Clemson Tigers softball joined the Atlantic Coast Conference as a Division I varsity program in 2020.

Rittman spent the previous two years as an assistant coach at Kansas and USA Softball.

They were placed in a Regional with SEC champion Alabama and lost both games against the Crimson Tide.

Valerie Cagle recorded the perfect game by retiring all fifteen batters she faced in an 18–0 (5 inning) win over Mercer.

However, they did keep their streak of NCAA tournament appearances alive, but did not advance past the regional round.
