Rahm stormed home with a closing round of 8 under 62 at Lahinch Golf Club to win by two shots, the Spaniard taking the title for the second time in three attempts.
Rahm’s round included eight birdies and an eagle along with two bogeys as he vaulted past the eight players ahead of him at the 54-hole mark to finish at 16 under while Bernd Wiesberger and Andy Sullivan shared second at 14 under.
The victory will take Rahm back inside the top ten in the world rankings and set himself nicely for the Open Championship in Northern Ireland in 10 days’ time.
When asked to explain the reason behind his success in the event (he also finished 4th in 2018) he was hard pressed to find a definitive answer.
“I don't know what it is,” said the 24 year old. “Every time we come, I just feel good all week. I feel so welcomed and so honoured to be supported by the Irish crowd the way I am, that I really want to play good in front of them.
“It's definitely a motivator in this event. It's very special to me, as a Spanish player, it was my first European Tour win and Seve's first European Tour win. Olazábal, Seve who won three times, and to become a multiple champion, it's an honour.”
When asked where he might now stand amongst those fancied to do well at Royal Portrush Rahm responded; “I'm not going to tell you if I should or shouldn't be on the top of the list. That's up to you. I mean, I would be honoured if I was considered. Still a lot of golf to be played. Still a lot of people coming over to play the Scottish. I'm playing good golf.
“I'm going into The Open Championship with a lot of confidence. It's the only major I haven't had a good performance at and I want to. It's a special one.
“I'm going to have a lot of good memories from The Irish Open in Portrush, because we stayed in Portrush when we played Portstewart. Yeah, good vibes, and hopefully the Irish crowd is as supportive as it's been in the last few years and I can make a charge.”
Wade Ormsby was unable to sustain the form he displayed early in the week and finished 19th but he finished as the leading Australian, recorded all four rounds in the 60’s and secured his second-best finish in his last nine starts on the European Tour.
Sam Brazel was the next best Australian in 50th place while Lucas Herbert, despite a final round of 65, could only manage 55th place.
The European Tour will now play this coming week’s Scottish Open at the Rennaisance Club in North Berwick before heading back across the Irish Sea to Portrush.
