BLAINE, United States (AFP) – American Scott Piercy caught fire on the back nine en route to a nine-under 62 and a two-shot lead in the first round of the PGA Tour’s 3M Open on Thursday.
Piercy, who hasn’t won in 14 months, finished his bogey-free round with a six-foot birdie putt on the par-five 18th to pull ahead of Canada’s Adam Hadwin and Hideki Matsuyama of Japan.
Hadwin and Matsuyama both shot 64.
Piercy rolled in six birdies over his final eight holes after making the turn at the TPC Twin Cities course in three-under. He also had a 30-foot putt for birdie on the par-four 16th.
Hadwin birdied four straight holes among his final nine. He made two putts from between 20 and 25 feet in his round.
Brian Harman, Im Sung-jae, Patton Kizzire and Sam Saunders are tied for fourth after shooting six-under 65.
South African Dylan Frittelli, and Americans Brendan Steele and Bryson DeChambeau are among a large group who shot five-under 66, four shots back of Piercy.
World Number One Brooks Koepka made five birdies for a four-under 67 that left him five shots adrift. Koepka has won six PGA Tour events of which four are major championships.
Phil Mickelson had seven penalty strokes, including two on the par-five 18th, and finished with a three-over 74.
