BIP Type Distribution

About a half a year ago, Dan Fox wrote a nice little program showing BIP type distributions from 2003 to 2004. You can search by individual players or different groups of batters (left handers, right handed power hitters, etc...). You can find the post with a link to the program HERE. Here's the program displaying Geoff jenkin's BIP distributions:

I dug it up after someone at questioned whether batters typically pull grounders. Here's what I found:

2003 - 2004, Groundballs
                 Pull     CF      Opp
Right Handers 38,382 12,828 10,320
Left Handers 6,195 20,894 8,472
44,577 33,722 18,792
45.9% 34.6% 19.4%

Twice as many groundballs are pulled than hit the opposite way. The odd thing about it is that lefties' groundballs are pretty evenly distributed. Let's look at what fielders fielders actually make plays on the grounders, according to data in this article:

2003 - 2005, Groundballs
GB     Bats     1B    2B    3B    SS    OF   
41034 L 0.22 0.31 0.06 0.15 0.17
54460 R 0.04 0.14 0.26 0.30 0.17

Hrmmm. This data has an extra year in it but has less total ground balls. Unfortunetely, Lost is on so I'm out of time! I'll have to update this another time.
