Sung Kang shot a 1-under 71 to hold a three-shot lead over Rickie Fowler after the third round of the Houston Open on Saturday.
After shooting a tournament course record 9-under 63 on Friday, Kang took a commanding six-shot lead with a 36-hole tournament record of 129 through two rounds.
However, on Saturday, it was Fowler's day to chase history, shooting a 5-under 67 to trim Kang's lead as they head into the final round.
After Thursday's 8-under 64, Fowler held a one-shot lead over Kang after the first round, but slipped to fourth on Friday with a 71. He returned to form on Saturday and has a PGA Tour career-best 22 birdies through three rounds.
Behind Kang and Fowler at 17-under 199 and 14-under 202 through three rounds, respectively, Russell Henley is 13-under 203 and Luke List is 12-under 204. No one else is within eight shots of Kang.
