This is an improvement over looking at regular BABIP and LD%, though there will no doubt be more improvements in the future.

I think the important point of the article is that LD% is a major component in predicting BABIP. If you use BABIP, or you rely on someone who makes projections which assume BABIP regression (i.e. everyone!) this could be very significant.

i dont. i shouldnt say i dont completely. if i need help deciding between two players i may delve into some sabermetrics, but generally i do not.

Thehardballtimes put out an article in early december predicting xBAPIP with more varialbles than LD% and found a pretty good correlation. Speed (beating out GB's), LD% (still used), and power (GB's finding holes) among other factors were used. It could be said that the fangraphs article was late to the party...

thats what i never understood about BABIP. speed is obviously a factor in beating out infield hits (i remember a few years ago, willy-t had like 50 infield hits) that to not include it in the statistic just makes it too flawed in my eyes.

That's why the thehardballtimes included it in their new stat (predicting xBAPIP).
