In his youth, Casper started as a caddie and emerged from the junior golf hotbed of San Diego, where golf could be played year-round, to rank seventh all-time in career Tour wins with 51, across a 20-year period between 1956 and 1975. Fellow San Diegan great Gene Littler was a friend and rival from teenager to senior. Casper won three major championships, represented the United States on a then-record eight Ryder Cup teams, and holds the U.S. record for career Ryder Cup points won. After reaching age 50, Casper regularly played the Senior PGA Tour and was a winner there until 1989. In his later years, Casper successfully developed businesses in golf course design and management of golf facilities.
