(REUTERS) - Spain's Jon Rahm clinched his second Irish Open golf title with an impressive final-round eight-under 62 to seal a two-shot victory on Sunday (July 7).

The 24-year-old started the fourth day at the Lahinch Golf Club in County Clare five shots behind overnight leader Robert Rock but eight birdies and an eagle on the 12th hole catapulted him to the top of the leaderboard.

His fourth-round score, which took him to 16-under 264 for the tournament, also tied his lowest European Tour round and was a huge turnaround in form after he carded 67, 71 and 64 in the first three rounds.

"My game was in great form, it just didn't show the first two days. I couldn't hole the putts," Rahm, who also won in 2017, said.

"The weekend was the complete opposite, putts rolling in from everywhere. I felt really confident and I knew I could do something. I knew I had to do it to have a chance.

"I kept looking at the leaderboard and looking up and after 10 I'm like, 'okay, let's get a good run'. And that eagle on 12 just got me going."

England's Andy Sullivan and Austria's Bernd Wiesberger, who were both tied for fifth after the third round, finished second two strokes back after identical rounds of 66.

Rock had a day to forget after his record-breaking 60 on Saturday, finishing tied for fourth with compatriot Eddie Pepperell and Spain's Rafa Cabrera Bello on 267, with an even-par score in the final round.
