The Home-Run Stadium is a stage used in the Home-Run Contest. It is comprised of a grassy stadium of extreme length (infinite in Super Smash Bros. Brawl) with a single small platform where a Sandbag sits. A Home-Run Bat is next to it.
There is a wall to the left of the platform that Sandbag can be bounced off of; however, getting the right bounce to avoid a "No Distance" is difficult. While the stage does eventually end, hacking is required to ever reach that far.
 In Super Smash Bros. Brawl
An energy barrier surrounds the platform that deactivates when the timer reaches 1 second, making it easier to avoid having Sandbag fly off prematurely. However, the shield will break if Sandbag collides with it six times. Via hacking, this stage can be used on Versus Mode. The stage doesn't seem to have a blast line and a Basic Brawl will not have an end unless a player leaves the game.
