Lucas Herbert carded a 64 to take a one shot lead after a low scoring first day of the 2021 Dubai Duty Free Irish Open.
The Australian set the target from just the second group of the day at Mount Juliet Estate and while a host of Ryder Cup stars set about chasing him down, nobody could better his eight under par total.
American Johannes Veerman made a late charge in the evening to get to seven under, a shot clear of Scotland's Grant Forrest.
Ryder Cuppers Nicolas Colsaerts, Tommy Fleetwood, Martin Kaymer, Thorbjørn Olesen and Andy Sullivan were then all part of a 15 strong group at five under, with 55 players within five shots of the lead.
Herbert claimed a maiden victory at the 2020 Omega Dubai Desert Classic but has had just two top tens since, including at this event last season.
But his 64 in County Kilkenny was his lowest European Tour round since September 2019, and he enjoyed playing in a two ball with Laurie Canter after the withdrawals of Victor Dubuisson and Kristoffer Broberg.
"Made a really long one on 18 for birdie and that kind of sparked things and got things going," he said. "Was able to play really nice that last nine holes.
"I felt like I was trying to get to five or six under and I didn't really want to try and just attack really, really hard. It was just try and hit the ball in the right spots, give yourself some looks on the greens and I felt like if I could get to five or six under that would be a really good day.
"A few more rolled in and I got to eight.
"It's a little bit tight in spots as well where you're not taking driver and just sending it. You have to play to some positions.
"Second group out we were, the greens were unbelievable. I can't remember putting on greens that nice."
Was able to play really nice that last nine holes
Herbert took advantage of the par five tenth but gave the shot straight back before hitting a smart approach into the 15th, making a two putt birdie after leaving himself ten feet for eagle on the 17th and holing from nearly 30 feet on the next.
A 15 footer on the third was followed by another two putt gain on the fifth and a nice approach into the seventh before he completed the set of birdies on the par fives at the eighth.
A 15 foot putt on the ninth then left him three shots ahead but Forrest trimmed the gap.
He holed lengthy putts on the third and fourth and made the most of the fifth before missing a ten footer and settling for a birdie on the eighth.
A birdie on the 12th was given back on the 13th but two more lengthy putts on the 14th and 18th left him as the nearest challenger.
But, from the very last group of the day, Veerman leapfrogged Forrest with a bogey free effort.
He took advantage of all four par fours while also holing from 16 feet at the fourth, similar range at the 11th, and eight feet on the 14th.
Alongside the Ryder Cup quintet at five under were Spaniards Adri Arnaus and Sebastian Garcia Rodriguez, South African Christiaan Bezuidenhout, American Sean Crocker, Belgian Thomas Detry, Frenchman Grégory Havret, English pair Dale Whitnell and Andrew Johnston, Scotsman Richie Ramsay and Australian Jason Scrivener.
There were then 18 players at four under, one clear of defending champion John Catlin.
Crowds were back lining the fairways and a big gallery followed home favourite Shane Lowry who was two under, two shots clear of four time Major Champion Rory McIlroy.
