Rory McIlroy is attempting to follow up on his Masters triumph earlier this year with victory in The Open, which gets underway at Royal Portrush on Thursday morning

As the Open Championship returns to Royal Portrush, those who say Rory McIlroy shoot a record 61 around the course as a 16-year-old remember it as the day he went to "the next level" in his career.

The year was 2019. After a 68-year gap, the R&A took the Open back to Royal Portrush. The influence of major winners from Northern Ireland such as Rory McIlroy, Darren Clarke and Graeme McDowell was viewed as crucial in the decision.
