started by pitcher Cy Young. During 1914 to 1915, the Toledo Mud Hens of the minor league American Association were temporarily moved to League Park, to discourage the Federal League from trying to place a franchise in Cleveland. During their two-year stay, they were initially known as the Bearcats, then the Spiders, reviving the old National League club's name. The Indians hosted games four through seven of the 1920 World Series at League Park. The series, won by the Indians five games to two, was notable as the first championship in franchise history, as well as for game five, which featured the first grand slam in World Series history and the only unassisted triple play in postseason history. In 1921, team owner "Sunny" Jim Dunn, who had purchased the team in 1916, renamed the park "Dunn Field". When Dunn died in 1922, his wife inherited the ballpark and the team. When Dunn's widow, by then known as Mrs. George Pross, sold the franchise in 1927 for $1 million to a group headed by Alva Bradley, the name reverted (in 1930) to the more prosaic "League Park" (there were a number of professional teams' parks generically called "league park" at the time). From July 1932 through the 1933 season, the Indians played at the new and far larger Cleveland Stadium. However, the players and fans complained about the huge outfield, which reduced the number of home runs. Moreover, as the Great Depression worsened, attendance at the stadium plummeted. After the 1933 season, the Indians exercised their escape clause in the lease at the stadium and returned to League Park for the 1934 season. The Indians played all home games at League Park for the 1934 and 1935 seasons, and played one home game at Cleveland Stadium in 1936 as part of the Great Lakes Exposition. In 1937, the Indians began splitting their schedule between the two parks, playing Sunday and holiday games at the stadium during the summer and the remainder at League Park, adding selected important games to the stadium schedule in 1938. Lights were never installed at League Park, and thus no major league night games were played there. However, at least one professional night game was played on July 27, 1931, between the Homestead Grays and the House of David, who borrowed the portable lighting system used by the Kansas City Monarchs. By 1940, the Indians played most
