big win for the sox. Sale is great and has been great for 5 years. last 5 years has been an all star each year. finished top 6 in the cy young award race.
giving up moncada hurts, but who knows if he will ever hit the major league curve ball? (30% K rate, ouch.)
kopech might be great, might be a reliever, might be nothing. really hard to judge from AA.
diaz and basabe are lottery tickets, toss in players.
the sox look good for the next 3-4 years. lots of young talent and all signed.
As of now, the top prospects (per Soxprospects) left in the Sox system are:
A lot thinner than it was, but there are still a few good prospects. And for me, the point of the minor league has always been to provide talent for the major league club - either through promoting good talent or enabling trades for it.
I did not include Benentendi or Hernandez since they are already in Boston.
