At what game # are rosters frozen?

...I've got a catcher injured for 15 games and made a player move for a 3rd catcher ... We are currently on games 136-138 and I don't want to go to the playoffs with 3 catchers. My starting catcher will be healthy for game #149 but I'm afraid that might be nearing the player movement cutoff. Anyone know the exact game # when player moves are frozen?

141. Starting with game 142 rosters are frozen.

Why pick up a third catcher? Unless your backup was a total scrub . . . the game won't let your last catcher get hurt.

Why pick up a third catcher? Unless your backup was a total scrub . . . the game won't let your last catcher get hurt.

Two reasons

1) you are platooning
2) your backup catcher is a horrible fielding DH type like Cliff Johnson
