What MLB confirmed
An exclusive Avengers: Doomsday preview is coming during World Series Game 1. MLB made that promise in an October 22 post on its verified Instagram account.
The wording matters for fans planning to watch: the announcement calls the footage an exclusive preview. It does not identify it as a full new trailer or give an exact slot during the game.
The US viewing time
FOX lists Game 1 for October 23 at 8pm ET (5pm PT).
Treat that as the game schedule. The preview could appear during the broadcast, and the MLB post does not name a particular inning or commercial break.
What to check after it airs
The official post gives no online upload time or footage length. For a standalone version after the broadcast, check MLB and the film’s official channels for an actual release announcement.
