Well as far as chances of winning are concerned....I think it is pretty clear that WMB does give us a better chance to win than Youk.
Of the outfielders we have at our disposal today, if Nava can play today, Nava gives us a better chance to win, particularly if we are talking about Nava vs d-mac in LF. If the choice is Kalish vs Sweeney in RF while I like Sweeney, the Sox might need more pop in the lineup than they have right now. They are not exactly the same type of players at least to me. Given the way things have gone, I think Kalish would be worth a shot. Looks to me that at least at this point, Pods should play Center.
I think the next two options are really iffy at this point. Iggy and Aviles are clearly not the same kind of player. If the Sox see this stretch of tough, well pitched low scoring games continuing for some period (which could be true this month) then Iggy would likely help this team have a better chance to win than Aviles. It is in these low scoring games where a missed play or an error or a great defensive play for that matter can really make a big difference that might make it worth a shot....particularly since we are tossing so many guys into the outfield. Mike might be just fine in the outfield if you want his bat and Iggy's glove in the lineup. Mike is not really tearing the cover off the ball right now but I could still maybe see him play a few games in the outfield particularly while still waiting for Ells and CC to come back. So maybe....MAYBE there is a chance for Iggy to contribute.
Lavarnway vs Salty....I would say at this point, even with all of the grief that I have given Salty, I think Salty deserves to play out his current approach to plate appearances a little farther before deciding to pull the plug and do something like bring up Lavs.
In the first place, everybody has been saying that at least today, Lavs is not a defensive upgrade over Salty. I don't know if he is or not. If he was then that would make for a completely different story for me. In truth, since that disaster of a game for Salty where Cook was injured and Salty looked about as terrible as could be, Salty has been better in the field. There are still things he does very poorly and I have to think some additional really ugly defensive plays are always right around the corner with Salty. But again, nobody is saying that Lavs is better at this point.
As for handling pitchers, well I guess Salty is not everybody's favorite catcher. However can we really say with any surety that a young kid that would be a new guy behind the plate would really instill confidence in the pitchers at this point?
Now the last week to ten days it has looked like pitchers are starting to adjust to Salty's new approach toward plate appearances and Salty has not been making contact as much. If they have Salty's number at this point and this is what we are going to have for the remainder of the year, then I would say yes to bringing up and playing Lavs. I would be willing to give this a couple weeks before giving up, not because of anything Salty did or did not do last year. I would do it because Salty has opened the door to the possibility that he could become a real HR threat. That is a classic offensive approach for a catcher. You really don't want them on the base paths. A catcher with a low BA but serious power numbers is an asset. My God I cannot believe I am talking about Salty in terms of being an asset but again without any evidence that Lavs would be a defensive upgrade or a preference for the pitchers, I would continue to go with Salty for now and spot Shop against the LH pitchers.
As I said in a different post, to me there is an element to this that also makes getting more fresh blood in the lineup worth a try. We do seem to get a more cohesive baseball effort with fewer of the "old guard" vets that have guaranteed contracts and tend to play the game the way they want to play it individually when they are in the lineup. That is likely worth something in these close, well pitched games.
Clearly we would not be talking about any of this if we were not struggling to win games.
