To give you an idea of how bad the Rox offense is, they are 28th in MLB in OPS and 29th in runs per game, and they play half their games in an historically inflated run environment.
But, also, they have played nine of their 19 road games so far in three of the top seven run-inflated ballparks this season (Rays, Phillies, and, believe it or not, Dodgers), plus four more at a run-neutral ballpark in SF. Only in Kansas City and San Diego have they played in the kind of depressed run environments they can point to and say, yeah, that's a big reason right there we haven't been scoring runs this season.
