BLOOMFIELD HILLS, Michigan: Three-time major champion Phil Mickelson said on Tuesday that getting golf into the Olympics would have an impact that would dwarf the game's major championships.

"I think having golf an Olympic sport is exponentially more important to the game of golf than the majors," Mickelson told reporters.

Mickelson launches his campaign for a fourth major title today when the PGA Championship begins at Oakland Hills on the eve of the Opening Ceremonies for the Beijing Olympics.
