GREENSBORO, N.C. (AP) - Byeong Hun An and Sungjae Im each shot 8-under 62 on Thursday to share the lead after one round at the Wyndham Championship.

Mackenzie Hughes, Rory Sabbatini, Patrick Rodgers and Johnson Wagner were a stroke back behind the South Korean leaders in the final PGA Tour event before the FedEx Cup playoffs.

Former Wyndham winners Brandt Snedeker and Webb Simpson joined Jordan Spieth among the nine players at 64.

Both co-leaders shot the best rounds of their PGA Tour careers. An, a 27-year-old South Korean seeking his first career victory on tour, closed with birdies on four of his final six holes and a sand save on the par-4 18th.
