YES! From 2 to maybe 10 years ago!
Since Lester in 2005, Papelbon in 2006 and Buch in 2007, we've had very little to get excited about. The few we had were traded away (Masterson, Kelly, Espinoza, Kopech), got hurt (Groome & others), fizzled out (Bowden, Ranaudo, Owens, Johnson, DHern) or 2 or 3 of the above.
If you want to count Masterson or Bard (2008-2009) or Barnes (2012-2013,) fine, but since then, we've only seen Houck and the Rule 5 guy, Whitlock, make an impact. One can say Whitlock was not a product of our farm, since he never pitched on the farm, except for rehabs.
Whitlock, Houck and Bello have graduated from 2021-2022. That's the best we've seen in a very long time, but the 8 years prior to that were god-awful.
Here is a list of those 8 years top ranked pitching prospects all together:
(Highest ranking on soxprospects.com from 2013, when Barnes graduated to 2020, when Houck was promoted.)
1 ERod (acquired and not really a product of our farm- only pitched 85 IP in Sox minors before call-up))
2 Owens
2 Espinoza (traded)
2 DHern
3 Webster (acquired)
5 Kopech (traded)
5 Ruby de la Rosa (acquired)
6 Ranaudo
6 Johnson
9 T Ball
9 Workman
9 T Lakins
10 Beeks (traded)
11 Drake Britton
13 Logan Allen (traded)
One can argue, looking at the results of the list above, and not counting ERod, Webster & RDLR, our current pitching prospect list is pretty close to as good, than that whole 8 year period combined turned out to be. If we could count Bello, it would be even closer, IMO.
