After every game or minigame, Bowser Jr. will wander around the map; if the player runs into him, they will be forced to play a game in the bottom of the 9th inning, with the player randomly chosen as visitor or home. If the player's team is the visiting team, then they will have the lead and must stop Bowser Jr. from mounting a comeback; otherwise, it is the player's job to mount a comeback. Beating Bowser Jr. earns the player 100 coins to use in the shop, while losing costs the player half of their coins. In the event of having an odd coin count when losing to Bowser Jr., the coins will be rounded up. Bowser Jr.'s team also has players from disbanded teams that the player can recruit; in which case the only mission objective is "Win the game."
