I'm hesitant to try to guess most of NY's plans this winter because there are a lot of different directions they can go, literally no one saw Bader for Montgomery or anything like that coming a few months ago before it happened. One thing I can do though is go through NY's top position player prospects on the 40 man as well as the best others at AA or above, and try to guess when they might be ready to contribute if needed:
--------------------
Now/2023:
Oswaldo Cabrera: I think we all saw enough of him already to see that he has a lot of skills and is at the least a Zobrist/Marwin type who is ready to get a shot now.
Oswald Peraza: He was ready to get a shot in the middle of 2022, ugh.
Anthony Volpe: 1st round pick in 2019 (#30 overall) out of high school, still very young, 21, 22 on April 28. He spent most of the year in AA (.820 OPS in 497 ABs) and went to AAA on 9/2 (.717 OPS in 99 PAs). He was the first combined 20 HR/50 SB minor league player this year since Fangraphs started tracking that in 2006. He is a top 5-10 MLB prospect currently on most lists and will get every shot in spring training and I'm guessing will be ready by June or July if not earlier.
--------------------
2024:
Jasson Dominguez: He is still 19, 20 in February. He started 2022 in low A, was promoted to high A on June 22. He only stayed there for 40 games/184 PAs (.906 OPS) and went to AA for the final week of their regular season and the playoffs (10 games total), he struggled at first but hit three HRs in the final two playoff games. I would guess he will start 2023 in AA and be ready sometime in 2024 when he is 21.
Austin Wells: NY's 2020 1st round pick out of college, he turns 24 next July. 20 HRs and 65 RBIs in 336 ABs this year across three levels and a .897 OPS in AA, his bat is very likely to play so it's a question of whether he can stick at C or will have to move to 1B or DH. The bat should be ready sometime in 2024.
Everson Pereira: He was born the same month as Volpe (April 2001, yes we are all ancient) and is now entering his second year on the 40 man already, clearly NY likes him. He was incredible in 2021 (20 HRs in 188 ABs!) but had a streakier 2022, but he got to AA and had a .845 OPS in 123 PAs there. Interestingly (maybe only to me), that is the second straight season that Pereira has outhit Volpe as teammates, but Volpe is ranked much higher despite them being almost the exact same age. I don't think it's a defensive thing either, I think both are regarded as solid but not incredible at SS/CF respectively. Anyway, he will likely be ready in 2024 but could be pushed up earlier because he is on the 40 man already.
--------------------
Trey Sweeney and Spencer Jones (the 2021 and 2022 first round picks) will hopefully be right behind those six, four first round picks and four Latino international signings, that is a lot of young talent to hopefully have infused over the next few years. All eight of those guys look great as of right now, both prospect pedigree and results, and all could hit NY in the next three seasons as impact players if they keep it going and are not traded before then. Cabrera had enough ABs to graduate but the other seven are all top 100 guys or close, I have seen all seven on at least one list (even Spencer Jones who was just drafted in June but looked incredible in low A).
