I'm in the stand pat stands. No to older FA signings- Encarnacion or Bats, etc.... will be extremely expensive and likely underperform their contracts by a wide margin.
Mookie CF
Pedroia 2B/DH
X SS
Hanley DH/1st
Shaw 1st/3rd/DH
JBJ CF
Benintendi LF
Moncada 3rd/2nd
Swihart C/LF/DH
Definitely spreads out the production but also keeps people fresher throughout the season using that DH spot to rotate rest a little and keep guys fresh. Brock Holt, Vazquez, etc... can still get plenty of PA's here too.
And oh crap... forgot about Sandoval*
*If I'm being honest I can see Pablo being in the slot to start the season where I put Moncada and if he's showing health and mobility and sporting an OPS around .775 you hold onto him or deal him to address a need
So I expect this will be a popular answer around here, and it seems reasonable. I have a few concerns, though.
First, while basically everyone is ticketing Moncada for third, he's yet to play a game there.
The word is that they're waiting until he masters second base before moving him elsewhere, and that might not necessarily be to third. Even though we all are collectively wishing to send Pablo to Mandyville, he is still technically under contract and likely to at least get a chance to win his old job back. Either way, presumably they wouldn't want Moncada learning on the job at the MLB level, so this might slow his ascent. Maybe not a lot, though.
Second, while Shaw's bat makes him a valuable third baseman, does it play at first? Maybe it does in this offensive environment - as I look it up, he's 9th in wRC+ among 1B, but 11th among 3B.
Third, I don't think the front office will hesitate to move Swihart in a deal for pitching (or offense!), which would mean starting Vazquez. They could bring in someone like Lucroy or Vogt, and they can probably use prospects from the Chavis/Dubon/Basabe tier to do so.
EDIT: I was going to suggest the Beltran idea. Yeah, he'll be forty, but that makes him more likely to sign a less-risky short-term deal. No, he can't field anymore, but who cares? Not sure I see a downside other than the fact that he's playing well enough that someone might actually offer him a multi-year deal.
