Chris Kirk fired a second-round 66 to seize a one-shot lead in the US PGA Tour’s McGladrey Classic, where darkness halted play for a second straight day.

Kirk’s eight-under par total of 132 put him one ahead of 2012 US Open champion Webb Simpson, fellow Americans Briny Baird and Kevin Chappell and Australian John Senden.

Kirk played in the worst of the windy conditions on Friday but managed to nab five birdies on the back nine, which included a 40-foot putt from off the green at the 11th – his second hole of the day.

Senden’s day was highlighted by an eagle at the par-five 15th, and he finished the final hole of his second-round 67 in near darkness to join the group on 133. Play was then halted.

Chappell had an eagle and four birdies to offset two bogeys and a double-bogey at the par-three third in his two-under 68.

Baird, meanwhile, had four birdies and four bogeys in his even par 70, while Simpson kept mistakes to a minimum despite the blustery conditions, scoring just one bogey along with three birdies in his 68.

The tournament fell behind schedule on Thursday, with a two-hour fog delay in the morning.

George McNeill returned on Friday morning to finish a first-round 62 that gave him the lead, but he ballooned to a 76 in a second round that included a run of five straight bogeys.

His was not the only score that soared, and Chappell counted himself lucky to get his two-under effort in early.

“You hit some not-so-perfect shots and get some bad breaks with the wind gusting and you get exposed really quickly,” Chappell said.

“I was fortunate to come to that realisation that there’s some luck involved today and that maybe for a period of time I was one of the luckier guys out here.”
