The "holes" in our data is as follows. I suggest that this post gets
updated going forward.

Hitting:
SB - 1876 to 1885
CS - 1876 to 1919
IBB - 1871 to 1954
HBP - 1871 to 1883
GIDP - 1871 to 1932
RBOE - all years
SH - 1871 to 1894
SF - 1871 to 1953
(though I realize that the way the SH and SF rules and recording
practices were at the time that it might not even be possible to
separate things)

Pitching:
for any years where it was recorded:
pitch counts, balls, strikes

for 1871 to 1875:
IBB, WP, HBP, BK, BFP, GF, R

for all years:
RBOE, 2B, 3B, SB, CS, CI, Pickoffs

IBB - through to 1954
HBP - maybe through 1883 (DB shows zero where it should probably be
null from 1876-1883)
BK - maybe through 1880 (DB shows zero where it may or may not be
null from 1876-1880)


Fielding:
for any years where it was recorded:
"balls in zone"

for 1871 to 1875 (for catchers):
PB

for all years (for catchers):
SB, CS, CI, Pickoffs

for all years through 1999 (but not for pitchers):
GS, InnOuts

for all years through 1995:
Splitting OF data into LF/CF/RF

Note: design change needs to occur to show games played by OF, as
well as by any position. This has been discussed with the
APPEARANCES table.
