2010 U.S. Open, Pebble Beach: Johnson began the final round with a three-shot lead after a third-round 66, but he quickly vanished from the leaderboard by making triple bogey on the second hole — when he had to swing out of thick rough lefthanded — followed by double bogey on the third, when his tee shot went left and couldn’t be found. He never recovered, finishing eighth after shooting 82.
2010 PGA Championship, Whistling Straits: Johnson made birdie on the 16th and 17th holes to go up by a stroke, but his tee shot on 18 went into the gallery. What he didn’t know is that his shot was ruled to have landed in a bunker, and he was given a two-shot penalty for grounding his club, turning a bogey into a triple bogey and costing him a spot in a playoff with Martin Kaymer and Bubba Watson.
2011 British Open, Royal St. George: Playing in the final group with Darren Clarke, Johnson was two strokes off the lead through 13 holes. Wanting to put pressure on Clarke, he tried a 2-iron on his second shot on the par-5 14th, but he pushed the ball right and out of bounds, leading to a double bogey that sealed Clarke’s three-shot victory. Johnson finished in a tie for second with Phil Mickelson.
2015 U.S. Open, Chambers Bay: Again playing in the final group, Johnson had a shaky back nine but still had an opportunity to win when Jordan Spieth made only birdie instead of eagle on the par-5 18th, giving him a one-shot lead. Johnson also had an eagle putt to win from about 12 feet, but he missed it … then missed the 3-foot birdie putt coming back to give Spieth the championship.
