In 1929, the first night game in Putnam County was played in Ottawa. The first major league night game was played in Cincinnati in 1935. Plans for a new park in Ottawa were announced in 1950, and the Ottawa Community Boosters Club was formed in 1955 to raise funds to light the new baseball field. The first night game at the new Memorial Park was played in 1956. In 1965, the park was sold to Sylvania Electric and a farewell baseball game was held. Memorial Park was moved to its current location in 1986. The Ghost Players from the movie "Field of Dreams" played at Memorial Field in 2001 and 2002. In 2012, a windstorm damaged the baseball field lights. A lighting committee was formed in 2013 to raise funds for new lights, and the O-G Rotary Club helped secure a loan. The new lights were installed in 2018, and the dedication ceremony included a game between Findlay and Ottawa. The new lights have a brightness of 470,000 candle power or 5,896,000 lumens, and the cost of running them is less than the older style lights.
