Baseball Zombie is a zombie that appears in Homerun Derby, which is exclusive to the Nintendo DS version. It requires one instant kill or a basketball shot to defeat. As a result of this, its toughness is unknown. Similarly to many other zombies, Baseball Zombie's main target is the house. When the player reaches at least 27 home runs, its speed will increase.
- When the player has 27 home runs, it will run faster than Dolphin Rider Zombies.
- At the bottom of the page with the online version of the game, the player can see this zombie, although it does not appear in the online version nor in the PC version.
- In its HD picture, it has a glove, but in the game, it does not.
