Bob Tereshinksi Stadium at Riverside Field in Yankton, S.D., the home facility of Mount Marty Baseball will play host to the Morningside Bracket of the Great Plains Athletic Conference Postseason Tournament, thanks to the graciousness of Mount Marty University.

The newly renamed Bob Tereshinski Stadium at Riverside Field is located right along the scenic Missouri River and features a turf infield, completed in 2014. Situated next to Riverside Park, the baseball field is at the intersection of Pearl and Levee Streets.

In 2023 Riverside Field and YBA worked on a $150,000 Improvement Project at Riverside Field which increases safety measures for players and fans such as turfing entire warning track, installing new interior fence to enclose the bullpens, renovating both dugouts, and installing heating and cooling in the press box.
