ST. SIMONS ISLAND, Ga. -- Billy Horschel charged to the clubhouse, going 4 under on his final three holes Friday, to reach 12 under and take a two-shot lead after 36 holes of the McGladrey Classic. Horschel was two shots off the pace set by Webb Simpson and Michael Thompson after a bogey on the par-4 13th, but he eagled No. 15 before posting birdies on Nos. 16 and 18 to complete a second-consecutive 6-under 64 and take the lead into the weekend at Sea Island.
