Cooper Park hosted its first game on March 25, 2007, a Millersville 16-6 win over Philadelphia University. The park features include a new scoreboard in left-center field, a climate-controlled press box with facilities for audio and video broadcasts, a grandstand to support 250 fans, a state-of-the-art irrigation system and a sound system. For the players, there are batting cages in right field and along the third base line as well a bullpen area for each team. It is considered one of the top home fields for any school in the PSAC. The initial project took four years to plan and build and $1.7 million to complete. In the fall of 2016, a FieldTurf infield was installed along with renovations to the dugouts.
The program moved into a clubhouse directly behind the grandstand in the spring of 2012. Formerly offices, the building was reworked to include lockers, meeting rooms and coaching offices.
The park, known as Marauder Park for the majority of existence, received an official name change on April 20, 2013. A dedication ceremony revealed the name as Bennett J. Cooper '67 Park in honor of the former Marauder baseball player for his generous gifts to the program. New signage on the press box as well as a plaque and a banner in left-center field were unveiled.Â
