ORLANDO, Fla. (AP) — Bryson DeChambeau survived the toughest final round at Bay Hill in 41 years and a gritty performance by Lee Westwood to win the Arnold Palmer Invitational. DeChambeau was helped by the long ball — with his putter. He made a pair of big putts for birdie and for par. And he won by one shot with a 5-foot par putt on the 18th green. He shot a 71. It was one of only three rounds under par, and the first time since 1980 that no one broke 70 in the final round at Bay Hill.
