Jason Parks of Baseball Prospectus has released his Mid-Season Top 50 Prospects List (subscription required).
There are two Blue Jays on the list, I'm sure you can guess who they are.
Aaron Sanchez is number 24 on the list, moving up from #32 on the pre-season listing. This is what Parks said about him:
Prospect Trajectory: Up; a healthy Sanchez has one of the highest upsides of any arm in the minors; potential to be top pitching prospect if everything clicks.
Major League ETA: 2015
Roberto Osuna gets the 43rd spot, he wasn't on the pre-season top 101 list.
Prospect Trajectory: Holding steady; was underrated on offseason list; Osuna is a mature arm despite being only 18 years old, and the production should keep him in his current prospect range; lack of projection and a high maintenance body could prevent him from jumping into the rarified air of the top tier of arms in the minors.
Major League ETA: 2016
There are some former Jays on the list too.
Noah Syndergaard is #23
Prospect Trajectory: Up; has the combination of size and stuff to continue to climb the prospect ranks; a strong second half could propel him into top 10 discussion this offseason.
Travis d'Arnaud #28:
Prospect Trajectory: Down; can't stay healthy; has dual threat potential at premium position; hard to project 2014 status because of current injury.
Jake Marisnick #40:
Prospect Trajectory: Up; when healthy, is a well rounded talent that can play up the middle and provide offensive value; lacks elite upside but could climb the list with a strong second half.
I'm a fan of Marisnick, but I'm thinking that Syndergaard is the one we are going to regret losing.
