     Before you go screaming your head off about where Amed Rosario is in regards to this ranking....read my primer here first, then read what I have to write here. Appreciate the positives at the begining of each paragraph....but then also recognize the risk associated with the negatives that are still present. I must confess...I was extremely unfair to Amed Rosario last time we reviewed him when I gave him a ceiling of Troy Tulowitzski after just seeing him in Kingsport. While he may eventually get there, he's not THAT good.....yet. That said, Rosario is still possesses one of the strongest ceilings in the Mets system right now.

    Rosario has made some improvements on his swing by cutting down his swing length and reducing the severity of his leg kick. When combined with his already quick hands, the changes have given him the ability to turn on fastballs both inside the zone as well as keep up with premium velocity stuff up in the zone. While  Rosario has grown physically stronger year over year, the added strength is not translate into his swing. When taking batting practice next to the likes of Michael Conforto, you could HEAR the differences in the loudness of the contact each player was making. While Rosario was driving pitches in all directions, it just didn't sound like a powerful enough swing yet.

     Rosario's hitting approach has been improving as well. He has been able to cut down on his already reasonable K rate from 19% in 2013 to 18% in 2014. He seems to have a strong sense of the strike zone from top to bottom, never chasing pitches that are too or too low. However, he still struggles quite a bit with his K zone recognition from left to right, primarily on horizontal breaking pitches such as sliders and 11-5/10-4 curveballs. It's certainly not a problem that's particular to him as most 18 years olds have this problem,. He still has plenty of development time left to improve on this pitch recognition skills so the point here is that....again....he is no where close to a finished product and he still carries significant development risk.

     Lastly lets touch on the defense. Rosario is pretty solid this aspect of his game. Playing on a much higher quality Brooklyn field than in his past seasons, his hands looked softer, his fielding looked clean, and his reactions off the bat were pretty solid. He possesses enough arm strength to stick at the SS position but previous reports of his "cannon arm" seem overblown. He is fearless though, never being afraid or hesitant to make throws from the hole or with a runner bearing down on him when turning the double play. \

     While I am fully confident that he will continue to fill out his frame and become stronger....I do have some concerns that increased body mass could reduce his speed/range from its already average state. There should be no reason to rush Rosario at this point in time as he still needs lots of work. A full season developing in Savannah is probably the most likely scenario this year unless he absolutely mashes.

Ceiling: Solid MLB starting SS (Jimmy Rollins)
Floor: Hits the AA prospect wall.
Anticipated Assignment: (A) Savannah starting SS

Hey Chris

I just wonder, with two other very talented young guys (Guillorme and Milton Ramos) also in the pipeline, if they might be more aggressive and try to push Amed directly to St Lucie, Guillorme to Savannah, and Ramos to Brooklyn this year.

I'd like to get all 3 in full season ball this year, if ready, and not baby them.

I don't see the push happening.

Guillorme will only be 20 yr old and despite being a defensive whiz...he only posted a .661 OPS last year in Kingsport. He seems to be on the standard progression to Brooklyn.

As for Ramos....he posted a .654 OPS in 50 games for the GCL Mets which is the lowest stateside minor league team. Again he seems pegged for standard progression to Kingsport.

If either of these guys had a monster .800+ OPS season last year, I would say a level skip is in the cards....but that's not the case for either.

I hear you - I just hate prospect-quality guys being in short season leagues where they only play about half the # of games. I'd rather see a guy struggle for a few months and then still have a short season's worth of games left to progress.

Risk is a guy in short season gets hurt and gets in just 50 games, like with Cecchini in 2013.

Well to be fair Tom...most of the guys in Short Season Leagues spend their remaining time in Extended Spring Training where they receive additional instruction from coaches to improve their games.

Good point, Chris.

Like a play on words with the old song, there is nothin' you can name, that is anything like a game.

I think playing games is the fastest way to progress, but the training of short season guys is certainly helpful.
