I don't think the ball is juiced necessarily.
For one thing, pitchers sit in the mid-90s and because they are not saving anything for the late innings, they can still reach back for something extra. If a hitter makes contact...well the fast it comes in, the fast it goes out.
Secondly, I think the pitch clock has more of a negative affect than first glance as well
Finally, I still think they are searching for an advantage, but pitchers are monitored much closer for using sticky stuff.
