This definitely has great potential as a sports anime! This is an OVA special so don't walk into this thinking you would get to start a great sports series. This was created literally when the manga had a few chapters and honestly this could be a great anime in the future.
However, there is probably not going to be one so if I were you I would go check out the manga. It's still ongoing, so if you enjoyed this little episode, I'd get more content for it there.
If there were a series for this in the future I would definitely watch it, but for now, I guess I will just read the manga.
