1. Who will DD get for a closer this year or will he just go with the pen as it is currently configured and bring up one or two minor leaguers to fill it out?
I think DD will acquire one decent to significant RP'er, who may or may not have much closer experience. It probably will be via trade (Chavis/Swihart?).
2. Will Pedey's knee be in good enough shape to allow him to play a significant amount of the season at 2nd base? If not, then will DD make a move?
We'll never know about Pedey. He could go down at any minute. I don't think we make a deal, until we see how Nunez looks and if Holt is still strong. At worst, we make a similar trade as the Kinsler one in July.
3. How will the catching situation be resolved? Pretty much it is assumed we will only keep 2 on the roster, but how will that be decided?
I don't see this as an issue. I think Vaz is the starter. Leon is Sale's caddy. He probably should be Price's caddy, too. That would make Vaz the 60% starter with Leon getting 40%. Maybe Vaz catches half Price's starts making him the 70% starter.
Swihart comes to ST'ing maybe needing to win a job as a utility player with the added bonus of being able to catch when needed, or if we PH for 2 catchers in a game. The 25th slot goes to Swihart, Lin or Chavis if a 1Bman is hurt).
I think Vaz will come closer to his 2017 numbers on offense than his 2018 ones, but I'm fine with our catchers' performance of 2018, despite the poor offense all around..
