Baby Steps, Days (TV) Recommendations
Both are sport anime. Both have a week MC at the beginning, but slowly get better with dedication and hard work. Watching the first episode of Days just screams Baby Steps to me. Enjoyed Baby Steps a lot, so hopefully Days can be just as good.
They both consist of an MC who knows nothing about the sport at first.
The MC Gradually improves in the sport through hard work and determination.
MC makes friends by working hard and proving everyone wrong.
Both MC's are quiet at first, but open up later on.
