I wrote a longer article on AN about the effects of thin air on pitch movement and how it might affect different types of hitters. I specifically looked at what might play a role in Carlos Gonzalez' strong home and away splits and came up with some pretty surprising results.
It is definitely nothing Earth-shattering, but might make for an interesting read.
Bellow is one chart from the story, if you want to read the whole article, please do so here.
The washed out ones are the movement locations of the same pitches on the sea level. The bigger the distance between the foreground and a washout mark, the bigger is the "Coors effect" on that specific pitch.
