The Bamburgh Castle player secured a spot at Muirfield with his 6 and 5 victory over Finland’s Toni Hakula in Saturday’s 36-hole final at Royal Cinque Ports.
“I think it will hit me next week when I realise I will be playing in The Open,” said the 23-year-old after becoming the first Englishman to win the amateur game’s blue-riband event since Gary Wolstenholme a decade ago.
“It is just over an hour away from my house so there will be a lot of local fans coming out to watch. I played Muirfield four years ago in The Amateur and it will feel pretty special to tee it up there in The Open.”
Having also won the Scottish Open Stroke-Play Championship at Southerness last month, Porteous has surely sealed his place in the Great Britain & Ireland team that will defend the Walker Cup later this year.
“It’s quite a surreal feeling right now,” he added after also securing invitations to next year’s Masters and US Open.
“I know there are a lot of famous names on that trophy. To be alongside them is pretty humbling. I felt confident coming into the week but I never got ahead of myself. I just played one shot at a time and it worked.”
As winds gusted up to 40mph on the Kent coast, Hakula won the opening hole but was soon fighting a losing battle after finding himself four down at the turn.
“It hurts to lose and I feel like I didn’t play as well as I could, even though the weather was tough,” admitted the runner-up afterwards.
