Bubba Watson is confident his new-found mental strength can help him claim a first WGC-Cadillac Championship title after twice finishing runner-up.
The world number two came second in 2012 and 2014 at the Doral Golf Resort and Spa course, missing out on the crown by one shot from Justin Rose and Patrick Reed respectively.
He returns to Miami on Thursday looking to go one better and claim a second win on the PGA Tour this season, with the 36-year-old confident he is ready mentally and physically to go on the attack from the first hole.
"For me it's not about ability," said Watson. "It's never been about ability. It's about my mind.
"If I get my mind in the right place, there's not a shot I can't hit. There's not a golf course that can beat me. It's about being the right focus, the right energy level. It's all that wrapped into one for me.
"When you step on that hole, is the bad swing [at fault for] the ball that went in the water or the ball that's going to go in the trees? Is the bad swing because of a swing? Or is it because your mental issues? And all of mine are mental issues.
"The physical part, I've got it. We can all hit tee shots. We can all hit iron shots. We can all make putts.
"It's about the mental focus, and that's where my game is going to improve and that's where it's improved over the last year and a half six months."
Watson will be in esteemed company on the opening two days at the tournament having been drawn alongside world number one Rory McIlroy and Henrik Stenson.
