Semi–professional level baseball in Willows began in 1900 with the Willows Giants.[1]
In 1948, Willows sought to gain a minor league franchise, with the effort supported by local businessmen John Baker, Larry Cummins, Arno Poggi and others, who eventually helped secure a team to be based in Willows.[1]
Beginning play in the 1948 Far West League, the Willows Cardinals placed fifth with a 62–63 record, playing the season under managers James Tyack and Bill Krueger. The Cardinals finished 8.5 games behind the first place Oroville Red Sox in the final Far West League regular season standings. The team did not qualify for the playoffs.[4][5]
Continuing to play in the 1949 Far West League season, Willows qualified for the playoffs. The 1949 Cardinals placed third as the league lost two teams during the season, completing the season playing as a six–team league.[5] With a 68–68 record under managers Bert Bonomi and Fred Fass, the Cardinals finished 15.5 games behind the first place Pittsburg Diamonds in the final regular season standings. In the playoffs, eventual champion Pittsburg defeated Willows three games to two in the first round.[6][7][5]
In their final season of play, the 1950 Willows Cardinals finished last eight–team Far West League.[5] With a record of 54–85 under manager Ray Malgradi, Willows finished 33.0 games behind the first place Klamath Falls Gems, missing the playoffs.[8][5]
Willows permanently folded from minor league play following the 1950 season, as the Far West League reduced to six teams in their final season of 1951.[9]
Ballpark
The Willows Cardinals hosted home minor league games at Ajax Field. The ballpark was located at North Culver Avenue & West Walnut Street in Willows, California.[10] Ajax Field was named for Tom Ajax, a local businessman and long-time manager of the local Willows Giants team, who died in 1949. The ballpark grandstand was completely destroyed by fire in 1961.[1]
