Bubba Watson rallied with two late birdies and closed with a 3-under 68 to win the Northern Trust Open in California by one shot.

Watson says he is happy about the way his games are evolving with the help of caddie Teddy Scott.
"Yeah for sure, we've been working on it hard. Slow process, instead of swing thoughts and swing, it's all about the mind. And so for me it's staying patient and Teddy (Scott) in my ear. And Teddy's (Scott) been a blessing with that. It's been a struggle over the five years but it's working in the right direction."
