Keegan Bradley kept his lead at the Byron Nelson, but after firing a two-under 68 on Saturday, his lead is shrinking.
It was a hot day on the course, and scoring conditions were tough on the fast greens. As a result, no one made a big move up the leaderboard in the third round.
However, after Bradley began the day with a three-shot lead, he ended it with just a one-stroke advantage.
Sang Moon-Bae is stands alone in second at 12-under.
Meanwhile, Scott Piercy and Tom Gillis sit at 10-under and eight golfers are within five strokes of the lead.
Have a look at the leaderboard, and then I'll recap Saturday's action.
Bradley looked intent on slamming the door early on this tournament as birdied No. 3 to move to 12-under with a solid approach and wonderful putt:
However, Bradley quickly gave the field some hope as he bogeyed holes Nos. 5 and 6 to fall to 10-under. As we've seen with Bradley, a few bogeys does not mean he is falling apart.
After all, he had two bogeys on Thursday went he set a course record by carding a 60. Bradley birdied Nos. 7 and 9 to finish the front at one-under and hold a comfortable lead at 12-under.
The 18th hole continues to plague Bradley. His tee shot almost landed in the water and it was close enough to a rock that he merely had to chip into the fairway.
He was not able to get up and down, and for the third straight round he bogeyed the closing hole.
Still, Champions Tour golfer Larry Mowry loves Bradley's chance to take this event wire-to-wire:
If he does pull this off, he will be the first wire-to-wire winner of this event since Tom Watson in 1980.
Sang-Moon Bae will do his best to prevent that from happening.
Bae, who is looking for his first PGA win, got off to a great start. He birdied the first and second hole to quickly get to 10-under.
With his accuracy off the tee coming and going, Bae was having a hard time staying consistent. However, he dropped just one stroke to the course. That came on the par-three fifth, when he carded a four.
A birdie at No. 8 earned the stroke back, and when he stuck this wonderful approach on No. 13, he moved to 11-under and was right in the thick of the hunt:
Bae closed his round strong, playing the final 13 holes bogey free. If he can hit enough fairways on Sunday, he will have a great shot at victory.
Meanwhile, playing safe and smart golf, Gillis didn't suffer a bogey until the par-three seventeenth, and he quickly picked that stroke back up with a birdie on No. 18.
He has tremendous touch around and on the greens. He has .568 strokes gained-putting over the first three rounds. So, even when he misses the greens, he is a good bet to get a par.
And he got a lot of pars—13 of them to be exact.
Another golfer to watch on Sunday will be Scott Piercy. He fired a four-under 66, and showed he can make a move in a hurry on this course by knocking in six birdies on the day.
This remarkable putt on No. 17 helped him get the final of his birdies.
Piercy will begin the final round three shots off the lead at 10-under, and is one of the many golfers with a strong shot at victory.
All of this sets up for what should be a remarkable final round.
