What if the 9th hitter hits a double, the leadoff hitter of the inning steps in the box, and the defense appeals the 9th hitter missing first base and he’s called out? Does that count?
We need to get this thing codified otherwise people will be talking baseball all willy nilly with no thought to the miniscule, if any, ramifications of what they are saying.
In the hole, referring to something stashed away, such as the on-deck hitter, or, by inference, a hidden card in a card game, comes from “in the hold”, which the writer asserts was pronounced “hole” by British seamen. That shortening of words stands to reason, since the words forecastle and boatswain are pronounced “foc-sl” and “bo-sun”.
Linguistically, it actually does shorten (and simplify) things – which is why it is such a common “simplification”. There is no need to cut off the airflow to make the “d” sound and then restart it for the next utterance. The liquid “l” allows the speech to continue unimpeded and uninterrupted.
