My personal opinion is that they are somewhere 10-15.
AAA - Aside from Bello, the pitchers that have made it to BOS haven't been very successful (Crawford, Winckowski). Mata has potential, but is probably just a reliever. Rafaela is most likely the only impact bat. I'm not sold on Duran, Hamilton or Abreu.
AA - Lots of hitters to watch (Kavadas, Scott, Lugo, Abreu), but the only guy with a clear carrying MLB tool is Yorke. Unfortunately, he had a terrible season last year and has an injury history. The current projected pitchers for AA are rough. This is the 2020 draft class that was restricted to only 4 rounds for the Sox. Maybe it'd look better if there was a normal draft that year? IDK.
A+/A - The strength of the organization with Bleis, Mayer, Hickey, Romero, Bonaci, Paulino, Blaze, Roman, Perales, ERC, Winkelman. Most of these guys are just years away. The only guy who could make a short term impact would be Mayer. I'm not sure anyone else would be in BOS before late 2025.
FCL/DSL - These guys are really far away. Who knows? Includes Brannon, Coffey, Freili, Alcantara, Fraymi, Yoeilin.
It is a very heavy, bat first organization. Is that a guiding principal for Chaim? We've seen lots of high ranked prospects go down with arm injuries recently. Some high drafted arms can't even get out of AA. There's just a lot of variance. Maybe it's just circumstance because other organizations have gone heavy with arms (Cleveland, Angels)? The Dodgers only drafted one pitcher in the first 10 rounds last year and they are one of the best organizations in baseball year in and year out (only 4 pitchers taken in all 20 rounds).
