After
Jack Milne and his brother
Cordy Milne had finished first and third at the
1937 World Final (with another American
Wilbur Lamoreaux finishing second), the U.S. went into the speedway wilderness until the early 1970s, when international riders such as world champions
Barry Briggs and
Ivan Mauger from New Zealand began visiting the
Costa Mesa Speedway in Los Angeles.
Scott Autrey's appearance in the
1976 World Final in Poland, was the first American appearance since
Ernie Roccio had finished 15th in
1951. Autrey, who in the mid-1970s had campaigned hard and successfully to have American riders included in the
Speedway World Championship, signalled an American resurgence in speedway and was soon followed by others, such as
1981 and
1982 world champion
Bruce Penhall, brothers
Kelly and
Shawn Moran,
Bobby Schwartz,
Dennis Sigalos,
Lance King, 1993 Individual Speedway World Championship world champion
Sam Ermolenko,
Rick Miller, 1996 world champion Billy Hamill, and four times world champion
Greg Hancock all going on to be regarded as some of the world's best speedway riders. ==Major tournament wins==
