Argentina's Emiliano Grillo posted eight birdies as he finished a curtailed first day of the Indian Open in the lead.
The 25-year-old carded a course-record equalling seven-under-par 65 before darkness fell which meant 24 players could not finish their opening rounds.
Grillo leads by two strokes from Spaniard Pablo Larrazabal, Italian Matteo Manassero and American Paul Peterson.
Frenchman Adrien Saddier was five-under with one hole to play, alongside South Africa's Keith Horne who had played 16 holes.
Manassero made the turn in 36 but then enjoyed an excellent run during which he briefly moved into a share of the lead.
Grillo said after his excellent round: "You have no idea how difficult the course is. I had to play almost perfect golf to shoot a seven-under. I think anywhere else it would have been close to a 59 or something. It was definitely a magnificent round of golf.
"I’m very happy with the way I handled myself out there. It was very tough and I was able to make some good putts and hit the fairways when I needed to."
Grillo is 1000/1 to win the Indian Open outright, while Manassero can be backed at 4000/1 and Larrazabal at 500/1.
