True, but since we score more at home, we often get more PAs in the process, so, here is fair:
2003-2017
Home: 47,075 PAs
1,333 HRs 2.8%
202 3Bs 0.4%
2,932 2Bs 6.2%
7,478 1Bs 15.9%
4,937 BBs+HBPs 10.5%
HRs per AB: 3.2% (1333 in 41567)
Away: 48,036
1,486 HRs 3.1%
192 3Bs 0.4%
2,151 2Bs 4.5%
7,261 1Bs 15.1%
4,840 BBs+ HBPs 10.1%
HRs per AB: 3.6% (1486 in 43036)
Still, clearly more HRs Away than Home. Significantly more 2Bs at home and more singles and BBs at home.
