On Saturday at the BMW Championship, Justin Rose was simply trying to post a score to help him move up the leaderboard, a goal for anyone well back of the leaders headed into moving day.
The 2013 U.S. Open champion was 3-under heading into the par-5 14th hole, and that's when some wacky stuff happened.
Rose was preparing for an approach shot, hoping to add another birdie and really make a move at Conway Farms, but his practice swing divot ended up hitting his golf ball, moving it and forcing Rose to take a penalty for his ball moving out of the original spot.
Rose ended up making bogey on the hole, posting a third round 69 to sit well back of the leaders after 54 holes.
Golf has plenty of strange penalties, but this one can really frustrate you if it happens.
