Adam Svensson followed up his terrific 10-under opening round in solid fashion, finishing Friday with a five-under 67 to sit at 15 under, two strokes clear of the chasing pack.

After posting two birdies and two eagles on the four par-fives in his first trip around the course, Svensson came back to earth with one birdie and three pars, but a string of three birdies from four holes on his front-nine left him in a strong position.

While he is the leader going into the weekend, it remains to be seen if he will be the 36-hole leader as a lengthy five-hour rain delay wreaked havoc. It meant a number of contenders were forced to head off the course at the end of the day with plenty of holes remaining due to poor lighting.

In outright second place at 13 under is American Trey Mullinax, who had six birdies and seven pars through his first 13 holes on Friday before having to call it a day. He will resume at 8:30am, with a chance to begin the third round right up with Svensson if he can finish the way he started.

There is a seven-man logjam for third place at 12 under, and only three of those players – Mark Hubbard, Robin Roussel and Brandon Hagy – have made it through their full 36 holes.

Tom Lewis still has four holes to play, Jonathan Byrd has five holes to play, Matti Schmid has eight holes remaining and Max McGreevy had only made it through nine.

Hagy and Byrd were the standouts from that group on Friday, with Hagy posting a 10-under 62 for the round of the day, while Byrd had seven birdies across a nine-hole stretch and is yet to record a bogey.

International players Ricardo Gouveia of Portugal, Colombia's Camilo Villegas and Germany's Yannik Paul highlight the group at 11 under tied for 10th place, and they are six strokes clear of the projected cut-line.
