May 23 (Reuters) - Kevin Na sank a 14-foot birdie putt on his penultimate hole to break clear of a tie at the top with Ian Poulter and edge a stroke in front after the third round of the Crowne Plaza Invitational on Saturday in Fort Worth, Texas.
American Na, who had been two ahead overnight in pursuit of a second PGA Tour victory, fired a one-under-par 69 in overcast conditions at rain-softened Colonial Country Club to post an 11-under total of 199.
Englishman Poulter, seeking his third win on the U.S. circuit, missed a birdie attempt from seven feet at the par-four last and had to settle for second place after returning a 68.
