Adrian Meronk produced a brilliant scoring burst to claim the Horizon Irish Open and become the first Polish winner in the history of the DP World Tour.

Meronk birdied the 15th and 16th and then holed from 25 feet on the par-five 17th for an eagle as he carded a closing 66 to finish 20 under par at Mount Juliet, three shots clear of New Zealand's Ryan Fox.

South Africa's Thriston Lawrence finished third on 16 under, with Scotland's David Law, American John Catlin and Paraguay's Fabrizio Zanotti sharing fourth on 15 under to claim the three places on offer in the 150th Open Championship at St Andrews.

"It's such a relief, to be honest," admitted Meronk, who had recorded three top-three finishes in his last six starts.

"I've been coming quite close a couple of times this year and to finally open the door is just a dream come true. That's why we practice every day and I'm super happy."

Asked about being a role model to a generation of Polish players, Meronk added: "I love it, I love it.

"I'm not stopping, I'm gonna keep going forward and it's just another step for me. I'm super excited (to win) here in Ireland, such a great history. I can't describe it.

"I was imagining this picture yesterday, what it might look like and it looked exactly how I imagined it and it was an unbelievable feeling. To hit such a good shot on the last hole, I'm super proud of myself and my caddie."

Fox had earlier set the clubhouse target after a closing 64, the in-form Kiwi following four birdies on the back nine with an eagle on the 17th to briefly enjoy a two-shot lead, only to bogey the last after firing his approach over the green.

"The shot on 18 was pretty much the only bad shot I hit today," Fox said. "Happened to be in between clubs, went for a draw and pulled it a little bit.

"It's been a weird week really; shot 64 in the first round, didn't miss a shot, and then the same today with a little bit of scrappiness in the middle.

"I got off to a little bit of a slow start today, made a couple of nice birdies on four and five and then got hot with the putter on the back nine."

Speaking about securing his place in the Open, Law said: "Unbelievable. It's a dream come true. I've never played a major before. To have my first one at St Andrews will be a bit amazing.

"I think my mom and dad actually have a holiday booked that week. Whether that gets cancelled or they go or what (I don't know), but it will be a dream come true to play, especially at the home of golf."

Shane Lowry played his way into the top ten with an impressive final round 67 to end the week in a share of ninth place.

Two birdies on the front nine saw Lowry turn in 34, before he got to four under for his round with back-to-back strokes gained on ten and eleven.

A solitary bogey arrived on the 12th hole, before the 2019 Open champion picked up two more birdies on the 14th and 17th to end the tournament on 12 under par.

Seamus Power also moved up the leaderboard, bouncing back from his disappointing Saturday by ending with another 68 – his third of the week with his third round 77 ruining his chances of competing in the final round.

Three birdies and an eagle on the par-five eighth hole for Power with just the one dropped shot in his round coming on the sixth hole as the Waterford man ended in a tie for 30th.

Joining Power on seven under was Padraig Harrington, who posted his fourth consecutive under-par round, ending with a 69.

It could have been so much better for the three-time major winner as Harrington opened with five birdies in a row and added a sixth on the eighth hole, turning in 30.

But a double bogey seven on the par-five tenth stopped Harrington in his tracks and two more dropped shots would follow on 16 and 18, his only other birdie coming on 17.

Niall Kearney shot two under to end the tournament on four under in a share of 58th place.
