Adam Hadwin and Ryan Armour have waited a long time for their second PGA Tour wins, and they will enter the weekend with a chance as they sit atop the leaderboard at the 3M Open. 

The Canadian Hadwin and the American Armour each followed opening-round 67s at TPC Twin Cities with six-under-par 65s Friday to sit at 10-under for the tournament as first-round co-leader Rickie Fowler crashed out of the top spot after shooting 73.  

The 45-year-old Armour birdied four of the last eight holes with a bogey mixed in at 13 to claim a share of the lead.

Hadwin, 33, started on the back nine and had a roller-coaster ride through the same stretch of course, taking a bogey at 13 and double bogey at 15 with birdies on 14 and 16 before settling in for a more consistent final nine holes. 

Armour's lone Tour win came at the Sanderson Farms Championship in October 2017, while Hadwin secured his only title to date seven months earlier at the Valspar Championship. 

Fowler entered the day tied with Troy Merritt and Jhonattan Vegas after carding a bogey-free 64 Thursday for his best score of the year, but he managed only one birdie Friday and finished his round tied for 26th at five under overall. 

Merritt also dropped off the pace with a 71, leaving him three back of the leaders, while the Venezuelan Vegas (69) is one stroke back along with Bo Hoag, Chez Reavie and Roger Sloan. 

Louis Oosthuizen is four back of the lead after a second consecutive 68, while former world number one Luke Donald (68) is five back at five under. 

Former Masters champions Sergio Garcia (70), Patrick Reed (70) and Bubba Watson (68) just made the two-under cut.

Among the high-profile players missing the cut were Dustin Johnson (72) and Stewart Cink (73), who were both at even par for the tournament. 

Dylan Frittelli (76) also did not make it to the weekend on the heels of his fifth-place finish at The Open.
