In spite of their ages, Bonds, Aurillia, and Kent
all had their best years by far with PacBell as their home ballpark.
Since I haven’t seen a ballpark adjustment factor for artificially
increased levels of testosterone, I’m going to leave that out of my
analysis. Because the data doesn’t exist and American jurisprudence
doesn’t allow specific conclusions without confession or trial,
we’ll have to assume that every team has an equal amount of equally
enhanced humanoids.
Snow, who has had an erratic career, had nearly
identical seasons in 1999 and 2000. He wasn’t helped by the move like
the others, but he clearly wasn’t hurt either. Chart 2 shows hitters
who were Giants in intermission and others who were regulars in other
home ballparks and PacBell in recent seasons.
