Interesting that Giles home and away splits for HR's are pretty even. From 2002-2004, [the first two years in Pitt], Giles hit 28 Hr's in 800 ab's at home, while hitting 30 hr's in 846 ab's on the road.
This last yr, he hit 6 hr's in 266 ab's at home. and 9 hr's in 279 ab's on the road.
If Petco was the sole reason for his drop off, you'd expect a larger discrepancy.
I think you are looking at it the wrong way.
~Road
30 HR / 846 AB = 0.035 HR/AB
9 HR / 279 AB = 0.032 HR/AB
Those rates stayed relatively the same. About an 8% decrease.
~Home
28 HR / 800 AB = 0.035 HR/AB
6 HR / 266 AB = 0.023 HR/AB
Now a 34% decrease. These results suggest Petco is the largest reason for any drop in home run rate.
