Great analysis, paint.
So how do you do the strike zone? I think that's the hard part.
Pay attention to the open sky
This shows that it isn't consistent. The harder you throw, the smaller your strikezone is.No MLB umpire is perfect, but most are damn good. That each man has a bit of a varying strikezone is OK by me and most teams (just be consistent).
I want the game I love to be decided by the players on the field. Not the guy wearing the umpire hat.I want baseball types ruling baseball games. Not a Silicon Valley type that has never played the game nor understands the importance of the game and it's history. Wendelstedt can call the game I attend while Gates can be responsible for the software I utilize to study the stats from that game.
For what it's worth, the Pitch F/X setup is much less complex and probably costs 20% of what I suggested above. It's diminishing returns, and it all depends on how accurate you need the measurement to be. An inch will cost you millions...

What if this wasn't a rhetorical question?
All models are wrong. Some of them are useful.
I hate to beat a dead horse, but the computerized strike zones are dependent on humans calibrating the zone before each at-bat. There is some definite wiggle room for being off by an inch or two with each player, and worse is that because it's only calibrated before the plate appearance, a slight shift in batting stance can throw off the zone even further.

So lets assume that 25% of Chapman's 98+ taken strikes are balls.
Is it too much to ask to see some photographic prove?
Lets take it a step further. If you are a fireballer getting jerked around why not make a huge stink in the press? 25 percent error rate is beyond comprehension.
But it is pretty simple, if you accept that the Pitch F/X system is incredibly accurate (and MLB, MLB Teams and every television station that covers the games all do), then what the author is saying is true.
