Brian Stuard shot an 8-under 64 on Thursday to top the leaderboard in the suspended first round of the Zurich Classic at Avondale, La.
The 33-year-old Stuard had only 21 putts in his bogey-free round at TPC Louisiana, finishing his final hole after a rain delay of nearly five hours.
"It was just one of those days where it seemed like I was really reading the putts well, and luckily they were going in," Stuard said. "I picked this putter up last week in San Antonio and had a good feel for it. I putted well last week and it continued over to today."
None of the afternoon starters were able to finish before darkness suspended play.
