Taylor Pendrith and Theo Humphrey both shot 9-under, 62 following the first round of the Windsor Championship at Ambassador Golf Club.
The pair are positioned at the top of the leaderboard with a one-stroke lead over Carter Jenkins.
Pendrith was the first to sign for the new Ambassador Golf Club course record after knocking in an 8-foot birdie putt on his last hole of the day, to complete the nine-hole stretch in 29 shots.
Meanwhile, Theo Humphrey, who was recently ranked eighth on the World Amateur Golf Rankings before turning professional last month, played consistent golf all day en-route to his 62.
Leaping out of the gate with a first hole birdie, Humphrey made eagle on the 3rd and made two more birdies before making the turn.
On the back, Humphrey birdied four of his last five to sign for matching front and back 31s.
Behind the two leaders is Raleigh, North Carolina’s Carter Jenkins.
The 22-year-old carded 8 birdies and trails the leaders by one after his first-round 63.
Local golfers David Byrne and Thomas DeMarco were unable due to finish their rounds because of weather.
Byrne was one under and DeMarco at even par.
