    Getting closer...a lot closer...to being able to accurately measure defense...

    Sportvision's new tool is FIELDf/x, which should open up the fielding toolbox in the same way that PITCHf/x created a deeper understanding of pitching. Instead of simply measuring a player's output (e.g., where he caught the ball), FIELDf/x should allow for a more accurate measure of a player's fielding process. Who gets the best jumps on fly balls? Which team does the best job of defensive positioning, getting its players in the right place to make plays before a ball's even hit? What's the optimal shift to employ against a particular slugger? FIELDf/x won't provide all the answers, but if the data compiled by the project gets released to the public, it will bring researchers much closer to them.

    Rybarczyk believes that even as we cut our measured plays from a few hundred (per player) to something less than 100 per season, what we lose in sample size we'll gain in sample importance, and that the one-season numbers will give us a more accurate appraisal than we've got now. (so that you don't need three years, but one to measure a player's defense using statistics.)

    Not surprising. There's a long way to go in refining fielding stats and this seems like a nice advance -- weeding out those plays that no fielder makes (beyond possibly committing an error on the ball after it's landed), and then, I would say, devaluing those routine plays that all make (thinking here especially of OF play). Basically, understanding the characteristics of each ball in play much better than assigning it a zone.
