PGA Tour pro WDs from Bank of Utah Championship after making 9 on par-4

Denmark's Rasmus Neergaard-Petersen decided to withdraw from the Bank of Utah Championship after making a devastating quintuple bogey. 

Petersen racked up the big score at the par-4 5th, his 15th hole of the day, after he began the PGA Tour event at Black Desert Resort on the 10th. 

Shot tracking showed the 27-year-old hit his first tee shot into the native area and decided to play a provisional. 

He found his first but was forced to take a drop. From there, he took five more shots to hole out. 

Neergaard-Petersen then decided to withdraw from the tournament with his score at 10-over par. 

His scorecard also include one bogey, three double bogeys and two birdies. 

The official PGA Tour communications department confirmed the golfer cited illness as the reason for his withdrawal. 

Bauchou leads by one in the desert

Zach Bauchou fired a career-best 9-under 62 on Thursday to take a one-shot lead after the opening round of the Bank of Utah Championship, as a barrage of low scores set the pace at Black Desert Resort.

Bauchou closed his bogey-free round with birdies on his final two holes, making a 12-foot putt at the par-3 17th before reaching the 602-yard 18th in two shots and two-putting for another birdie. 

The 30-year-old's 62 gave him his first outright 18-hole lead on the PGA Tour.

Eight players were one stroke behind at 8-under 63, including England's Jordan Smith and American Nick Dunlap. 

Smith produced one of the day's highlights when he holed his second shot from 238 yards on the par-5 9th for an albatross, the first of his career.

Dunlap, meanwhile, carded his lowest round in more than two years. 

He hit every fairway and finished without a bogey, rolling in more than 100 feet of putts to move within a shot of the lead.

Canada's Sudarshan Yellamaraju also posted a 63 after recovering from a double bogey early in his round. 

He added two eagles and four consecutive birdies during a strong finish.

A group at 7-under 64 included Canada’s Nick Taylor, South Africa’s Christiaan Bezuidenhout, defending champion Michael Brennan, Garrick Higgo and Rico Hoey. 

Taylor finished with an eagle after holing a 50-foot putt.

Jackson Koivun, fresh from helping the United States win the Presidents Cup, endured a more difficult opening round. 

After three consecutive bogeys left him 2-over, the 21-year-old rallied with four birdies in his final five holes for a 3-under 69.
