Three-times major champion Billy Casper died on Saturday at the age of 83, the US PGA Tour has announced.
The tour said on its website that Casper died at his home in Springville, Utah. The cause of his death was not disclosed.
Casper won the 1959 and 1966 US Opens, and also won the 1970 US Masters in a playoff.
Those major wins were among his 51 victories on the PGA Tour between 1956 and 1975, seventh on the all-time list.
Casper, eight-times an American Ryder Cup team member, was inducted into the World Golf Hall of Fame in 1978.
He might be best remembered for his US Open victory at the Olympic Club in San Francisco in 1966 when he overcame a seven-stroke deficit over the final nine holes of regulation before beating Arnold Palmer in a playoff.
