GREENSBORO, N.C. (AP) - Byeong Hun An shot a 4-under 66 on Saturday for a one-stroke lead after three rounds at the Wyndham Championship.
An was at 17-under 193 entering the final round of the PGA Tour's final event before the playoffs.
Former Wyndham winner Webb Simpson and Brice Garnett were tied for second, with Simpson shooting a 65 and Garnett a 66. Ryan Armour was 15 under following a 65.
An has held or shared the lead after each of the first three rounds, and has yet to play a hole worse than par. The 27-year-old South Korean with three international victories has put himself in position to claim his first win on tour.
