Lee finishes strong but can't catch Highsmith

Highsmith rallied from a four-shot deficit on Sunday with three straight birdies around the turn and a 20-foot birdie putt on the par-3 17th that all but clinched it, giving him another six-under 64 to win his first PGA Tour title by two shots.

"Winning was the last thing on my mind," Highsmith said.

"It's incredible to come out on top. I played probably the best round of my life."

Lee finished in a tie for 11th at 13 under, while fellow Aussie Karl Vilips (72) was joint-39th, a further four shots adrift.

Highsmith had a little help from Jake Knapp, who opened the tournament with a 59 and held it together until one shot into the water and two more to get out.

Knapp, trying to become the first wire-to-wire winner in tournament history, had a one-shot lead when his wedge to the 11th came up short and into the water, with only half of the golf ball submerged. He tried to blast out and it trickled down the slope and back to the water. He tried again, this time the ball holding up in the rough.

"Didn't hit any of them really hard enough, unfortunately," Knapp said.

He would up with a triple bogey and never caught up. Knapp (72) tied for sixth along with Michael Kim (71), who played with him in the final group.

Jacob Bridgeman (64) and J.J. Spaun (66) shared second place.

Highsmith, a 24-year-old lefty with a bucket hat and a broad smile, became the first player to make the cut on the number and win since Brandt Snedeker at Torrey Pines in 2016.

With so many players in the mix going into the final round, it was set up to be a wild finish, and five players had at least a share of the lead at one point.

Highsmith eliminated the drama in the final hour with a flawless round and an unforgettable weekend he played in 14-under 128. His big run started with a wedge to three feet on No.9. He two-putted for birdie on the par-5 10th and rolled in an 18-foot birdie on No.11.

He added a 15-foot birdie putt at the 13th to take control, and then sealed it with his birdie putt down the slope on the 17th.

Highsmith is the second first-time winner in as many weeks, following Brian Campbell winning the Mexico Open. He finished at 19-under 265 and picked up plenty of perks. Along with earning a place in the Masters and PGA Championship, Highsmith is in the remaining five signature events, starting next week at Bay Hill.

Highsmith shot the lowest 72-hole score since the tournament moved to PGA National, which has held two PGA Championships and a Ryder Cup, in 2007.
