Marion Stadium

Marion Stadium (formerly Rent One Park and Mtn Dew Park) is a ballpark located in Marion, Illinois. It was the home stadium of the Southern Illinois Miners of the Frontier League until they folded in 2021. The Thrillville Thrillbillies were announced as a new team in Prospect League, and the ballpark was rebranded from Rent One to Mtn Dew, after an alternative spelling of the popular soft drink's name.

The park has also hosted the Ohio Valley Conference tournament in 2019 and 2023 to present (as of 2026) and the Great Lakes Valley Conference tournament from 2023 to present (as of 2026).
