Maddux is also nearly a run worse at home, and he is not the same pitcher he used to be. Ohka is also nearly a run better at home than the road.
Maddux last 2 years on road vs Montreal, 17 innings, 19 hits and 10 earned runs. Ohka last 2 years at home vs. Atlanta, 18 innings, 28 hits (ugh), 8 earned runs. I like the price on the dog here.
