. David Drysdale broke the course record for The Strand Course by carding a 63 on the final day.
