Could it be that the large foul ground in Oakland allows the corner outfielders to catch a higher percentage of flyballs, regardless of who is in CF?
Oakland's foul territory isn't really that wide in the outfield. But the infielders catch way more popups than do those of other teams, I'm sure.
Does the definition of "fly balls" in this study include infield popups?

I recall an old study by P Birnbaum which showed that the "reliever's ERA advantage", as a function of their role and not their talent, is about .2 runs.
What exactly is meant by a "function of their role"? Is it simply from the fact that relievers sometimes come into innings with one or two outs, while starters never do?
I mean, suppose we have three pitchers in one inning: each pitches 1/3 inning, and each yields a triple, and then gets a strikeout. The first two pitchers end up with an ERA of 27.00, the last one gets an ERA of 0.00, even though they all gave up the exact same sequence of events.
Is that what the .2 difference comes from?
