Let's go through some basic knowledge before I talk about it further...

Characters: Ash Ketchum & Casey
Canonical?: Fanon
Relationship status: Rivals
Also known as: Baseballshipping, SatoNana

What do I think?:

Uhhhhh... I'm not really too sure
They're rivals and Ash made fun of Casey because she didn't support the same baseball team as him... but it does look cute and gad some potential

I shall rate this ship?: 3/10

Thanks for reading, see you in the next chapter!!!
