After the Electabuzz's 10th loss in a row, Casey is upset about the fortunes of her favorite baseball team. With star pitcher Corey Demario sidelined by a shoulder injury, there's no relief in sight for the Electabuzz! But when Casey sees a runaway Charizard in the park, she realizes its Trainer is none other than Corey Demario himself. During his recovery, he's helping out his father, a Pokémon rancher. The Charizard, Don, really belongs to a boy named Benny, but Corey raised it—and now he's trying to help Don, who's so insecure it can't even fly or use Flamethrower. Naturally, Casey offers to help Don regain its righting spirit.

Back at the ranch, Corey's dad tells Casey that Corey's arm is fine, but Corey's lost the confidence to go back to pitching. Helping Don was supposed to help Corey too, but the plan hasn't worked, so now it's up to Casey. Casey starts by making everyone do some cheerleading, then orders Don to battle.
