From Bulbapedia, the community-driven Pokémon encyclopedia.
Three episodes have featured baseball as a major theme:
* The introduction of Casey in ''[[EP118|The Double Trouble Header]]'' contained many baseball references. Aside from the title itself, Team Rocket had a baseball themed motto and the final confrontation took place on a baseball field.
* In ''[[SS011|A Date with Delcatty]]'', [[Georgio]] wanted to go on a date with
[[Misty ]] to the Starmie-Electabuzz game.
* Casey managed to help her team in ''[[SS017|Those Darn Electabuzz]]'' by helping their star pitcher to regain his confidence.
