Keith Horne finds himself in an unexpected position -- leading the Senior PGA Championship with 18 holes to go.

Horne, 54, fired a 5-under 66 during Saturday's third round to seize a one-shot lead over four players at Concession Golf Club at Bradenton, Fla.

Sitting at 11-under 205 is a surreal feeling for Horne, who carded six birdies against one bogey in his stellar third round.

The South Africa native has one Top 5 finish and $327,937 in earnings to show for his 14 previous PGA Tour Champions events. If he finishes on top Sunday, he'll add $540,000 and a major to the top of his resume.

'Of course, I'm surprised,' Horne said. 'It's such a strong field, such a quality field that's playing this week. It's not something we get to play in that often against the guys of this stature and quality. A lot of them are my idols. I watched a lot of them on TV.

'... It's not something I sort of planned or played for. I just try to stick to my own game, and I think that helped me today without looking around too much at what I'm leading.'

Thailand's Thammanoon Sriroj (66), Stewart Cink (70) and the Australian combo of Steve Allan (68) and Scott Hend (72) are the foursome tied at 10 under. Ben Crane (71) sits two shots back in sixth place.

Horne has spent most of his career playing overseas. He appeared in five Champions events in 2025, including tying for 28th at the Senior PGA Championship.

His best finish was a tie for 11th at the Principal Charity Classic. He made four of five cuts.

On Saturday, he had a bogey on his first hole before gaining the stroke back with a birdie on No. 3. Back-to-back birdies on Nos. 7 and 8 gave him momentum and he scored back-to-back birdies twice on the back nine during a five-hole stretch.

One thing Horne said he won't do on Sunday: track who's chasing him.

'No, I'm not a scoreboard-watcher,' Horne said. 'I think you get two types of people. I'm not the most confrontational person so, you know, I'd rather just stay away and just stick to my own game.

'I think if I look up and I feel like I need to chase or push or beat somebody specific, it doesn't help me. It only hinders me. I maybe just try too hard or put too much pressure on myself.'

Hend shared the second-round lead after rounds of 69 and 65, but he took a step backward Saturday with three bogeys over the first 11 holes. He rebounded with three birdies down the stretch to finish just one shot back.

He is well-aware the final round will feature a bunched-up leaderboard.

'Just stick to my game plan, play to my ability,' Hend said. 'If I play to my ability, then I've got a chance to win. If I don't win, then as long as I finish as hard as I possibly can, that's fine.'

Brian Gay, who shared the second-round lead with Hend, shot 2-over 74 shares seventh at 208. Also part of that tie are Fiji's Vijay Singh (67), Canada's Greg Owen (68) and Spain's Miguel Angel Jimenez (68).
