NICHOLASVILLE, Ky. — Lucas Glover continued the hot streak that began when he switched to a long putter, shooting a 9-under 63 on Thursday for a one-shot lead in the Barbasol Championship.

The 43-year-old Glover extended his streak of rounds in the 60s to nine. After struggling with his putting for years, the 2009 U.S. Open champion began using the broomstick two weeks ago at the Rocket Mortgage Classic and finished tied for fourth. He followed that with a tie for sixth last week at the John Deere Classic.

Fellow PGA Tour veterans Ryan Moore and Ryan Armour each shot 64 at Keene Trace Club.

Glover made six birdies on the front nine to turn in 5-under 31. Then he holed his approach from 138 yards for eagle on the par-4 12th and made consecutive birdies on the 15th and 16th holes.

Glover won the last of his four PGA Tour titles at the John Deere two years ago.

Armour, one of the first players to go off Thursday morning, and Moore were nearly as impressive on a sunny, humid day.

Armour birdied Nos. 2-5 and closed with another run of four straight birdies. Moore birdied each of the four par-5s in his bogey-free round.

Daniel Brown, Wesley Bryan, Cody Gribble and Andrew Novak each shot 65.

The group two shots off the lead included four European tour players who traveled across the Atlantic for this co-sanctioned event: Marcus Helligkilde of Denmark, Marcus Kinhult of Sweden, Angel Hildago Portillo of Spain and American Johannes Veerman. They were joined by Americans Adam Long and Bo Van Pelt and Swede Vincent Norrman, who plays on the PGA Tour.
