In the third round of the HSBC, Anthony Kim hit his ball into a hazard (I believe it was a lateral hazard.) The ball was several feet into the hazard, which was thick vegetation, but Kim elected to play it. He took a hard swing but the ball didn't come out.

While everyone was looking for the ball, the announcers started discussing Kim's options and one announcer mentioned a "lost ball" and the other announcer corrected him and said "no, you can't lose a ball in a hazard" and the first announcer quickly said "oh, that's right, you can't have a lost ball in a hazard."

I've never heard that. I scanned the USGA Rules, but couldn't find an explanation. Can anyone enlighten me?
