Webb Simpson: 'I never doubted myself'

Shriners Open champion Webb Simpson has said that it was only "a matter of time" before he ended his 16-month wait for a fourth PGA Tour title.

The 28-year-old American stormed to a six-shot victory in Las Vegas to clinch his first title since winning the US Open in June of last year.

Simpson admitted frustration at ending the 2013 season without a win, but said that he felt confident that his game was improving.

"It was a little frustrating," Simpson told the PGA Tour's official website.

"My main goal every year is to get better. I thought I was getting better; I just wasn't in contention enough.

"I never really doubted anything. I just thought it was a matter of time before it happened."

The Shriners Open counts as the second tournament of the 2014 season due to a wraparound.

The next event is the CIMB Classic at Kuala Lumpur Golf & Country Club, starting on Thursday.
