Matthew Wolff made a 26-foot putt from the fringe for an eagle on the final hole to win the 3M Open at 21-under par on Sunday, beating fellow rookie Collin Morikawa and Bryson DeChambeau by one stroke in a tense finish to the first-time PGA Tour event. The 20-year-old Wolff struck his second shot on the par-5, 573-yard hole from the fairway to the far left of the green and just a few feet away from a bunker. He sank the dramatic putt in front of a packed 18th gallery at the TPC Twin Cities, before watching Morikawa just miss his eagle attempt from 22 feet. As the ball rolled about 3 feet too long, Morikawa winced as Wolff hugged his caddie in celebration of the $1.152 million prize. DeChambeau, playing directly in front of the Morikawa-Wolff pair, had just finished his up-and-down afternoon with an eagle to take the short-lived lead.
