Golfer Lexi Thompson ended up losing a tournament after a TV viewer reported a violation of the rules, which officials apparently missed. An eagle-eyed viewer reported in an email that the 22-year-old golfer's placement of the ball was wrong. The viewer saw Thompson marking the position of the ball then picking it up. Video shows that when she puts it back, it's an inch closer to the hole. Upon hearing the mistake was going to cost her four strokes, Thompson replied, "Is this a joke?"
