Aussie Marc Leishman shot a second successive round of four-under par to remain in contention at the halfway mark of the Nationwide Tour Championship in Texas. One bogey and five birdies took the Australian to eight-under overall and a tie for fourth position, three shots behind leaders Darron Stiles and Gerrett Osborn. American Colt Knost is two shots behind the joint leaders at nine-under par. A bogey on the last hole condemned Gavin Coles to a two-under par 69, but the Aussie is still well placed in a tie for 13th at five-under overall.
