You think there are no consequences for missing putts on the practice green when you're a major champion? Guess again.
Ahead of this week's US Open at Pebble Beach, two-time major winner Zach Johnson was given a forfeit by his coach for failing to convert putts on the putting green.
His punishment? Stand at the side of the green and do jumping jacks.

Seems a bit harsh if you ask us but, then again, if the 43-year-old is holding the silverware at Pebble Beach on Sunday night, we doubt he'll care too much.
