The 35-year-old Watson had his wife and young son for company as they celebrated his big win.

Watson beat the experienced Jordan Spieth, scoring a three-under par 69 on Sunday to finish 72 holes on eight-under 280.

"A small-town guy named Bubba now has two green jackets. That's pretty wild," said the visibly cheerful Watson in the post-tour ceremony.

"The first one for me, it's almost like I lucked into it. This one was a lot of hard work.," said Watson, while talking about the coveted green jacket that he won.

Watson became the 17th multiple winner of the Masters with his sixth career title.
