Sam Burns earned his maiden PGA Tour title after winning the Valspar Championship by three strokes.

Burns and 2011 US PGA Championship winner Keegan Bradley had been level atop the leaderboard through the second and third rounds in Palm Harbor, Florida.

But Burns broke the deadlock with his fellow American on Sunday courtesy of a three-under-par 68 at Innisbrook Resort and Golf Club.

Burns mixed six birdies with three bogeys in the final round as the 24-year-old improved to 17 under and became the second youngest winner in Valspar Championship history.

He also became the fifth player to claim his first Tour title at the tournament, with Adam Hadwin the last to do so in 2017.

An even-par 71 saw Bradley drop down into sole possession of second spot – the four-time Tour champion's seventh runner-up finish in 273 starts.

It all turned sour for Bradley on the back nine, where he found water on the par-three 13th hole, leading to a double bogey. Burns birdied the 14th to open up a three-shot advantage and never looked back.

Viktor Hovland (65) and Cameron Tringale (68) finished tied for third – four strokes behind Burns, while American star Justin Thomas (70) earned a share of 13th position, six shots further back.

Two-time defending champion after the 2020 event was cancelled due to the coronavirus pandemic, Paul Casey's bid for a three-peat ended following his final-round 68, which left him tied for 21st.

World number one Dustin Johnson, meanwhile, closed out the tournament 15 strokes adrift after his two-under-par 69.
