WATCH: Double bogey on 18th hole costs former Bulldog Kevin Kisner at British Open

Former Georgia golfer had a chance to head into the weekend as the sole leader of the 147th Open Championship at Carnoustie, but as has happened to so many golfers before him, the Barry Burn got him.

Kisner had improved upon his day one lead by shooting 3-under par through 17 holes in the second round at Carnoustie, bringing him to an 8-under total. A par on the 18th would have given him a two-stroke lead over Zach Johnson, already in the clubhouse. But a tee shot into the rough on the par-4 18th left the Barry Burn standing between him and the green, and his second shot landed in the drink.
