This is a truly bizarre story...
Lexi Thompson was in the lead by 3 strokes going into the final round during a major tournament on the LPGA Tour over the weekend .
An LPGA official then told her she was going to be penalized 4 strokes which would take her out of the lead.
Here's what happened...
When the tournament was being televised on the Golf Channel on Saturday, a viewer noticed she improperly marked her ball on the green.
She didn't just mark it, she actually changed it enough so that it altered the position of the ball.
The viewer saw this and reported it by emailing the LPGA. When they looked back at the video of the telecast, they saw she improperly moved it a little too far and she was penalized.
Wow, I've never heard of anything like this before.
