This article in Grantland seriously kind of blew my mind.
To boil it down into a Reader's Digest summation for the elderly and stupid, it's essentially a system (as-yet-unnamed) developed for MLBAM that incorporates the video-capture technology, rapid data acquisition and radar (used for PITCH/fx and HIT/fx) into one "thing" -- that is, it "sees" with multiple cameras and radar and superimposes the results into one aggregate, accurate representation of what really occurred. It simultaneously records and analyzes the data "seen" in the multi-vector product. Here, check this out:
So what do we think then? By my estimation, this will at once change the way we look at the defensive capabilities of a player (both figuratively and literally) and render certain defensive stats (I'm looking at you, UZR) less useful for statistical analysis.
Each recorded game results in roughly 7 terabytes of data.
The system will be in-use at three ballparks this season (Miller Park, Target Field, and Citi Field) with plans to incorporate it at all 30 parks next year.
