Golfers can change form overnight, but the following stars who struggled at the 2013 Masters are in the midst of slumps that won't disappear anytime in the near future.
With the year's next major just two months away, there is not a lot of time for these guys to rectify a slump, and the ensuing three golfers will not have their game going in the right direction in time for the U.S. Open.
Former world No. 1 Luke Donald is still looking for his first major, and it is more fair than ever to think he will never get it.
Donald has been playing well below his standards. He has played a light schedule, but that's why this Masters is so telling. Players of Donald's caliber aim everything toward getting ready for the majors, and Donald showed no signs of being able to get past his funk.
He finished tied for 25th at the Masters at two over. This is a respectable finish, but not for a golfer as talented as Donald.
Donald has now played in five Tour events this year, and he has finished higher than 16th in just one of them.
What convinces me that Donald's slump won't be going away anytime soon is his struggle with the putter.
Donald has always been reliant on his amazing putting to help him win. This year he is a pedestrian 76th in strokes gained putting, and he is showing no signs of turning that around.
It is going to be a battle for him to get that slump with the flat iron reversed.
I hesitate to put Phil Mickelson on this list because the guy is always insanely hard to predict. Phil is as streaky a golfer as I've ever watched.
That said, he has typically found a way to be at his best for the Masters, and Augusta suits his game well.
However, that wasn't the case this year. With a 76 and 77, Phil fired two of his three worst rounds ever at Augusta and he wound up tied for 54th at nine over par.
Padraig Harrington is having a rough year. With his missed cut at Augusta, he has now missed the cut in three of his seven Tour events this year.
Heading into the Masters, it looked like Harrington might be coming out of this slump. He finished 10th at the Texas Open.
However, he fired a 78 and 75 in his two rounds, and his 50 percent driving accuracy was his worst for any tournament this year.
This will be as big blow to Harrington, as he now has to go back to the range and reassess the direction of his swing. That is always a long journey.
