"Arnold Palmer — the pants-hitching, chain-smoking son of a greenskeeper who helped transform golf from an elite country club pursuit in to a sport for the masses, winning every major honor the game has to offer along the way — died Sunday at age 87, Palmer's company and the U.S. Golf Association said.

Alastair Johnson, chief executive of Arnold Palmer Enterprises, told The Golf Channel — which Palmer co-founded, among his many successful business enterprises — that Palmer died Sunday afternoon from complications of heart problems. (The Golf Channel is a unit of the NBC Sports Group.)"
