LEADERBOARD

Riley is at 14-under and he'll be pursued by Scottie Scheffler, who moved into second place with his bogey-free 63 in the third round. He birdied three of the past four holes in what marked a return to form following the chaotic off-course drama from a week earlier at the PGA Championship.

There was a stunning tone around the third round, when the announcement came that PGA Tour player Grayson Murray had died at age 30.

Riley, who led after the second round at 10-under following Friday's bogey-free 64, went eight more holes without a bogey Saturday.

Scheffler's third-round score was three shots better than any other golfer.

Hayden Buckley (69) and Pierceson Coody (69) share third place at nine-under.

Robby Shelton's 67 moved him to eight-under so he'll also be in pursuit of the $1.638m winner's prize. Tony Finau (68) is sixth at seven-under.

Riley, who missed seven of 14 cuts entering the tournament, stretched his lead to five shots on Coody through eight holes with birdies on five holes in theround to that point. Even after a bogey on No 9, his lead was at six strokes.

After another bogey on the 10th hole, Riley was steady the rest of the way by going one-under for the final eight holes.

Defending champion Emiliano Grillo of Argentina shot 73, dipping into a tiefor 69th place at five-over.
