While i want to be cautious and not be over-optimistic in the pitching depth, I did look back a few years ago and looked at what the full season clubs had as pitchers. Reviewing 2021, all pitchers who were age appropriate or younger (I used less than or equal to these ages - 25 for AAA, 24 for AA, 23 for A+, and 22 for A) and had about 50 IP, and that list in 2021:
AAA - Bettinger, Ashby, Jankins. Small was called up but would have been on this list. Not bad, but meh as Ashby and Small were top prospects, Bettinger and Jankins were hopeful inning fillers (even at the time)
AA - none, although J. Bullock did get some innings.
A+ - Jarvis, Olson, Reifert, Castaneda, H. Chirino, and a couple of others, with Jarvis, Olson and Castaneda deemed realistic SP prospects at the time. So this was a solid team.
A - J. Geraldo, Vasalotti, M. Guerrero, J. Cruz and Brendan Murphy. Vasalotti caught a lot of attention as a very young pitcher who could stand out, and Murphy was a former high draft pick ('17 I think) who was trying to get healthy. But despite a lot of inning this group was uninspired but Vasalotti and Murphy were on prospect lists.
Now we have much more (using about 35 IP as those should get > 50 IP by year end barring injury or promotions)
AAA - Miz, Henderson and Rodriguez all as top 10-20 prospects (Miz/Logan as top pitching prospects for the team)
AA - Kuehner, Cornielle, Hunt, Wichrowski, and Crow (who is now in AAA)
A+ - Flores, Birchard, Hardin (now at AA), Aquino and most likely DeBerry will get 50 IP.
A - Hernandez, T. Smith, B. Rivera, Meccage, Torres, B. Johnson and possibly Dubanewicz and Dorchies will see some significant time as teenagers along with Hernandez, Meccage and Torres.
Quite a change in quantity of younger pitchers, most with good stats, and also more upside. So yes this is trending the right direction. Now few are looked at as top of the rotation talent (Miz or Henderson aside) and most are middle rotation or back end depth but can certainly improve their status with either another quality pitch, increased velocity (ie Hernandez, Hardin), or improve command (Meccage and the '24 HS pitchers). Will be interesting to see how we view the pitching depth in the system in a year or two.
Health, continued development and some good luck will really make a difference between "nice" depth vs true foundational depth that can augment the franchise for the next 5 years.
