The club finished with a league worst 4âÂÂ15âÂÂ4 record in their second MLS season in 2020, one shortened by the COVID-19 pandemic in Ohio.

On September 27, 2021, Stam was relieved of his duties. The team ended the season with a 4âÂÂ22âÂÂ8 record, with the team not being able to qualify into the MLS Cup Playoffs for the third consecutive season with a third consecutive last place finish in the overall table.
