France's Antoine Rozner made a stunning start to the defence of his title in the AfrAsia Bank Mauritius Open.
Rozner fired an eagle and 10 birdies in an opening 62 to set the course record at La Reserve Golf Links, which is staging a DP World Tour event for the first time.
Rozner, whose victory last year came at Mont Choisy Le Golf, started from the 10th and made five birdies in his first seven holes before an eagle on the 18th took him to the turn in just 29 shots.
An historic 59 was a distinct possibility when Rozner started the back nine with four birdies in the first five holes, but he pulled his tee shot on the sixth into the water and also bogeyed the ninth following a birdie on the eighth.
"I couldn't dream of a better start," the world number 128 said.
"I started really hot, shooting seven under on the back nine. It was unbelievable, I didn't miss a single shot, holed everything I had and holed a bunker shot on 18.
"Everything went my way and then I just kept going for the birdies on one, two and three. After the birdie on number five I really thought about shooting 59 but unfortunately for me the bad tee shot on six cost me that magic number.
"But I'm really happy with my round, amazing score and 10 under is my lowest score ever."
Despite such a low score, Rozner only ended the day with a one-shot lead over England's Paul Waring, who birdied five of his last nine holes to return a bogey-free 63.
South Africa's Jayden Schaper was two shots further back after making an eagle and seven birdies in his 65, with course co-designer Louis Oosthuizen - who won the Alfred Dunhill Championship on Monday - returning a 68.
