The Tri-State League was the name of six different circuits in American minor league baseball.

National League Park, commonly referred to as the Baker Bowl after 1923, was a baseball stadium and home to the Philadelphia Phillies from 1887 until 1938, and first home field of the Philadelphia Eagles from 1933 to 1935. It opened in 1887 with a capacity of 12,500, burned down in 1894, and was rebuilt in 1895 as the first ballpark constructed primarily of steel and brick, and first with a cantilevered upper deck.
