Alva Fisher was a pitcher and shortstop as a baseball player for the All-American Girls Professional Baseball League. Fisher had only a five-year career, but she was one of the top players in the league. Fisher first began playing for the Rockford Peaches before switching to the Muskegon Lassies.
As a teen, Fisher began playing baseball for an all-state team in 1938. In 1945, she joined the Rockford Peaches team, playing first base. One year later, Fisher joined the Muskegon Lassies, where she transitioned to the role of pitcher. During her time with the Lassies, the team won both the regular season title and the championship title after defeating their competitor, the Fort Wayne Daisies. One of Fisher's best performances as a pitcher included pitching three shutout innings. During her last year with the Lassies, Fisher was named the best shortstop in the league. She had only 23 errors and turned 48 double plays in a single season.
After ending her baseball career, Fisher moved to San Antonio, Texas where she died of leukemia in 1973. Fisher has since been featured in the Baseball Hall of Fame and Museum, the San Antonio Sports Hall of Fame and the Texas Baseball Hall of Fame. The Alva Fisher Complex in San Antonio was also named in her honor.
