US golfer Arnold Palmer viewed as one of the greatest players in the sport's history, has died at the age of 87.
Palmer died in Pittsburgh, Pennsylvania, where he had been undergoing heart test.
The United States Golf Association also confirmed his death in a tweet calling him "golf's greatest ambassador".
During a long career he won more than 90 tournaments worldwide.
He was one of golf's most dominant players in the late 1950s and early 1960s, winning seven major titles over seven seasons.
He also notched up 62 PGA Tour wins.
(2/2) It’s hard to imagine golf without you or anyone more important to the game than the King.
