Okay, I know Tiger's win at the U.S. Open at Pebble Beach was a few years ago but I just read an article the other day in a golf magazine about how he almost "lost" the tournament. Yes, I know, he ended up winning by 15 strokes.
Anyway, it happened on Saturday morning finishing the delayed 2nd round. Tiger hooked his drive into the ocean on 18 and asked Steve Williams for another ball. Steve recommended that Tiger hit a 2 iron but Tiger insisted on hitting driver. Anyway, this is important because Steve found out it was Tiger's last ball when he reached into the bag. Apparently, Tiger had practiced putting in his room the night before and the next day, they only took 2 balls out with them. Anyway, the magazine article I read stated he would have been DQed had he lost his 2nd ball but I just found this article that states it wouldn't have been the case.
