mechwarrior2 found it on Youtube.
It came out in 1992.
Major League Baseball manager Sparky Smith is fired from his job with the Seattle Mariners. His attitude has gotten him into trouble with George, the owner of the Mariners, and no other team seems to want any part of him. The Olympic Games are coming up, however, and a spirit of glasnost exists in the post-Soviet Russia, which is trying to field its first Olympic baseball team.
Sparky reluctantly accepts an offer to move to Moscow to coach the players, many of whom don't even know the game's fundamentals...
Even though it's probably awful and not surprisingly obscure - I looked for public torrents. I couldn't find any.

ReadFanon put a torrent magnet link in their comment.
It must hard being a Seattle baseball fan out there lol, it’s like a trope now if you want to show someone truly washed up in baseball they get booted from the Mariners
