Excerpt: "The Case For Automated Strike Zones"

"I look at the catcher-framing data and see an indictment of home-plate umpiring, one so clear as to demand immediate change. What the framing data tells me is that umpires are not calling balls and strikes based on where a pitch crosses the plate, but based on what happens when it hits the catcher's mitt. What I see in the catcher framing data is the most clear evidence yet that umpires are not enforcing critical clauses of Rule 2.00."
