SEA ISLAND - Chris Kirk fired a second-round 66 to seize a one-shot lead in the US PGA Tour McGladrey Classic, where darkness halted play Friday 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 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 -- and a chip-in from 60-feet at 14. 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.–AFP
