Welshman Jamie Donaldson will take a one-stroke lead into the final round of the Irish Open after a three-under-par 69 on Saturday.
The 36-year-old Welshman, ranked 116th in the world, has not won a European Tour event in 254 attempts.
But his third-round efforts have put him in with a chance of breaking that drought at Royal Portrush Golf Club, County Antrim.
Donaldson started his third round with a bogey, before an eagle on the par-five second hole put him back on track.
He sunk birdies at five, six and nine, together with a bogey five at the seventh, to build a two-shot lead by the half-way point of his round.
A third bogey of the day at 12 threatened to cost him the outright lead, but he recovered with a fourth birdie of the round at 16.
Donaldson is a stroke ahead of England's Anthony Wall, who carded a five-under 67 to claim outright second at 11 under.
Ireland's Padraig Harrington and Mark Foster of England are tied for third on 10 under.
Another Englishman, Paul Waring, is a shot further back, outright fifth at nine under.
And four players hold a share of sixth on eight under, including Denmark's Thorbjorn Olesen and Rafael Cabrera-Bello of Spain.
World number two and local favourite Rory McIlroy hit a one-under 71 to move to six under, tied for 11th alongside 14 others including Australian Matthew Zions.
Overnight leader Gregory Bourdy had a dismal day at tournament, carding an eight-over third round of 80, which included a double-bogey on the 12th hole and a triple-bogey on the 17th.
That nightmare effort saw the Frenchman plummet 29 places to tied 30th at four under.
