I suspect there's only a limited correlation, b/c rankings are generally based on "name" prospects (high draft picks and bonus babies). Unknown prospects who fly up a farm system are often recognized only when they're on the verge of the majors, then they stop counting for rankings - so a high draft pick who slowly moves up the ladder helps rankings more than an obscure prospect who flies up the ladder, even though the latter is more likely to be a star.
MLB site has the top prospects of each team for each year.. not the system rankings that I can find.
Like here is the Phillies 2011 top 10
https://www.mlb.com/prospects/2011/phillies/24
I suspect the Phillies system wasn't highly ranked in 2011, despite that Brown was the #4 overall prospect and Jon Singleton was #30. (Kyle Drabek was #12, but I think he was a Blue Jay by then.) And the top 10 listed there produced no stars and probably single digit cumulative WAR. So if they were ranked low, that was accurate.
Marsh has a 3.2 WAR.
They might have hoped Hays would add more than just a platoon bat if he could get back to his previous form (2.5 WAR last year) but obviously he was not going to add that much production in two months. They also had to know it was a long shot that he'd truly thrive against RHP.
Really, it was probably just as likely Marsh would come back around to his 2023 numbers against LHP, given the chance, as Hays would do the same against RHP.
And Rojas has 0.5 WAR in just 264 PAs. He's almost certainly played like a 2.0 WAR OF or better since his early season struggles, even if he's not hitting or looking like a Gold Glover the way he was last year (when he put up a 2.5 WAR with just 164 PAs).
Posted in the wrong thread somehow.
Completely unsubstantiated claim. Farm system rankings are likely going to act similar to top 100 or other rankings in the sense they are going to be driven by the best prospects in baseball and they are going to be tiered. There will obviously be shallow systems driven by very top prospects that are dependent on the success of that player (we know top prospects do fail), but I think you are going to see tiered success with a larger gap of success between 1 and 5 then between 5 and 10 or even 15. There is probably a drop at the end, but also these are just minor league rankings so a team like say the current Braves with a young MLB core is not going to have their success determined by minor league rankings as much as a team in a rebuild where that will be the core.
The only caveat is there are no high school number ones competing for prospect lists any more. But it is always good to see the previous international class well represented. And Aroon Escobar has been really under the radar with injuries. He seemed to show much better command of the strike zone this year when healthy along with the power and defense that we already knew about.
While some of those mentioned are decent prospects, next year's FCL team will probably have fewer top prospects. The big money guys (Arias, Mujica, Navas) have been hurt or had lesser years. The 17-year-olds playing well like Quinonez are less heralded (and maybe less toolsy than the top prospects). And some like Cardoza and Calderon are in their second DSL year already so in FCL they will be competing for prospect status with guys a year younger than them.
The guy that fell through the prospect list cracks is probably Alirio Ferrebus. While also repeating DSL he dominated and went to FCL and got hurt before he had enough playing time to make a list. And he could be in Clearwater next season so he'll have to compete with Tait for both playing time and prospect status.
It is also really hard to see if we have any pitching prospects. We are not spending much money on pitching and the best arm might be a guy like Pedro Peralta with no command at all now (see Matt's article about him on Phillies Minor Thoughts). Any 18-year-old arm could have a breakthrough of course. Just hard to count on it now.
