Todd, Congrats on your back to back NL Auction wins. My question is what constitutes a line drive? Is there is definition what a line drive is? In the last 5 years, Juan Pierre's line drive percentage is higher than Albert Pujols'. This is according to the Baseball Forecaster. Now, I've watched plenty of at bats from both players and I have a hard time seeing how that can be true. Albert hits the ball very hard. Juan, not so much. Thanks for leaving me a little something last year Lindy. You were right there in that league as well for a good portion of the season, but it is perfectly understandable if the bulk of your attention was elsewhere
One of the caveats working with ground ball, line drive and fly ball data is the judgment is, as you suggest, subjective. It has always been a little dangerous to extrapolate data from one source to another, especially minor league data.
I am somewhat familiar with the manner Baseball Info Solutions does it. There is a good chance this has changed, especially with the improvement in technology, but each staff member was trained on what to consider a GB, FB and LD so there should be some level of consistency.
I also know they are refining the data collection to label hits as not just grounder or fly ball, but hard hit, medium hit and softly hit. So there is some delineation available. It is just that this increased information is not available for "free". And finally, I also believe BIS is using a 4th type of hit, cutely termed a FLYNER - combo line drive and fly ball. But again, you have to pay for this, it is not readily available.
I'm just guessing Pierre has a few more soft line drives than Pujols, while Pujols has a few more hard hit fly balls than Pierre

I look at this data like I look at park effects -- big picture. I don't care if Petco reduced homers by 15% or 25%, it is hard to hit a HR in Petco.
I don't care if Webb's throws 47% GBs or 54%. The predominant type of hit against him is a grounder.
