The last time Kevin Na took the lead into the final round of a tournament, he faltered badly.
For Ian Poulter, though he laughs about it, there is that anonymous survey of PGA Tour players done by Sports Illustrated where he and Rickie Fowler tied as the most overrated player on tour.
Na and Poulter both have a chance to change perceptions at Colonial.
With a birdie on the 17th hole Saturday, after the pair played from almost the same spot, Na regained the outright lead for a one-stroke advantage over Poulter going into the final round at a very damp Hogan's Alley.
"When it comes to crunch time, you've got to trust your stroke and just stay in the moment," Na said when asked about a chance for his second PGA Tour victory Sunday.
At The Players Championship three years ago, Na led after 54 holes before closing with a 76.
Na shot a 1-under 69 on Saturday, a round that included a couple of bogeys, to reach 11-under 199. Poulter had a 68.
Charley Hoffman has third at 9 under after a 66. Chris Kirk, a two-time PGA Tour winner last season, had a 65 for the best round of the day and was tied for fourth at 8 under with Brandt Snedeker (66).
Defending champion Adam Scott carded his second consecutive 66 since an opening 72. He was tied for 10th at 6 under in a group that included Jordan Spieth, the 21-year-old Masters champion from Dallas playing the first of consecutive weeks at home in North Texas.
Spieth, the first-round co-leader after a 64, followed his second-round 73 with a 67.
Byeong Hun An shot a 5-under 67 to share the lead with Francesco Molinari after the third round of the BMW PGA Championship in Virginia Water, England.
The South Korean trailed Molinari by a shot after the second round but made seven birdies, including two in the last two holes, to equal the Italian's overall score of 14-under 202 going into the final day.
Molinari, who has led from round one, shot a 68. Thongchai Jaidee of Thailand was two shots back in third after a 68.
