(Reuters) - Fresh off his maiden major win, power-hitting golfer Bryson DeChambeau finds himself in a rarest of circumstances: He’s feeling relaxed.It’s a welcome reprieve for the meticulously data-driven world No. 6, who overhauled his body this year to add jaw-dropping power to his drives and claimed the U.S. Open crown by a six-stroke margin at a wickedly challenging Winged Foot course. “It was certainly for me personally a win that allowed me to be comfortable with being in my own skin and what I do,” said the 27-year-old American, who despite his age still felt the pressure of clinching a major title after six prior PGA Tour wins. Getting that “monkey off my back,” said DeChambeau, was a game-changer ahead of the Masters, which kicks off next week. “When I look at Augusta, I really think I’m going to be a lot more relaxed going into this tournament, I won’t be as forceful sometimes as I have been in certain majors that have caused me not to play my best,” DeChambeau told Reuters.
