UW-Oshkosh softball opened the Mary Beth Nienhaus Softball Complex in 1997 after spending the previous 16 seasons at the former field adjacent to Kolf Sports Center.

UW-Oshkosh has enjoyed much success since 1997, qualifying for the NCAA Division III Championship 10 times, advancing to the super regional round three times (2017, 2024, 2026), and reaching the World Series twice (2021, 2024).

UW-Oshkosh has hosted a Division III Regional three times (2023-25) and the WIAC Tournament five times (2000, 2010, 2021, 2024, 2026) since the Mary Beth Nienhaus Softball Complex opened.

Originally named the Oshkosh Sports Complex Softball Field, Nienhaus was renamed the YP.com Softball Park after the 2010 season and named the UW-Oshkosh Softball Park before the 2015 campaign.

As part of the Fields for the Future project started by local philanthropist Mary Beth Nienhaus, the home of UW-Oshkosh softball was dedicated the Mary Beth Nienhaus Softball Complex on Oct. 30, 2025. 

When the Titans moved across the river from the main UW-Oshkosh campus, the stadium included only the field. Dugouts were constructed by former head coach Sharon Panske’s father, Jim, in late 1997. The current building which includes the press box, office and storage space, restrooms, the ticket booth and elevated seating, was built in 2010. 

Since 1997, the Titans have posted a 207-82-3 (.714) record at Mary Beth Nienhaus Softball Complex and have recorded 26 consecutive years without a losing mark at home.
