What is the record for the fewest putts needed in one 18-hole round of a PGA Tour tournament?

More about the the PGA Tour record for fewest putts in a round

The record is currently shared by nine golfers: Sam Trahan, Mike McGee, Kenny Knox, Andy North, Jim McGovern, Corey Pavin, Ken Duke, Blake Adams and Cameron Smith.

Most recently, in August 2021, Cameron Smith tied the PGA TOUR record for fewest putts during his second-round 62 at the World Golf Championships FedEx St. Jude Invitational.

Cameron Smith had 16 putts through 17 holes. 2 putts to tie and 1 putt for a new record. If he had one putted the 18th green, he would have held the PGA TOUR record for the fewest putts on his own.
