Kevin Roy fired a 10-under-par 62, the lowest round of his career, to capture the first-round lead at the Puerto Rico Open on Thursday at Grand Reserve Golf Club in Rio Grande.

Roy holds just a one-stroke advantage over Chris Gotterup, who stood at 10 under himself before his only bogey of the day came at the par-4 18th. Davis Riley and Denmark's Rasmus Neergaard-Petersen were tied at 8-under 64, and Karl Vilips of Australia was alone in fifth at 7-under 65.

Due to a weather delay of one hour and 17 minutes in the early afternoon, 24 players were still on the course when play was suspended due to darkness, none of them lower than 6 under. They will complete their first rounds early Friday.
