Throwing a softball?

Hey everyone, good to be back! Just have a quick question. My girlfriend is a softball player trying to make a college team next year, and im her only throwing partner. Should i take it real easy, or is there any way i can take advantage of this? Thanks!

The only drills i’ve ever done with a softball is for curveballs. just spin your curveball with a softball and the size of the ball forces you to stay on top. it helps me out a ton, as i do it before games.
