We are in the midst of a turbulent period in baseball history when it comes to technology. Major League Baseball is slowly, laboriously, painfully incorporating instant replay into its structure; at the moment, only for were-they-or-were-they-not home run calls, but that won't be the case for long. I predict that in the next few years we are going to see replay incorporated in safe/out calls at the bases and fair/foul calls down the lines. Reasonable people may disagree about how this should be implemented (concerns include pace of play, how call reversals should be handled, whether we need a "booth umpire"), but I think most fans want to see correct calls. This is all about improving the quality of the product on the field, and I think it is tough to argue that blown calls improve that product. All of which got me thinking about the next logical step regarding the use of technology in MLB. Rockies fans are familiar with the Root Sports "Ford Strike Zone"; that box they put on the screen after borderline pitches that shows where the ball crossed the plate, indicating whether it was a ball or a strike. I don't know how accurate Root's graphic is, but with Pitchf/x data we have the technology to almost perfectly measure where the ball crosses the plate, and thus perfectly administer ball and strike calls. Right now we only use that data for after-the-fact analysis. But would it really be that big of a leap to use it for real-time ball and strike calls? The question is: Is this a good idea?
