League Park is located at E. 66th. and Lexington Ave in Cleveland. Built in the late 1800s, the ballpark was the site of numerous historic sports moments, including Cleveland Indians pitcher Bob Feller's first game (1936), the first unassisted triple play, and first grand slam in World Series history (1920 series). Many famous baseball players appeared and played in games at the park, including Babe Ruth, Ty Cobb, Satchel Paige and Lou Gehrig. The park, now a playground, is listed on the National Register of Historic Places.
