The complex consists of four fields – one baseball, three softball – and is home to the Emporia State baseball and softball teams.

[1] The complex opened in 1992 after a local-based not-for profit foundation – Trusler Foundation – donated money to Emporia State University.

Both Emporia State baseball and softball teams compete here; Baseball on Glennen Field (named after Emporia State's 13th president), and softball on Turnbull Field (named after J. Michael Turnbull, who was president of Trusler Foundation).

[2] The two other softball fields – Cannon Field and Thomas Field – are named in honor of Joe Cannon who provided the land for the complex and Tom D. Thomas, treasurer and trustee of the Trusler Foundation.

[4] In 2014, nearly $400,000 was donated to improved dugouts and build a new ticket booth.
