BABIP/DER

[GotowarMissAgnes]

The only consistent rule with BABIP is that players who hit more line drives have higher BABIPs. So you are right that players who hit the ball hard generally have better BABIPs than those who hit a lot of grounders and fly balls. But that's really the only statistically significant factor that has been found (IIRC). I wish I had a link to a site that had information on line drive rate or a study that demonstrated this result, but I don't remember where I read that stuff.
