Arnold Palmer, considered one of the greatest golfers ever, has died at age 87.
The US Golf Association announced his death Sunday evening. He died at a hospital in Pittsburgh, the Post-Gazette reported, where he had been undergoing heart tests since Thursday.
Known as The King, Palmer was one of the most successful golfers on the course and also achieved status as a beloved household name. After winning The Masters four times, the Associated Press named him Athlete of the Decade for the 1960s. As his fame in the sport grew, so did a variety of business ventures and philanthropy.
