MLB The Show 21 Receives Massive New Game Update, Patch Notes Revealed Developer Sony San Diego has been hard at work fine-tuning MLB The Show 21 ever since the game released in early access two weeks ago today. Although not every issue has been fixed at this point--mainly in regards to the servers--a major new update has been released as of today that should make the sports sim that much more polished. The third game update for MLB The Show 21 has rolled out recently across all platforms and brings with it numerous changes. Per usual with an update of this sort so quickly after launch, much of what has been included in the patch is mainly bug fixes and other tweaks that help rectify some lingering balance issues.
