Graeme McDowell, runner-up at the US Open a fortnight ago, does not want to be swept up by what is happening in his home town this week.
Portrush stages the first Irish Open in Northern Ireland for 59 years, but McDowell said on Wednesday: "It would be easy to get lost in the whole emotion of it.
"I want to enjoy it, but I want to enjoy it at the business end of things on Sunday."
He added: "I would rate winning this just outside the majors. It's about winning in front of your home fans.
"Northern Ireland has had its problems, but the town's buzzing and there's a sense of pride to see this great event here."
