The City of Tampa acquired the Cyrus T. Greene property in 1931 and named it in honor of the executive secretary of the Tampa Urban League. By the 1940s, the baseball field there was known as 22nd Street Park and served as the home field for several semi-professional teams in the Florida State Negro Baseball League from the mid-1940s to the 1950s, including the Pepsi-Cola Giants, Tampa Rockets, Tampa Grandstanders, Tampa Black Smokers, Tampa Blue Sox, Tampa Athletics, and the Tampa All Stars. In 1947, the Tampa Rockets won the league championship. From the mid-1950s to the early 1960s, the Tampa Grays of the African American West Coast Baseball League played home games on this field. Negro League teams, including the New York Black Yankees and the Indianapolis Clowns, trained in Florida and sometimes played there. Several Tampa star players whose home field was 22nd Street Park went on to play for Negro League teams during their careers, including Hipolito Arenas, J.B. Broome, Clifford "Quack" Brown, Benjamin "Billy" Felder, John "Bey" Gibbons, Walter "Dirk" Gibbons, and Raydell "Lefty Bo" Maddix. Because Black players were restricted from Major League baseball until 1947, the Negro League represented the highest level of accomplishment for Black players. In 1968, Billy Reed, Benjamin Rouse, George Sullivan, and James Hargrett, Sr. organized the Belmont Heights Little League, which played its games at Cyrus Greene Park. Belmont Heights reached the championship games of the Little League World Series in 1975, 1980, and 1981, played in the semi-final round in 1973, and a Belmont Heights team played in the Senior League World Series game in 1979 and won the Junior League World Series in 1982. Future major leaguers Derek Bell and Gary Sheffield played on the 1980 team, and future major leaguers Dwight Gooden, Floyd Yuma's, and Vance Lovelace played on the 1979 Senior League team. Cyrus Greene Park, long known as 22nd Street Park, became a lasting center of African American baseball in Tampa during and after segregation.
