Charley Hoffman had been in control of the 81st Masters for most of the week, the table set by his amazing 7-under 65 which was the best score of the blustery first round by four shots.
That all changed on the par-3 16th hole in Saturday's third round. He led by a shot at 6 under when he reached the tee.
When he walked off, Hoffman trailed by a shot, making double bogey on the hole when his tee shot found the water:
That right there was the only water ball of the day at the 16th. And what terrible timing for Hoffman.
That opened up a can of worms for some of the biggest names in golf -- Justin Rose, Sergio Garcia, Rickie Fowler and Jordan Spieth, in particular -- who were just waiting for Hoffman to make a blunder.
When the third round ended, Hoffman's even-par 72 left him at 4 under and two shots out of the lead going into what is sure to be an epic final day of the 2017 Masters.
