Birthday kid Rory McIlroy checked a three-under-standard 68 to stand two shots back going into the last round of the Wells Fargo Title.
Americans Max Homa (70), Joel Dahmen (70) and medium-term pioneer Jason Dufner (71) are tied for the lead on 11 under following a downpour hit day at Quail Empty.
Pat Perez (66) is a shot behind, one stroke in front of Northern Irishman McIlroy, who turned 30 on Saturday.
Britain’s Justin Rose (68) is on eight under with Paul Casey (66) seven under.
Ireland’s Seamus Power (69) is additionally seven under, while Spain’s Sergio Garcia is among five players on six under after a 66.
“This fairway truly remunerates tolerance and prized discipline. I have a feeling that I was both of those today,” said McIlroy.
The two-time Wells Fargo champion was five shots uncontrolled toward the beginning of play on Saturday and grabbed one shot on the front nine.
McIlroy made three birdies on the back nine, with an intruder on the twelfth, to complete the day on nine under.
