Glover closed with a seven-under 64 to finish at 19-under and win for the fourth time in his career, the most recent in 2011 at Quail Hollow.

He was among two dozen players separated by three shots on the rain-softened TPC Deere Run in Silvis, Illinois when he went on a tear.

It started with a 15-foot birdie putt on the par-3 12th hole. He hit his approach into four feet and seven feet on the next two holes, and then flushed a 7-iron to three feet on the 15th hole to take the lead.

Glover finished his run with a 12-foot birdie on the par-5 17th, and a six-foot putt to save par from the bunker on the 18th that he figured would come in handy.

It never got to that. No one could catch him.

Glover kept it simple, with his game and his observations, saying he "ironed" it well and made a bunch of putts.

"They went in and I kept the pedal down," Glover said. "There's a lot of birdies out there, a lot of great players coming in."

"It's been a long 10 years. There's been some struggles. I never lost sight of believing I could do this and win again. It's always nice to prove yourself right." – Lucas Glover

Fellow Americans Ryan Moore (68) and Kevin Na(68) tied for second, a shot clear of Adam Schenk (67), Luke List (68), Scott Brown 69) and Colombia's Sebastian Munoz (71).

Cameron Percy finished as the leading Australian after charging home with a 65 to be tied 11th.

The victory at the 50th edition of the John Deere Classic sends Glover back to the Masters, the US PGA Championship and allows him to start next year on Maui for the Tournament of Champions, a place he hasn't been in a decade.

"It's been a long 10 years. There's been some struggles," Glover said. "I knew it was in there. I had to clean up my brain a little bit and just hit some shots, just play golf. I never lost sight of believing I could do this and win again. It's always nice to prove yourself right."

Glover already was in the Open Championship from having reached the Tour Championship in 2019 (the 2020 Open was canceled by the pandemic). Moore earned the lone spot at Royal St. George's, though it was unclear he was going to take it.
