Under head coach Jill Thomas at Henderson State University, Mains enjoyed a breakout - albeit shortened - junior season that saw the Springdale native pour in a pair of 30-point performances en route to an All-Great American first team selection. Over her four-year career with the Reddies, Mains averaged 8.9 points, 1.3 rebounds and 2.2 assists per game (100 games) and shot 37 percent (286-of-773) from the floor. Mains' highwater mark came in that junior season when she went off in a 38-point performance in a win over Harding (Ark.) after another 35-point, nine-assist outing versus Southern Arkansas.

During her three-year career at Har-Ber High School under head coaches Sandy Wright and Jaime Green, Mains averaged 12 points per game a senior and earned consecutive All-Conference honors and an All-State selection in 2017.
