Aim for a Home Run to Turn the Tide!!) is the 28th episode of the Sun & Moon series, and the 967th episode of the Pokémon anime. It first aired in Japan on May 25, 2017 and in the United States on August 26, 2017.
It’s the season for our heroes’ favorite pastime: Pokémon Base! Professor Kukui has arranged a special lesson for them, complete with a guest coach: Oluolu, the star player of the Magikarp team that just won the Pro League season.
After the students’ game, Team Rocket shows up to demand a Pokémon Base battle—with the winning team getting the star’s autograph. Oluolu teams up with the students, and it’s a close match until he unleashes his secret weapon: his Snorlax partner’s Z-Move, Pulverizing Pancake!
In appreciation for a good game, Oluolu offers Jessie his autograph anyway—but Bewear charges through and carries Team Rocket off before she can accept!
At Professor Kukui's house, Ash, Rotom, Rockruff and Professor Kukui are watching Pokémon Base. They watch as the pitcher throws a ball at Gyarados who hits the ball into the wall. Oluolu takes his place to bat knowing he must get Gyarados and himself home to win the game. Oluolu hits the ball and sends it out of the park. The next day at School, the class discuss the game. Professor Kukui tells them that Pokémon Base will be what today's class will all be about. They have invited Oluolu to teach the class and are joined by Samson Oak. Outside, Kiawe, Mallow, Lillie and there Pokémon are one team with Ash, Sophocles, Lana their partners on the other. The adults are acting as commentators as Oluolu explains the rules. Kiawe pitching the ball but Ash misses it. Soon the teams switch with Kiawe batting. Pikachu throws the ball which Kiawe hits. Sophocles runs around and catches the ball.
The game continues and Lana is the last one to bat. She surprises everyone when she hits the ball hard, sending it out of the park and giving them a home run. A disguised Team Rocket are walking past with Jessie holding a picture of Oluolu. Meowth is hit by the ball. They run into the school where Jessie spots Oluolu. Ash's team are declared the winners as Jessie makes their presence known and recite their motto. Jessie is keen to get Oluolu's autograph but they don't believe her. Oluolu gets involved and suggests they settle the dispute by having a game of Pokémon Base, which Jessie agrees to. Discussing tactics, James notes that they have a disadvantage with Oluolu on the other team. Jessie hits the ball and starts running the wrong way, causing Jessie to be out. The teams switch only for Mimikyu to throw the ball hard. Ash accuses Team Rocket of cheating, so they change pitcher. Kiawe is struck out as Meowth chuckles at his performance. Oluolu hits the ball and reaches safety. To win the game, Snorlax has to get home as Meowth vows that they will win.
The ball strikes Snorlax's bat and Mareanie grab its. Mareanie runs over to James and hugs him affectionately. Oluolu makes it home but Snorlax has yet to run. Oluolu pulls out his secret weapon, a Z-Ring and powers up and has Snorlax use Pulverizing Pancake which sends Snorlax running for home as Meowth throws the ball towards Wobbuffet. Wobbuffet catches the ball, only to be flattened by Snorlax as Professor Kukui declares Snorlax safe. Professor Kukui wraps up the game announcing the school has won as Jessie cries over not getting Oluolu's autograph only for Oluolu to come over and give her the autograph for a wonderful game but as Jessie goes to take the autograph, she along with the others are scooped up by Bewear who arrives to carry them off to its den, preventing Jessie from getting Oluolu's autograph. After watching Team Rocket go, Oluolu thanks everyone for bringing back memories from when he began playing Pokémon Base.
Rotom narrates the ending of this episode instead of the narrator. However, the narrator still narrates the beginning of this episode.
The contraption that Meowth wears on his body during a flashback to his training is a reference to the series Star of the Giants, where the main character wore a similar contraption on his body, in order to straighten out his arms, making him better at playing baseball. Kiawe wears a similar device during a later episode.
