The Fangraphs list I mentioned above has now been posted, 21 of NY's 38 prospects are teenagers. Definitely worth reading through closely when you have time if you're a NY fan, but here is the summary at the bottom:
=========================
System Overview
Perhaps no team’s talent cup runneth over quite like the Yankees. Since 2015, they have had 11 players selected from their org in the Rule 5 draft and made countless trades sending away viable major leaguers who couldn’t crack their 40-man roster. As they’ve enacted this 40-man churn, the Yankees have specifically targeted players far away from the big leagues, guys who don’t have to be added to their crowded 40-man for several years.
Because more and more teams have placed value on certainty and player proximity to the majors, the Yankees have been able to flip a bunch of relievers in their mid-20s for young, high-variance players who have sizable upside if things click. Our prospect asset values put big numbers on 50 FV or higher guys, and the Yankees only have one of those, so they won’t rank highly in our farm system rankings. But they definitely have the most of the high ceiling, high-variance sorts, including a few who, as we point out in the scouting reports, could be Top 100 caliber by midseason, giving the Yankees a high likelihood of moving into the top half of systems during 2019, barring trades.
When we spoke with scouts who were excited about talent from the low levels of this system, we asked why their team hadn’t traded for one of those players. The answer? The Yankees won’t discuss them. Their 40-man crunch, big payroll, and talented major league roster have driven the youth movement at the lower levels. This is interesting to contrast with the Rays, who have one of baseball’s smallest payrolls, have stocked their big league team with pre-arbitration talent, and have a farm system clogged with prospects at Double- and Triple-A.
A few other teams have begun to experience a similar 40-man crunch (San Diego and Tampa Bay come to mind) but the Yankees have been employing this methodology for a few years now, and it has had a drastic impact on the shape of their farm system. This, combined with a strong international program and a willingness to acquire additional pool space in recent years, has helped lead to a whopping 58% of the players on this prospect list being teenagers. On average, this is the youngest farm system we’ve written up so far, with players in the 35+ FV or better tiers averaging 20.2 years old, two years younger than in most other systems.

Brandon Drury saga is a great example of why that strategy is necessary. Perfectly fine big leaguers are hard for the Yankees to roster right now. They have stars, who will need to be usurped by other players of similar caliber. 25-year-old relievers and utility infielders may be viable big leaguers, but they don’t often suddenly turn into stars. Some of these teenagers might.
