Gameplay of Dinger Derby.
The characters will participate in a game of batting practice, with various Mario characters like Shy Guys, Koopas, and Goombas cheering during the event. The characters will each be standing in front of home plate with their own bats and their own mechanical pitcher. The pitcher pitches a ball to the characters, in which they must hit with the bat. The pitching machines also pitches balls at different speeds and styles. The slower pitches allow the character to react at their own pace to them, while the fast balls require a faster reaction. At a couple of times during the minigame, the mechanical pitchers pitch a split ball, which requires the characters to pay attention when it is pitched. The character that hits the most pitched balls wins the minigame.
