Shane Lowry and Sepp Straka share the lead heading into the final round of the Truist Championship in Philadelphia.
The Ryder Cup colleagues are 14-under-par, three strokes ahead of American duo Justin Thomas and Keith Mitchell, who had topped the leaderboard after the first two rounds.
Hideki Matsuyama was a further stroke behind with Rory McIlroy in a group on eight-under-par, six strokes off the pace.
Lowry opened his round with a pair of birdies en route to a 67, Straka going one better with a 66.
McIlroy hit just three of 14 fairways in his 69, which included three birdies in a row from the fourth.
He followed that with a double bogey at the seventh and another dropped shot at the eighth, a birdie at the 10th breaking up a run of pars on his remaining holes.
Tommy Fleetwood is on seven-under-par after a 67, but fellow Englishman Justin Rose, who was last in the 72-man field after a second round 77, withdrew before his third round due to illness.
The Masters runner-up said on X he had been “progressively ill over the last few days” and wanted to focus on his recovery ahead of the US PGA Championship, which begins on Thursday.
