Well, we must have different definitions of analytics. What you call analytics, I call plain old common sense backed by historical data.
What I call analytics is the study of pitch locations, spin rates, velocities, extent of up/down and/or left/right movement, pitch release point etc. Also, batter's launch angle, bat swing velocity, batted ball exit velocity, hitter's spray charts. A pitcher's tendency to throw a particular pitch in a particular count in a particular location. Defensive alignments for batters given historical hit locations on any given pitch type thrown, etc.
There is much more.
