BETHESDA, Md. (AP) -- There were all sorts of fun things to learn about Anthony Kim after he won the AT&T National. What's with the new flashy belt buckle? And what's the real story behind his decision to attend the University of Oklahoma?

The belt buckle was unmistakable. Already known for wearing garish belt attire adorned with his initials, Kim donned a buckle featuring what appeared to be a diamonds embedded into the letters "AK" as he played Sunday's round at Congressional.

"It weighs a lot. It costs at lot," Kim said. "I'm glad I wore it today. I needed a big day."

Kim said the buckle arrived Wednesday from a clothing company that has him scheduled for a photo shoot on Monday. He wasn't even sure if the sparkling things were diamonds.

"It looks like diamonds, and they are pretty upscale," Kim said. "So I would be very surprised if it isn't."

As for his Oklahoma drill, Kim said he planned to go to a school closer to his California home and accepted a visit to OU just to get tickets to a football game. But the Sooners' atmosphere at kickoff won him over.

"It started pouring rain," Kim said. "And I thought everyone was going to leave because that's what I was used to back home. And everyone decided that they were going to take off their shirts and stay. There were people going wild, and I just loved the atmosphere. That's why I chose OU, because of OU football."
