is something the matter with Phil Mickelson?

On August 10, 2010, Phil Mickelson announced that he had been diagnosed with psoriatic arthritis, a chronic inflammatory disease that is caused by an overactive immune system. Mickelson began treatment immediately and now has his arthritis under control. Since being diagnosed, Mickelson has been an advocate and spokesperson for arthritis awareness to encourage early treatment. Permanent damage to joint can occur if the disease is left undiagnosed and untreated.

Mickelson has a rough final round at the 2012 Masters. He took a nose dive down the leader board when he took a triple bogey on the par-3 fourth hole. His tee shot had ricocheted into some bamboo shoots. He decided to try to play the ball, rather than return to the tee to play his third shot. He finished two strokes behind Bubba Watson and Louis Oosthuizen.
