The 2012 British Open had its share of disappointments, but none are worse than failing in the tournament's final round.
Adam Scott and Tiger Woods know how it feels for sure. Without their fourth-round struggles, we may not be talking about Ernie Els as this year's champion.
Let's take a look at the three most disheartening performances from Sunday's Round 4.
Scott bogeyed four holes down the stretch. He didn't blow one, two or three chances. Scott missed four potential tournament sealers.
Instead of locking them down, he allowed Els to win The Open Championship by one stroke. It was a collapse of seismic proportions.
It's not like those four bogeys were Scott's only missed changes. He bogeyed three holes prior to that, and he only managed to score birdies on two holes. That's not championship golf.
Scott played well enough to win this tournament for three rounds, but he failed to play well when it mattered the most.
Woods could have won this tournament. A triple-bogey on hole No. 6 in the fourth round negated any glimmer of hope in that area.
At that time Woods was five strokes back of the lead. He was poised to charge up the leaderboard, but he needed something major to happen right there.
Woods will remember his play on that one hole until the PGA Championship in August. He played extremely well entering this weekend's play, but the moment became too big for him.
Maybe he will claim his 15th career major in August, or maybe he won't.
McDowell shot a 75 in Round 4, but he played very well in the other three rounds. He shot a 67 in Round 1, a 69 in Round 2 and another 67 in Round 3.
That sounds like a contender to me, but he had to finish the job. Instead of doing that, McDowell bogeyed seven of his final 18 holes. He didn't even look like the same golfer on Sunday.
He still finished tied for fifth and two-under par for the tournament, but he could have finished much higher. If he had lived up to expectations in the tournament's final day, who knows how high he would have finished?
