Ben Hogan's first major win was in the 1948 U.S. Open. Hogan had been a successful amateur golfer, but he turned professional in 1934 and did not win his first major until he was 30 years old. The 1948 U.S. Open was held at Riviera Country Club in Pacific Palisades, California. Hogan shot a course record 65 in the first round and held the lead for the entire tournament.
