a new version of the BIPChart Windows application I wrote a couple years ago for my own research has been updated with data from 2003 through 2006. The software displays the percentages and directionality of ground balls, fly balls, line drives, and pop ups for both hitters and pitchers for each year with hitters broken down by side of the plate they hit from (switch hitters getting two entries) and pitchers shown against both left and right handed hitters.
Here's an example, taken from Marc Normandin's recent Juan Pierre Player Profile (2004/2005/2006):
Access to these charts led Normandin to the following insight:
If I had any idea how to take snapshots of Red Sox players' charts, I'd do it here and now.
There was a significant moving away from his slapping the ball to the third base side in 2005, with a slight return in 2006. It's tough to say exactly how things shaped up, especially considering he only had six additional ground ball outs than he had in 2004, but the trend towards pull hitter on the ground is one that will eventually hurt Pierre’s already dwindling value.
Whatever caused the fluctuation-–and I'd love to hear reader feedback on the matter--was reduced somewhat in 2006, when Pierre's line drives and infield flies both dropped by a few percentage points while his FB% recovered. This was not enough to make him productive, and although he was below his expected BABIP, I'm certainly not confident it will remedy itself in 2007. Whereas his groundball tendencies earlier in his career appear to have helped him out significantly in the BABIP department, Pierre is now going to be 29 years of age, and while not old, he's certainly not getting any younger.
Have at it.
EDIT: Also, I meant to start this topic in the General MLB Forum. Sorry, feel free to move it.
