Shane Lowry and Padraig Harrington moved inside the top ten of the at the Omega Dubai Desert Classic ahead of Sunday's final round.
Offaly native Lowry made a big move after posting a flawless five-under-par third round at the Emirates Golf Club.
The 2019 Open winner moved 23 places up the leaderboard to share tenth place following his impressive shooting, posting five birdies and no bogeys to sit on seven under par.
Harrington also made a positive move up the rankings with a solid three-under 69 as the Ryder Cup captain joined compatriot Lowry on seven under in a share of tenth place.
The Dubliner also managed five birdies around the Dubai track, however, handed two shots back with bogeys on the ninth and 13th holes.
England's Paul Casey took control of the tournament with a bogey-free eight-under 64 to top the leaderboard on 15 under, one shot clear of Scottish prospect Robert MacIntyre.
Casey put himself in pole position to boost his Ryder Cup ambitions with a birdie-eagle finish after admitting this week that making a fifth appearance for Europe later this year is at the forefront of his mind.
He made five birdies in his first 10 holes and then broke a run of six pars with a chip-in at the 17th. A remarkable second to 10 feet at the par five 18th set up a closing eagle, and Casey is taking inspiration from 47-year-old reigning Race to Dubai champion Lee Westwood as he looks to stay at the very top beyond his 40th birthday.
"We always say, if you stay the same level you're going to go backwards in this game and every year it gets better and better and better, every year the young guys come up longer and stronger and they putt it better," he told europeantour.com.
"There’s no question that I’m lucky that my physical attributes have allowed me to maybe give me another five years.
"Westy is inspiration. I saw him this morning. He was looking fit. I’ve still got to chase those guys."
South African Brandon Stone was at 13 under, three shots clear of Sergio Garcia – who won this event in 2017 before going on to win his first major at the Masters – and England’s Laurie Canter.
