Louis Oosthuizen won the 2010 Open Championship at St Andrews in runaway fashion.
If the group of players at 50-1 odds was big and strong, the group at 40-1 is even bigger and stronger.
In order of their world rankings, Jason Dufner (seventh), Hunter Mahan (10th), Adam Scott (12th), Martin Kaymer (14th), Dustin Johnson (15th), Phil Mickelson (16th), Rickie Fowler (19th), Louis Oosthuizen (20th), Ian Poulter (27th) and Ernie Els (40th) are the players at 40-1 odds.
Dufner has been outplayed only by Tiger Woods the past couple of months. Two wins, a second place and a T4 at the U.S. Open have earned him the seventh spot in the world rankings.
But he will have to make the cut for the first time at The Open before he starts thinking about winning it.
At The Open Mahan's lone bright spot was his T6 finish in 2006, so he has some work to do to win here.
At least he has won twice this year and has been gaining momentum, with T11 and T8 finishes on his last two tournaments.
Scott started the year slowly but has picked it up recently and comes from a third-place finish at the AT&T National.
That is good news for him: His only top-10 finish at The Open came in 2006, when he finished T8.
Kaymer is on the wrong side of the momentum line. He has only one top-10 finish in his last nine tournaments.
At The Open he has finished T7 and T12 the past two years, so you should expect an improvement on his recent work.
Johnson won the FedEx St. Jude Classic this year after resting his back but then missed the cut and finished T44 and T33 at his next tournaments.
He finished T2 last year and had a great shot at winning.
When he is at his best, he can win anywhere against anyone.
Mickelson gave it a big run last year to finish second, which was his best finish at The Open and his only other top-10 finish, as he placed third in 2004.
The Open is not his best tournament, but if he repeats last year's performance, he has a chance.
Like his game, it's a gamble predicting whether he has a chance or not here.
Fowler finally won a tournament this year, which was expected to be his breakthrough performance.
But he has been dropping down the finish line ever since.
He finished T5 last year and T14 the year before. If he can stop the down slide in finishes and regain his the form from a couple of months ago, he will contend.
Oosthuizen won in runaway fashion in 2010 at St. Andrews. This year he had a stretch in which he finished third, second—at The Masters—and first, looking like the hottest player on tour.
But he has since cooled down, with one top-20 finish and four missed cuts.
He has plenty of work to do to contend.
Poulter finished seventh at The Masters and has a couple of top-10 finishes since, including his T4 finish at the Alstom Open de France, his last start.
His second-place finish in the 2008 Open is his lone bright finish here. He must find some consistency to fare well.
Els has been showing signs of his old self this year, after last year's downfall. He is back up to 39th in the world ranking and finished ninth in his last start at the U.S. Open. In the last decade, he won The Open once, had five top-five finishes and placed two other times in the top 10.
He has missed the cut both times this decade, but taking into consideration his recent form, there is now way you can discount the Big Easy.
