Here is what I think is likely to happen:
1) Re-sign Suzuki at about $5M/one year
2) Re-sign Sanchez at about $5M/one year
3) Sign Asdrubal Cabrera about $8M per year/2 years
4) Trade Newcomb to the Diamondbacks for David Peralta.
Rotation at the start of the season will be: Folty, Gausman, Sanchez, Teheran and Fried
Cabrera will play 2-3 games a week. Mostly spelling Camargo, Swanson and Albies against righties.
Duvall will play against lefties, with either Peralta or Inciarte being given the day off.
Pen will have 4 righties from among Viz, Winkler, O'Day, Carle and Sobotka, and 4 lefties--Venters, Minter, Biddle and Freeman.
AA will keep a fair amount of powder dry for mid-season moves.
We will have a nice group of players in AAA to bring up as needed: Riley, Touki, Gohara, Soroka, Wright, Wilson. We can ease Gohara and Soroka back into things and limit their workload so they can come in an make a big contribution later in the season. You always need 8 or so starting pitchers to get through a major league season.
This the outline of what I see happening. Obviously the details could be different. There are alternatives to Peralta such as Marte or Piscotty we could trade for. Similarly we could sign Marwin Gonzalez or Eduardo Escobar instead of Asdrubal Cabrera. I do think the focus will be on left-handed or switch hitting hitters who do well against righties. Our team currently leans a bit right-handed including 2 switch hitters (Albies and Camargo) who hit better from the right side. We need to balance that out a bit.
I would add both Suzuki and Sanchez have made clear they would like to come back. If you can keep veterans like that on sub-market one-year deals it is foolish not to do so.
