Billy Horschel carded a 9-under 63  Friday to take the clubhouse lead at the True South Classic. Horschel birdied his final hole to move one shot ahead of Matt Bettencourt, who had the lead all to himself at 12 under before Horschel's late rally. Horschel, who started his second round on No. 10, rolled home a five-foot eagle putt on the par-5 18th to make the turn at 5 under for the round. He added a birdie on the fourth before converting a 10-foot eagle try on No. 5 to catch Bettencourt at 12 under. After making pars on holes 6-8, Horschel stuck his 147-yard approach shot inside five feet on the par-4 9th hole and dropped his fifth birdie of the round to go along with his pair of eagles. The 25-year-old Floridian appeared to be turning the corner late last season when he earned his first two top-10 finishes on the PGA TOUR. Horschel has just one top-25 finish in 10 starts on TOUR this year but has made 80 percent of his cuts. Click here to replay Horschel's second round.
