This is no small thing. An inch in the strike zone, Bill James wrote, is worth 30 feet in the outfield. The de facto strike zone is, along with higher velocity, the key factor in today's stagnant, strikeout-laden version of baseball. Wide strikes and low strikes are changing the game, unbalancing it, with very little end in sight.
The framing data is the way out of this mess. It demonstrates clearly that umpires are not calling balls and strikes according to the rules of the game, but rather based on the crutch of catcher actions. This isn't out of laziness, out of a character flaw, out of a desire to bend the rules, but a concession to what has been true for decades: that human eyes cannot possibly track a baseball and render a decision on its position pursuant to the letter of Rule 2.00. Until recently, there wasn't much that could be done. Now, with PitchF/X in place, indicting umpires every single day, we have both the data to make the case and the technology to do something better. An automated strike zone will be more fair to all the players, while putting an end to a condition in which virtually invisible movements are as valuable as the acrobatics of a Gold Glove shortstop.
Commissioner Manfred, here's your first task: put automated ball-and-strike calling in place in time for the 2016 season.
