Phil Mickelson insists he is nervous about competing at Augusta National this week, despite having won three green jackets and recording 11 other top-10 finishes in the year's first major championship.
Mickelson broke his major duck in the Masters in 2004 and went on to claim the title in 2006 and 2010, the left-hander also winning the 2005 US PGA Championship and last year's Open at Muirfield.
But a combination of indifferent form and injuries means the 43-year-old is not as confident as might be expected about his chances of matching Arnold Palmer and Tiger Woods by claiming a fourth victory here on Sunday.

"I'm nervous about this week because I always like coming into this week with a win," Mickelson said. "I like coming into this week being in contention a few times and having that confidence and experience to build on.
"But I have to give myself a little bit of slack because I have not been 100 per cent. Last week I felt great, which I was surprised by, because I had pulled a muscle in Texas and withdrew."
Rory McIlroy is favourite for the year's first major, trailed by reigning champion Adam Scott and three-time winner Mickelson.
Jason Day, Matt Kuchar, Zach Johnson, Charl Schwarzel and Sergio García are just some of the other names being touted.
