Offense is up, but Nashville is a pitcher's park, especially relative to the rest of the PCL parks. From '06-'08 it was the 9th-most suppressed run environment in the minors. It may have ticked up a little since then, but it definitely isn't a bandbox by any stretch. Green's MLE, adjusted for league factors (I'm not sure if it's from '09 or '10) is currently .264/.329/.461. If he's even close to that, that's an above average third baseman almost every year. If you platoon the two, Green's MLE v RHP is .288/.355/.523 (!!!). I don't totally buy the argument that because he's never faced big league pitching, he'd struggle. It's unlikely he'd maintain his 935 AAA OPS, but there's a good chance he'd be somewhere in the neighborhood of his MLE OPS of 790. And even if he's only able to manage a 700 OPS, well, that's still better than Casey right now. All that said, I have severe doubts that the Brewers would consider replacing McGehee with Green, or even platooning the two. It doesn't send a good message to the clubhouse that the Brewers will give up on a guy who had a .290 career batting average for the first ~1100 AB of his career after 240 AB of this year. And he's not a 605 OPS player. He should be better offensively the rest of the way. Still inadequate defensively and slower than a geriatric snail, but better with the bat.
