If this indeed an issue it's going to have to be proven to the guys in charge, so I did some research and the results were interesting. First off, on average the first pitch strike happens roughly 60% of the time with the Phils Cliff Lee leading the way at 71.6% so the first thing that needs to be done is first pitch strike tracking to see if it does indeed mimic real life.
From there we get into the strategy of whether to swing or not to swing, and which option is better for the team overall, this article was absolutely fascinating and I suggest reading it, what it suggests is that even though BABIP(.315) for first pitch strikes is much better than overall BABIP(.297), batters are actually swinging less! To me this has everything to do with pitch count and the desire of nearly every MLB club to get into the opponents bullpen. What do you guys think? Here's the article

Another theory I have is this, maybe it's not the first pitch strikes that are the problem, maybe it's that hitting is too easy and that's what needs to be lowered with sliders. Checking this is easy as well, calculate BABIP for first pitch hits.
