Perhaps, but there were a number of reports from the minors when he was at AA/A+ that he was hitting 96-98 in the 6th inning or later. When you are getting yanked back and forth between AAA and the majors, and the pen and the rotation, I don't know how you can measure consistency. You have to have a consistent role first. Sometimes when these guys get called up it's on short notice and they are on really early flights, don't get much sleep, are anxious about pitching in the majors, etc., which can all affect performance. Speaking of pitcher-friendly parks, not only does Bumgarner have a pitcher-friendly home park he also pitches many road games in other pitcher-friendly road parks (San Diego and Los Angeles) due to the unbalanced schedule. He also pitches a lot of road games in hitter-friendly parks (Colorado, Arizona), so that may balance out.
