Since it has come up in other threads, I think this might be the thread for discussing possible winter additions to the 40-man roster. These decisions will be driven by (among other things) Rule 5 eligibility, and possibility also eligibility for minor-league free agency.
There are a bunch of guys who technically will be eligible for the Rule 5 draft - at some point, I (or somebody else) can post a list... but the issue, of course, is which of these guys would actually be at risk of being drafted, and of those, which of them do we actually care about?
I'm uncertain, actually, about how to evaluate minor-league free agency. The standard contract expires after seven seasons (e.g., "six-year" minor league free agents actually have to have played for seven seasons - go figure). But what I don't know is whether the cancelled 2020 seasons "count" as one of those seven seasons, or whether clubs get an extra year of control because there were no "championship seasons" in the minors in 2020 for these guys to play in.
The list of eligibles for minor-league free agency will consist mostly of older guys in the upper minors, who were signed by the Phillies as either insurance, or as filler for those rosters. Assuming that the "lost" 2020 counts, there are a few of our own draftees/amateur signees, though, who become eligible for free agency after the World Series, if they're not added to the 40-man roster. A list (may not be complete):
Daniel Brito
Edgar Cabral
Arquimedes Gamboa
Nick Fanti
Mauricio Llovera
Cornelius Randolph
Scott Kingery is also in this category (he's played in seven seasons), but his contract is guaranteed, so he may not be eligible (and the Phils may be obliged to add him to the 40-man roster because of that contract?).
If the "lost" 2020 seasons don't count, then the only player on the above list who would still be eligible for minor league free agency is Llovera - he played (in the majors) in 2020.
