Look at the picture above.
Rickie Fowler missed this putt at the US PGA Championship on Friday.
The 31-year-old American stepped up to tap-in on the par-4 sixth, his 15th hole of the day after starting his round on the tenth.
His eight-foot putt for par narrowly missed and he had just inches left for bogey. A tap-in, basically.
Only he tapped it too gently, barely moving the ball and almost missing it altogether. That turned what should have been a bogey into a double - and a costly one at that. Watch what happened...
Bad enough under any circumstances but truly awful when you consider the context.
After opening his title tilt at TPC Harding Park with a disappointing three-over 73, he was four-under for his round and one-under for the tournament as he played the sixth. By the time he walked off the green, he was one-over.
He ultimately signed for a one-under 69 to lie two-over for the championship - missing the cut by a shot.
Fowler, a five-time winner on the PGA Tour, was making his 41st major start but is still searching for his first victory in the game's marquee events.
