Phil Mickelson won the 2013 British Open Championship with a superb final round as the other contenders, including Tiger Woods, faded from contention.
Mickelson captured the famed Claret Jug for the first time and his fifth major championship with a 5-under 66 Sunday, tied for the best round of the week.
The left-hander birdied four of the last six holes to win by three shots and emphatically erase the memory of this year's U.S. Open heartbreak.
"This is such an accomplishment for me," Mickelson said. "I never knew if I'd be able to develop the game and the shots to play links golf effectively."
"To play what is arguably the best round of my career, to putt the way I putted, to shoot the round of my life, it just feels amazing to win the Claret Jug."
Mickelson, 43, has eight runner-up finishes in golf's four major tournaments, but has now won three of the four in his remarkable Hall of Fame career.
