With our outfield in question for a while offensively, I'm curious what would happen if Valentine decided to take a chance and go full-bore after defensive upgrades.
Three spots I can think of where you could sacrifice O for D and get quite a boost to your run prevention if that's the way you decide to go.
First obviously, is shortstop. Putting Jose Iglesias at short could pay off even if he doesn't hit much, if he makes the lives of his pitchers a few runs easier in any given game. If you believe that defense can have a large impact on the game and can provide as many WAR or more as any bat we're likely to get at short, which is a very reasonable assumption. then it's time to go with Iglesias.
The second, less obvious one is centerfield. I got nothing against Ellsbury, but the most lavish your praise can get for his defense in center is "Yeah, he good enough." He's not a liability as a defensive centerfielder, In fact he's an outright competent defensive centerfielder. What he isn't, is a great defensive centerfielder.
Enter Che-Hsuan Lin. Lin won't hit for much. Offensively he's pretty much a slap hitter. But as a defensive centerfielder I've never seen a guy who can cover ground like this guy can, and I'm including Coco Crisp in that. That and he has a plus arm which we haven't had in our outfields in forever. His speed is a match for Jacoby's and he takes far better reads on the ball off the bat. He's a defensive superstar, and if he could hit .250 and get on base OK, with his speed, he's someone's starting centerfielder. Why not ours? i'm sure the indispensable asset that is Ryan Sweeney can take a backseat to a guy who actually does something at an elite level. And I think the experiment would easily be worth sitting Cody Ross for as well.
If we need to prevent some runs this year because the staff is questionable, would starting Lin at centerfield and moving Ellsbury to right really be a terrible move? Crawford in left, Lin in center, Ells in right, and you have the smallest outfield gaps in major league baseball. Good luck getting anything but an absolutely blistered liner down on the outfield grass. And if you combine that with Iglesias and Pedroia at short and second respectively, and that starts to be a potential league leading defense.
Finally? Catcher. But here we have a problem. Shoppach is just a grass-is-greener guy. As a defensive catcher all he has going for him is better receiving hands. Much, much, much better receiving hands mind, but still, it's his only definite asset over Salty. This is a situation where the guy really needs to hit at least a little before you can let him play his glove in the field. Salty is a bigger upgrade over Shoppach offensively than Shoppach is over Salty defensively.
If you want to go D here you really need a catch and throw guy. A real one, not just a guy who is considered a defensive catcher because he's not an offensive catcher and you don't want to default to calling your GM an outright idiot. Until then I guess it's a question of who you trust better to improve. At this point, at least in my mind, it's Salty. Neither one is really going to complete the picture all that well as a run prevention unit though, which seems to be a thing the Sox FO doesn't obsess over when it comes to their catchers anyway.
As for a lineup?
Ellsbury, RF
Pedroia, 2B
Gonzalez, 1B
Youkilis, 3B
Ortiz, DH
Salty*, C
Crawford, LF
Lin, CF
Iglesias, SS
Thoughts?
*Yeah, Salty 6th is a little high in the order for him but you need something between Ortiz and Crawford as both have large platoon weakinesses, and I'm deliberately risking 2 poor offensive performers to max the D, so some chances need to be taken with the lineup.
And actually, if Lin and Iglesias can make any contact at all, that bottom of the lineup might play up a bit. It isn't short on speed, and if Lin and Iglesias can make some situtaional contact, it might allow Valentine to play his "real baseball" down there where runs might not otherwise be created.
