They buried the hatchet, and thankfully not in each other's heads.

Sergio Garcia and Anthony Kim had some history when they arrived at the first tee in the PGA Championship’s Gossip Girl pairing of the Garcia, Kim and pretty boy Camilo Villegas.

Back in February at Riviera, Garcia was playing in the group ahead of Kim during a practice round for the Northern Trust Open. When Garcia was lining up a practice putt on 18, a ball came flying out of the sky. It was Kim’s approach to 18. The Orange County Register had all the details.

Garcia was lining up a putt on the 18th hole, Riviera's famed uphill par-4 finishing hole, when another golf ball dropped out of the sky a few feet from him.

Startled, Garcia spun around and spotted Kim in the 18th fairway, looking guilty.

"Sergio was really ticked off," recalled Kiki Garcia (no relation), head professional at General Old Golf Course in Riverside, who was in the greenside gallery when the incident occurred. "I (jokingly) told him I had his back. But Sergio said, 'I don't need your help. I'll break every club I have over his head.'"

Kim later apologized, according to the Register, and if there was any bad blood lingering, it’s been cleared up.

“Anthony is a great guy,” Sergio said Thursday. “Obviously I'm good friends with Camilo. It was very enjoyable. I think this is the first round I played tournament round with Anthony, and it's very impressive.”

Kim responded in kind, suggesting that the whole pairing was one big circle of friendship.

“Sergio and I are friends and Camilo and I are friends and obviously Camilo and Sergio are friends,” Kim said. “It was a good time. It was pretty relaxed and we just tried to play some good golf.”

Still, I’d watch these two closely if they face off in the Ryder Cup.
