Second-round play at the True South Classic has been suspended due to darkness. Billy Horschel leads in the clubhouse at 13 under, one clear of Matt Bettencourt, who has also finished, and Jason Bohn, who is halfway through his second round. Horschel, whose only previous overnight lead came after two rounds of the 2011 McGadrey Classic, carded a bogey-free 9-under 63 that featured a pair of eagles.  After starting the day in a tie for 24th, he wasted little time making his move with birdies on two of his first three holes en route to a 31 on his opening nine. Bettencourt, whose last five holes Friday featured three birdies, a bogey and an eagle, had the clubhouse lead at 12 under before Hurley passed him. Steven Bowditch (-11) is currently in fourth. Another shot back is 2011 Web.com Tour Player of the Year J.J. Killeen, who is through 12 holes in his second round. Heavy Thursday storms pushed the conclusion of Round 1 into Friday morning at Annandale. Inclement weather delayed play for an hour late Friday morning before the field could complete Round 1. There will be 64 players completing their second rounds on Saturday. Play is scheduled to resume at 7:30 a.m. local time (8:30 a.m. ET).
