The pennant now seems highly probable for us, but not yet a certainty. Too many big games ahead before we clinch. It does seem more cogent to talk about the playoff roster in detail with just a few weeks left. Moon has done his usual detailed and fact backed attempt at a list and I mostly agree with him. I do think our experienced guys who DD brought in this year have helped us a great deal to get where we are. They tend to be former excellent defensive and offensive players who haven't lost that much even though they are in their 30's, some late 30's. Their experience shows in good at bats, base running and awareness in the game. The FO should make decisions dispassionately, based on who gives us the best chance of winning going forward. It may be hard for them to avoid the favorite son syndrome or worrying about pissing off a guy you definitely want back next year. They need to do their job and I think they will.
I now there are arguments for 11 or 12 pitchers and that impacts what field players we can keep on the roster. I subscribe to the idea of 11 pitchers.
My approach is to look at the roster from the depth point of view as i list below:
Outfield: No mystery there but no Holt)
Betts (Right), JDM, Swihart
JBJ ©, Beni (Fenway), Betts (away)
Beni (Left), JDM (Fenway), Swihart
Infield: Some questions
Moreland (1st) right handed pitching, Pearse left handed pitching, Swihart, Holt
Kinsler (2nd), Phillips (if available), Holt (Pedroia is just not prepared enough to make it in my opinion)
Bogaerts (SS), Phillips (if available), Holt
Phillips (3rd) if available, Nunez (close second), Devers (maybe for left handed bat)
Catcher: Hard discussion here in my view
Leon, excellent defense, familiarity with pitchers, ability to handle knuckle ball, but very weak hitter
Vaz, solid catcher, weak hitter but better than Leon
Swihart, decent catcher, lacks familiarity with staff, better hitter than the other two.
DH:
JDM, best in league, Pearse, Swihart, Holt
You might have noticed I have listed 15 field players but only 14 can make it. Who falls out? A catcher, a third baseman, or do we sustain an injury in the last few weeks?
Pitchers: (Starters)
Sale
Price
E-Rod
Porcello
Pitchers: (Relief role)
Kimbrel
Brasier
Barnes
Kelly
Wright (Long Relief)
Eovaldi (Long Relief)
Who is #11? Need a lefty (Pom, Johnson or Poyner), Include Hembee and forget about a lefty. Tough choice. There are others righties, such as Workman who might be chosen in front of Hembree. Personally, neither Pom or Johnson seem reliable so is it Poyner?
I certaintly don't have all the answers but looking at the choices with depth in mind clarifies what is at stake.
