This game shown in that link is actually a different game. Atari had the unreleased prototype of the baseball game called Relief Pitcher on System 1 hardware, which would have probably been release in 1986 if it hadn't been scrapped. Then in 1992 Atari release a new baseball game with the same name. (this is the version that above link is pointing to). This newer version from 1992, however, was a completely different game, on completely different hardware. The only thing that the two share is the name "Relief Pitcher". Well, that and the fact that it's a baseball game. I'm the owner of this prototype game, by the way. And to the best of my knowledge there are two in existence.
