Arizona under 87 +100
Oakland over 73.5 -102
for similar reasons
Arizona won a lot more than they should have based on runs scored/runs allowed; Oakland won less
Arizona scored more than they should have based on avg/obp/slg; Oakland scored less
Arizona added talent, making them look better, but one pitcher isn't everything, and they actually overpaid in terms on talent because his contract was so cheap; Oakland is definitely rebuilding, but they only gave up a couple players, and still got something in return
Arizona had few injuries, Oakland a lot
NL West is most competitive division, Seattle and Texas were both outscored by their opponents last year (and Seattle under 84 is a good bet too)
