Definitely randomness. I've peaked at the DBACKS as well. LA DODGERS 12-13 since Break and oddsmakers continue to throw out very large number to a pitcher who was favored at home a number of times and failed to succeed.
I have yet to touch this game, but feel the market sent this in the wrong direction. I will wait to see the lineup cards (because of the frequent lineup changes by the DBacks and the material disparity in their VORP) before entering a position, but as of now, at least risking a small play on them is in the cards.
