Here is an example from 2019.

Yes, these are rare and it is not realistic for this to happen often. I also don't think it really matters, which is why this thread is somewhat annoying. In the realm of tweaks this game could use in order to make the AI more competitive I don't imagine allowing relief pitchers to hit too many times during a blowout is anywhere near the top of the list.
The AI likely doesn't have a concept of letting a bench guy get a random at-bat to appease them or to get them some work or maybe to avoid sending relief pitchers up there to embarrass themselves.
So, yeah, I think they should put this on the list of stuff they need to fix...way down there somewhere. Thanks for pointing it out.
