FORT WORTH, Texas – Kevin Na regained sole possession of the lead with a late birdie Saturday at Colonial, taking a one-stroke lead over Ian Poulter into the final round.

Na's 1-under 69 in the third round included a couple of bogeys. He is at 11-under 129 at a very damp Hogan's Alley.

Poulter, who shot 68, had dropped out of a share of the lead after starting the back nine with a four-putt double bogey. But he was again tied with Na after making a 32-foot birdie at No. 15, the same hole where his playing partner two-putted from 6 feet after his approach missed the green.

With their balls close to each other on the No. 17 green, Poulter had a 15-foot birdie try that slid by the hole. But Na then made his 14-footer to reclaim the outright lead.
