Another look at Park factors - By Division
Posted: Mon Jan 26, 2009 9:26 pm
Aaron Gleeman has a new article up at Rotoworld which he has "chosen to focus on Baseball-Reference.com's three-year park factors (unless a specific ballpark hasn't been around that long). A park factor above 100 means hitter friendly and a park factor below 100 means pitcher friendly."
I have taken the liberty of stacking his findings by division to look at how the park factors play out on a division basis. A couple of things surprised me ...
1.) Despite having the most pitcher friendly park by far, Petco, the NL West actually edged out the East and Central with the highest average hitter friendly park factor:
NL West (101)
COL 107
ARZ 107
SFG 102
LAD 100
SDP 89
NL Central (100.5)
CHC 106
CIN 104
MIL 100
HOU 99
STL 99
PIT 95
NL East (100.5)
PHI 103
WAS 101
FLA 99
ATL 99
NYM unk
I expect, based on everything I have read about Citifield, it will be a sub-100 park ...
2.) The difference between the AL East and the West is much larger then I would have guessed:
AL East (103.5) - bombs away
BOS 108
BAL 103
TBR 103
TOR 103
NYY unk
AL Central (100) - allegedly neutral overall
CWS 105
CLE 103
DET 102
KCR 97
MIN 93
AL West (98.5) - favors pitchers overall
LAA 103
TEX 101
SEA 96
OAK 93
