Na in the Lead, and Trying to Keep Pace PONTE VEDRA BEACH, Fla. - Is it time for Kevin Na to win his second PGA Tour event? For most of his back nine Saturday at the Players Championship, time did not appear to be on Na's side. Paired with Zach Johnson, Na was put on the clock on the eighth hole. He was given a bad time on the 16th hole, which he unsuccessfully appealed. Na claimed he exceeded the allotted time because his caddie's shadow was in the way. If he had been slapped with a second bad time before the end of the round, he would have received a one-stroke penalty. Mark Russell, the PGA Tour vice president for rules, competition and administration, said Na, who carded a bogey-free, four-under-par 68 to take a one-stroke lead over Matt Kuchar, was not on the clock for the final two holes. "We took him off the clock at the 17 tee because he was back in position," Russell said. The twosome ahead of Na and Johnson - Harris English and Kuchar - also were put on the clock on the back nine. At that point, Na said, "I knew it was going to be tough to keep up with them because they're going to start taking off." Na, who has not been able to settle into a new setup that he implemented a year ago, takes a waggle and a half waggle, over and over, until he feels comfortable making a full swing. It's a tic that's not restricted to competition. "Yeah, I whiff it in practice rounds, I back off," Na said. It's the same thing; I do it on the range, too. The difference, of course, is that in competition Na's internal struggles are there for an audience to see - and belittle. "I get ripped a lot," Na said. I know TV, Twitters and fans are tired of me backing off. But you know, I'm - I understand people being frustrated with me backing off, but all I can tell you guys is honestly, I'm trying, and it's hard for me, too. He added: "It's tough, especially when you're on the clock and you have to hit within 40 seconds - if you're first, it's a minute. So there's added pressure. And only the whole world is watching, so there's a lot more pressure there, too. It's hard, but you know, I'm swinging it well, so if I trust it and pull the trigger, my ball is kind of going where I'm looking, which is great, and also I'm rolling the ball great.
