GB% by Base State

An interesting question raised at Fangraph's Q&A: Does GB% go up with a runner on first?

I queried retrosheet event files and sorted their recorded batted ball types by Base State and found the answer is: Apparently not.

BASE_STATE	GB%	FB%	LD%	PU%*
0	44.9	36.9	18.1	7.8
1	43.7	37.5	18.8	7.8
2	46.3	35.8	17.8	7.7
3	44.7	37.2	18	8
4	45.3	36.9	17.8	8
5	44.9	37.2	17.9	7.9
6	46.1	36.6	17.3	7.9
7	44.2	37.9	17.9	8.5

2002-2011, includes post-season data. Pop-ups are included in FB%, all bunts are excluded. 

I expanded on this table in a full article at BTB here:
