For 2022 I want to strengthen the starting pitching. The rotation may improve naturally with Chris Sale back to full health and Garrett Whitlock making a successful transition to the rotation, but you may be losing E-Rod as well. First thing I do is offer Erod a qualifying offer, if he turns it down you can effectively target another starting pitcher without losing a draft pick. There's no silver bullet in FA, everyone comes with a level of risk vs. reward. Scherzer is still elite but old, Syndergaard could be the steal of the century but he's coming off of TJ.
So my rotation is going to look something like this.
Sale
Erod/Gausman/Scherzer/Syndergard
Eovaldi
Pivetta
Whitlock.
Next I'm signing a position player that can shore up the defense and elongate a lineup that's too top heavy. I have Carlos Correra in mind, plug him at 2nd with the plan on moving him to SS when Xander walks. Pick up the option on Vazquez and plug Kike into CF.
Your lineup becomes
Kike CF
Correra 2B
Devers 3B
Bogaerts SS
JDM DH
Verdugo LF
Renfroe RF
Dalbec 1B
Vasquez C
If you JDM does not return you can sign Schwarber, which gives you another lefty. Of course you could just sign Schwarber anyways and plug him in LF and move Kike to 2nd.
