To me, these guys probably aren't "good enough" to make the 25 man roster, but they are out of options.
Marrero
Swihart
Brentz
Hembree
The questions are:
1) Are they good enough to make some other team's 25 man roster? (If yes, then a trade is possible to those teams.)
2) Do we makes sure they are placed on the 25 man roster to keep system depth by keeping similar or better players in AAA until needed?
Assuming all players out of options make the 25 man roster, this is what it would look like (before any acquisitions):
I'll leave Pedey & ERod off the roster and concentrate on the opening day 25 man roster...
C- Vaz
1B- HRam
2B- Hernandez (Pedey after DL?)
3B- Devers
SS- Bogaerts
LF- Beni
CF- JBJ
RF- Betts
Bench- Leon, Holt, Marrero, Brentz
SP- Sale, Price, Pom. Porcello, Wright (Erod after DL)
RP- Kimbrel, Smith, Kelly, Barnes, Maddox, Scott, Hembree
Players in AAA because of Marrero, Swihart, Brentz and Hembree:
Lin is probably better than Holt and Marrero. When Pedey returns, Holt or Hernandez may be forced down, so we can keep Marrero.
Travis might be a better option than Swihart or Marrero/Holt.
Workman is better than Hembree, IMO. Taylor or Johnson might be better chocies as well. When Thorburg returns, Scott or Maddox might be forced to AAA to keep Hembree on the roster.
None of these choice are earth-shattering. If we have to trade or DFA Holt, Marrero, Swihart, Brentz or Hembree, nobody will lose any sleep, but what else is there to talk about at this point in the off season?
