REUTERS: Matthew Wolff shot the best round of his young career on the PGA Tour on Saturday, firing a nine-under-par 62 to move into a share of the lead with Collin Morikawa and Bryson DeChambeau at the inaugural 3M Open.
The 20-year-old Wolff mixed 10 birdies with a bogey in just his fourth start on the PGA Tour to sit atop the leaderboard alongside his compatriots at 15-under after three rounds at the TPC Twin Cities course in Minnesota.
Wolff, who won this year's U.S. college championship, said playing freely was the key to his success so far at the tournament.
"The last couple weeks I felt like I was being a little too strategic," he said after tying the course record also matched by DeChambeau in the second round.
"In college I just kind of let it rip so when I came out here I told my caddie that's what we're going to do this week," he said.
"We're just going to send it and it has been working out."
Wolff was on 59 watch after sinking his seventh birdie of the day on the par-four 10th but failed to convert a makeable birdie putt at 16 and followed that up with a bogey on 17 to put the milestone out of reach.
Fellow Californian young gun Morikawa fired a seven-under 64 in his sixth start on Tour and has shown poise beyond his 22 years through three solid rounds.
"My game throughout my entire life of playing golf has been staying really steady and sticking to my game plan," he said.
"I have a smooth tempo. If I can stay like that tomorrow it should be pretty exciting."
Overnight leader DeChambeau cooled off after Friday's 62, making just two birdies and his first bogey of the tournament on 13 for a round of one-under.
DeChambeau's birdie at the 18th hole moved him into a share of the lead and give the five-time PGA Tour event winner some momentum heading into the final round after an otherwise lacklustre performance.
None of the three leaders can afford to relax with American Wyndham Clark, who shot a seven-under 64 on Saturday, and Canadian Adam Hadwin both a one stroke behind.
