Immelman held it together around Amen Corner and stretched his lead to as many as six shots on the back nine, taking the life out of a Masters that began with so much hype.
A two-putt par on the final hole gave him a 3-over 75, matching the highest final round by a Masters champion. Even so, it was good enough for a three-shot victory over Tiger Woods, whose hopes for a calendar Grand Slam ended with a thud.
Woods never got within five shots of the lead, twice missed birdie putts inside 8 feet and had to settle for a 72 and his second consecutive runner-up finish in the Masters.
"I learned my lesson there with the press," said Woods, who started the talk about a Grand Slam by stating three months ago that winning all four majors in the same year was "easily within reason."
