I have nothing but anecdotal information to add, having long since deleted that league, but I saw a similar issue in v12 with pinch hitters under MLB Quickstart. I poked around the forum and I recall finding a thread discussing the same issue. The consensus was that the issue only crops up under MLB Quickstart. Any other fictional or historical modes and pinch hitters pretty much 'feel' correct.
If I get a minute, I'll search and try to find that thread from the v12 forum... but I have to imagine somebody else would remember it as well... too many regulars around here.
