And I still don't get the connection between this situation and an injured player trying to work the pitcher for a walk. Those dots still aren't connected (at least for me).
Not saving time? How about the time it takes him to get to first base and the time it takes him to get off the field once he's replaced as opposed to the time it would take him to simply walk back to the dugout from the plate? Not necessarily a huge savings in time (and other steps can be taken to speed things up even more), but it still amounts to some savings in time.
Further, I don't know why you think a new ball is put in the game after a walk, unless you are requiring it as some ridiculous sort of COVID-19 precaution or something.
You've got me scratching my head over this as I try to at least appreciate the logic of your position. And it still escapes me. Perhaps we truly can only agree to disagree.
It looks to me like you are in the minority on this and IMO it probably won't be long before "walk and sit" becomes the rule - at least in the Conference.
