South Korea's Sungjae Im sank a 13-foot putt on the final hole to shoot a 69 and stretch his lead to two strokes after the third round ofthe Valspar Championship, with Séamus Power carding a 70 that sees him eight shots adrift of the leader.
Power posted three birdies in his round but dropped shots on eight and 16 saw him sign for a 70, leaving the Co Waterford player on three under.
Im had gone nine holes without a birdie on Innisbrook Resort and Golf Club's Copperhead Course before sinking his last birdie attempt. He enters Sunday's final round on 11 under, as he strives for a first PGA Tour win since the 2021 Shriners Children's Open.
Brandt Snedeker posted 67 to pull into a share of second place with David Lipsky, who turned in an erratic 70.
Snedeker's bogey-free round, beginning with three birdies on the first four holes, gave him a score that matched the best rounds of the day.
England's Marco Penge and England's Matt Fitzpatrick shot matching 68s to hold a tie for fourth place on eight under. That's two shots clear of South Korea's SH Kim and Belgium's Adrien Dumont de Chassart, a duo that shared the day's best round with Snedeker.
Lipsky moved into a share of the lead with a birdie on 15 before giving it back with a bogey - his third of the back nine - on the next hole. His round included five birdies and four bogeys.
Im, who hadn't led through 36 holes of a PGA Tour event since 2021, finished at 69 for the second day in a row. He saved par on 16 after a tee shot settled on a cart path.
Penge was at two over for the round after a double-bogey six on the sixth, but he played the backside bogey-free at four under.
