Kevin Na, the man with the stuttering golf swing, ran afoul of the law at the Crowne Plaza Invitational in Friday's second round when his threesome with Johnny Huh and Aaron Baddeley were placed on the clock for slow play. Na objected to the action strenuously. Huh shot a 66 Friday and was at four-under par through 36 holes. Baddeley's 70 left him one-over par going to the weekend. Na made three bogeys after being put on the clock -- Nos. 9, 12 and 14 -- but birdied Nos. 16 and 17 to shoot 71 and also be at one over after 36 holes. Here's what Na had to say after Friday's round at Colonial CC:

"We were in position all day. We were waiting the first few holes. I'm constantly looking where we are in position. Off the sixth tee we were in perfect position, off the seventh tee we were doing fine, we were in perfect position. We struggled a little bit on eighth, the par-3, as a group because we had long shots and long putts coming in and we stand on nine and we get off the tee and they are telling us we are on the clock. I get on nine green and I look down 10 fairway and they are on the green. We have an 11-minute interval and we are in position. After I putted on the hole I called them over and said, 'Look, we're in position, we shouldn't be on the clock.' That's all."

Asked if he thought he was being singled out, Na said: "No comment, no comment."

But he was clearly angry:

BENTON HARBOR, Mich. -- Same guy, same course, different day.

Michael Allen shot a 77 Thursday in the first round of the 73rd Senior PGA Championship. He was 13 strokes better than that Friday, carding a course-record, seven-under 64 to vault into contention on a much calmer day at Harbor Shores.

Allen, 102nd after his six-over opening round, was T-5 at one-under 141 when he got to the clubhouse, three strokes behind leader Roger Chapman, who was early in his second round.

It was the lowest round shot in the Senior PGA since Allen Doyle closed with a 64 to win the event in 1999 at PGA National GC. His turnaround equaled the 13-shot swings by Brad Bryant (80-67) and Bill Loeffler (82-69) from the second to third rounds during the 2010 Senior PGA at Colorado GC.

Allen -- the hottest player on the Champions Tour this season with two victories and four other top-four finishes -- made seven birdies (only one on a par 5), saved par after hitting his approach long on No. 7 and didn't have a bogey.

FORT WORTH, Texas -- Among the elements that make up the complex formula of championship golf is the relationship between the player and his caddie. For years now, Zach Johnson and Damon Green have enjoyed the kind of honesty and mutual respect that leads to winning golf, as it did when Johnson took home the green jacket at the 2007 Masters. Now, that bond has grown stronger as they share the death of Green's father.

On the Sunday evening of the Players, soon after Johnson made a 30-foot birdie putt on No. 18 that was the difference between finishing T-2 or fifth at TPC Sawgrass, Green jumped in his car and drove the 360 miles from Ponte Vedra Beach to Pensacola for one last chat with his father, Rev. Douglas Brooks Green, before he passed away the following Thursday from stomach cancer.

"I got there at 11:30 and we stayed up until about 2 just talking," Green said Thursday at Colonial CC after Johnson shot 64 in the opening round of the Crowne Plaza Invitational. "He got to see the telecast [of the Players] and got to see the hat."

The hat was the one Damon wore at TPC Sawgrass that said: "Love Mom and Dad." Green's mother, Ruth, is 90 years old. "Dad was 88," Green said. "He had 87 good ones."

Just one week after his father passed, Green was back at work. "It was tough," he said, "but I thought it would be a lot tougher with everyone coming up and offering their condolences. But I am at ease as much as possible with it because I know he is in a better spot. I know he's up there. He was in pain the last few days."

Eleven years ago, Sergio Garcia confirmed his status as a rising star, capturing his first win at Colonial less than two years after nearly taking down Tiger Woods at the 1999 PGA Championship. Remember "El Nino"? That affable, fiery Spanish bundle of energy? I do -- and I miss him.

I remember trying to model my own game after Garcia's soon after that epic duel at Medinah. And why not? Garcia was a fearless kid who hit his own stinging irons and who always seemed to be having fun on the course. Now he looks like a guy who makes playing golf for a lot of money on exquisite courses around the world not much fun at all.

He's No. 22 in golf's world ranking, but Garcia is still trying to live up to his promise -- and it doesn't look promising that he will. As the man with a Ben Hogan-like swing returns to Hogan's home event more than a decade later, the only charge he's leading is that of the naysayers who don't think he has what it takes to win one of golf's biggest events.

"I've been trying for 13 years, and I don't feel capable of winning (a major)," Garcia was quoted by Spanish-language media following a third-round 75 at the Masters that dropped him out of contention. "I don't know what happened to me. Maybe it's something psychological."

FORT WORTH, Texas -- The first time I covered the Crowne Plaza Invitational at Colonial was in 1997 when it was known as the MasterCard Colonial, the best player in the world was Tiger Woods and I was the golf writer for The Associated Press. A lot has changed since then. For Tiger, the Colonial and me.

The story that week was that it would be the first time Woods and Fuzzy Zoeller crossed paths since Fuzzy made racially insensitive remarks following Tiger's 12-stroke victory in the Masters at the age of 21. Woods took a month off after that historic victory, then won the HP Byron Nelson, in which Zoeller didn't play, setting up Colonial.

"He's doing quite well, pretty impressive," Zoeller, known for his irreverent sense of humor, said Sunday evening after Woods' record-setting win at Augusta National. "That little boy is driving well and he's putting well," Fuzzy continued in remarks that aired several days later in a CNN report by the late Jim Huber.

"He's doing everything it takes to win," Zoeller said. "So, you know what you guys do when he gets in here? You pat him on the back and say congratulations and enjoy it and tell him not to serve fried chicken next year. Got it." Zoeller started to leave, then turned around and added: "Or collard greens or whatever the hell they serve."

Jason Dufner's walk-off birdie on the 72nd hole at the HP Byron Nelson Championship rightfully received the most attention of any golf shot hit over the weekend. But what about a grandstand birdie on a tournament's final hole?

That's exactly what Nick Flanagan pulled off at the Nationwide Tour's BMW Charity Pro-Am. Trailing by a shot on the final hole, the 2003 U.S. Amateur champ blew his approach over the green and, well, you have to see what happened to believe it:

Following this stroke of luck, Flanagan converted the birdie and wound up winning in a playoff for his fourth career Nationwide Tour title. After winning the developmental tour's player of the year award in 2007, Flanagan was unable to stick on the PGA Tour, finishing 169th on the money list.

His big break, though, will go a long way towards him getting back to the big leagues. Despite this being just his second Nationwide event of 2012, the win propelled him to 11th on the money list that guarantees a PGA Tour card for the following season with a top-25 finish.

If beating Ernie Els in a playoff to get his first PGA Tour win didn't elicit much of a celebration, it shouldn't be too surprising that Jason Dufner didn't exactly start doing cartwheels on the green after draining a 25-footer for the win on Sunday.

Dufner's dramatic birdie gave him a one-shot victory over Dicky Pride at the HP Byron Nelson Championship. It also led to one of the least-excited reactions you'll ever see for a walk-off putt. Check out the final-round highlights.

After waiting until after he turned 35 to collect his first tour win, Dufner now has two in the past month. Who knows, he might have won at Quail Hollow too -- if he didn't have to get married that week.

And how about Dicky Pride? Dufner's closing birdie kept him from a second career PGA Tour title as well, but considering that first win came in 1994 and he hasn't been fully exempt on tour since 2007, a solo second and a check for $702,000 must have seemed like a win. Judging by his reaction to his finish -- which guarantees him full status on tour -- it did.

From the May 21 issue of Golf World:

Rhein Gibson is 1,444th on the World Ranking, having missed three cuts and finished T-58 in two Nationwide Tour events and two Australian Tour events in 2010 and 2011. But when it comes to playing River Oaks GC in Edmond, Oklah., he's all-world.

Gibson set the course record of 60 earlier this month, then shattered that mark with a 16-under 55 on May 12 at the 6,850-yard venue. The 26-year-old Lismore, Australia, native is a 2008 graduate of Oklahoma Christian, where he was a NAIA All-American. He made 12 birdies, two eagles and four pars during his stellar round.

Gibson's round is believed to be one of the lowest recorded on a full-length (more than 6,000 yards) course. The only 55 recorded in tournament play was by Homero Blancas in the 1962 Premier Invitational in Longview, Texas.

On a Mother's Day when just about everyone associated with the Players -- from tour pros to volunteers -- wore pink to celebrate Breast Cancer Awareness Day, the closest Tiger Woods came to honoring the cause was the colorful energy drink he occasionally pulled from his golf bag. Apparently, Woods is in his own world when it comes to discussing his golf game as well.

Following a final-round 73 that included a dismal front-nine 40, he offered this stunning assessment:

"Just one of those things where Joe (LaCava) and I were talking about that on the front nine, I didn't really hit any bad shots, and all of a sudden, I had a bogey, a birdie and a double," Woods said.

LaCava is Woods' caddie. He also just might be the world's most patient listener. Then again, he is getting paid a lot more than most psychiatrists.

No bad shots? Did we hear that right? How about the sand wedge over the green on No. 1? How about the 9-iron from the middle of the fairway into the water on No. 4? How about the drive on the par-4 fifth? Or your tee shot on the par-3 eighth, both of which could barely be tracked on the computer screen by the PGA Tour's ShotTracker?

A year after one of the toughest losses of his life, David Toms hoped returning to TPC Sawgrass would help jump start his 2012 season and it did. It just took 59 holes to get going.

At one-over par through five holes of his final round at the Players, Toms holed a wedge for eagle from 123 yards on the par-4 sixth. A couple hours later, he'd made the biggest move up the leader board on Sunday, closing with a 65 to jump into the top five at the time of signing his card.

"I was so far back, and I was just trying to have a decent finish," Toms said. "So, you know, no reason why I shouldn't shoot at a flag. What's the difference in 44th and 34th? That's the way I was playing out there, and I just happened to play a great round of golf."
