Carson Johnson of Signal Mountain, Tenn., embraced the cold and windy conditions to shoot a bogey-free 5-under 66 for the first-round lead in the St. Augustine Amateur golf tournament.

The temperature was in the high 40s and winds gusting to 15-20 mph under cloudy skies early Friday made for a start full of wool caps, multiple layers of clothing and fast and firm greens. Only four players broke par and 22 shot 80 or above in the 76-player starting field on a trying day, especially with tee times scheduled through mid-morning.

Johnson’s bogey-free round included birdies on the par-5 fourth in shooting 34 on the front nine and birdies on No. 10, 15, 16, and 17 to come into the clubhouse at 32. Johnson holds a one-stroke lead over Danny Erickson of Ponte Vedra Beach, Fla.,, a redshirt freshman at North Florida who had five birdies and one bogey in his 4-under 67.

Jason Duff of Elkton, Fla., a University of North Florida senior who grew up in a house right off the St. Johns Golf Club’s first fairway, made birdies on two of the last four holes to shoot 2-under 69.
