BLAINE, Minnesota (AP) -- Scott Piercy went on a late birdie binge en route to a 9-under 62 and the first-round lead at the inaugural 3M Open on Thursday.
Adam Hadwin and Hideki Matsuyama are each two shots back after a 7-under 64 at the TPC Twin Cities.
Seeking his fifth career tour win and first since the 2018 Zurich Classic, Piercy birdied one of his first seven holes and eight of his final 11, including a nearly 30-foot putt on No. 16 to get to 8 under.
Brian Harman, Sungjae Im, Patton Kizzire and Sam Saunders are among a group three back after shooting 6-under 65.
Bryson DeChambeau is among nine players who shot 5-under 66 and are four shots back.
Brooks Koepka, the world's top-ranked player, is among more than a dozen players that shot a 4-under 67. Nate Lashley, who won last week's Rocket Mortgage Classic in Detroit, finished 2 under.
The 3M Open is the first regular tour event in Minnesota since 1969; however, the U.S. Open and PGA Championship have each twice been contested at Hazeltine National Golf Club. The 2016 Ryder Cup was also played there and is to return in 2028.
