A nice little project, and the art is really lovely!
However, I for the life of me could not figure out how to consistently get home runs. I could get hits, but trying different timings and positioning did not seem to change the result. I got lucky maybe once or twice but that was about it.
I think adding a tutorial or a bit of feedback after a swing can help the player get better at hitting things consistently. Something like a "too early!" or "too late!" message can be very helpful with keeping players engaged! I also think you guys have some great art. It would be cool if some of the art was featured more in the game.
I think the scope is well thought out for a game jam, with some potential avenues for future development (such as more batters).
But I don't really know what it has to do with corruption.
