Do you mean video games or tabletop?
Because I guarantee there's tabletop RPGs for various sports. But the only video game I can think off of the top of my head was Base Wars for the NES, where you could upgrade robot baseball players with different parts, which kind of bordered on being an early RPG-style game.
