Catcher's Mitt vs. Fielder's Glove

[Dave Reed]

Then the MLBUM - which is the official interpretation - says it has to be a catcher's mitt, not a glove ot 1B mitt. I didn't make it up, I did a copy/paste.

But the MLBUM says nothing about what a catcher may use when he starts the game--only that he can't substitute part way through the game.

Again, I suppose the reason for this interp is to keep catchers from using a regular glove during intentional walks. A paragraph requiring a MLB catcher to use a catcher's mitt while receiving ordinary pitches would seem to me to be a waste of ink.
