Play by play on PA
Did they really have play-by-play over the PA systems at baseball games in the 1940s? When I went to Detroit Tigers games in the 1980s, I only heard announcements about who is coming up to bat next, and maybe the score at an inning change.
If they wanted to do play-by-play for explanatory purposes, they could have cut to a radio or to the broadcast booth. Doing it on the PA seemed unrealistic to me.
