With his go-for-broke style, Palmer became one of golf's first television superstars and helped push the game into the mainstream
Arnold Palmer, the charismatic face of golf, whose go-for-broke style attracted an army of fans called "Arnie's Army", died at 87 on Sunday, the United States Golf Association confirmed.
The cause of death was not immediately ascertained.
Palmer looked weak at the ceremonial first tee shot at the Masters in April this year, AFP reported.
"We are deeply saddened by the death of Arnold Palmer, golf's greatest ambassador, at age 87," the USGA said in a statement on Twitter.
Palmer established himself as "The King" of golf, as he was popularly known, from 1958 through 1964 when he won four Masters, one US Open and two British Opens.
Palmer's impressive style, and his celebrated rivalry with the American Jack Nicklaus and the South African Gary Player, helped popularise the game on television and he soon became a star.
