Top 10 Prospects (2018): Miami Marlins: Is There Any Potential Upside To Be Found?

by Eric Stashin (aka The Rotoprofessor)

The Marlins were already considered to own one of the worst farm systems in baseball, yet they still thought it was a prudent decision to trade Luis Castillo prior to ’17.  How does that look today?  If he were still part of the system he would be the clear top rated prospect, but instead they are left with significant questions and a potential lack of upside.  Health concerns have definitely helped push things down, and maybe things look different a year from now, but we are where we are.  Let’s take a look at one of the most underwhelming systems in the league:

 

1) Trevor Rogers – Left-Handed Pitcher
Grade – B
ETA – 2020

Rogers takes the top spot, though basically by default.  The 2017 first round pick (13th overall) has not yet thrown a professional pitch and there are questions about his pure stuff.  Reports have his fastball sitting in the low 90s and his secondary stuff is still developing.  He does have the size (6’6”), some deception and is a southpaw, and that’s all going to give him an opportunity.  He could develop into a solid MLB starter, but a future ace is not a label we’d be willing to give.

 

2) Braxton Garrett – Left-Handed Pitcher
Grade – B
ETA – 2020

Garrett showed strong signs early in ’17, with 16 K vs. 6 BB over 15.1 IP, but that’s all we got from the seventh overall pick in 2016 after he was shelved and underwent Tommy John surgery.  It’s a shame, as he certainly would’ve taken home the top spot if he had been healthy, and the fact that he’s still ranked #2 speaks to his upside as well as the state of the Marlins’ system.

He does take a hit in his grade, after being a B+ last season, thanks to the uncertainty in regards to his return from Tommy John surgery.  While history tells us he should be alright, there are many examples of pitchers never being the same.  Time will tell, but don’t lose hope.

 

3) Dillon Peters – Left-Handed Pitcher
Grade – C+
ETA – Already Arrived

He struggled to a 5.17 ERA over 31.1 IP in his first taste of the Majors, and that’s going to cause many to look away.  He also generated a 63.3% groundball rate, after a 50.0% mark in the minors in ’17, and has shown an ability to generate swings and misses (11.6% SwStr% in the minors).  Couple that with pinpoint control, despite a 5.46 BB/9 in the Majors (1.9 BB/9 over 236.2 IP in the minors), and it’s obvious that there’s upside.  Further skewing things is his size, as he’s listed at just 5’9”, and consistent injury issues (he’s already had Tommy John surgery and missed time in ’17 after breaking his thumb) that have delayed his ascent (he’s now 25-years old).

Peters may require some time at Triple-A, having jumped to the Majors after 68.1 IP at Double-A split between ’16 and ’17, and that could cause others to ignore him.  Of course how far his stock rises remains to be seen and his overall upside is limited.

 

4) Brian Anderson – Third Baseman
Grade – C+
ETA – Already Arrived

On the surface things looked good for Anderson, hitting .275 with 22 HR in 429 AB split between Double and Triple-A.  The number is skewed by an unsustainable 19.7% strikeout rate, which came despite a 12.0% SwStr%, as well as a .376 BABIP at Triple-A that led to a .339 AVG.  He was exposed a bit in his 95 PA in the Majors, where he posted a 29.5% strikeout rate courtesy of a 12.8% SwStr%.

While there is some pop, he only added 21 doubles and 3 triples in the minors and his home ballpark isn’t going to be conducive to power.  It looks like he profiles as more of a .250ish/20 HR type player, especially as it’s hard to project further growth from the 24-year old (he’ll turn 25 in May).

 

5) Tyler Kolek – Right-Handed Pitcher
Grade – C+
ETA – 2019

Tommy John surgery has cost him virtually two years of his development, losing all of 2016 and being limited to 3.2 innings last season.  The second overall pick back in 2014, he brings the potential to be the top prospect in the system as he can generate both strikeouts and groundballs.  His health and control are the significant questions, and we’ll get a good feel for those early in 2018.  Could he ultimately become a “B+” type prospect with top of the rotation stuff?  It’s absolutely possible, though hardly a given.  Consider him high risk, high reward.

 

The Next Five:
6) Brian Miller – Outfielder (Grade – C+)
7) Trevor Richards – Right-Handed Pitcher (Grade – C)
He’s 24-years old and could ultimately profile as a reliever given questionable stuff, but over 146.0 IP he posted a 9.74 K/9, 1.85 BB/9 and 54.5% groundball rate.  Don’t be a surprised if he starts garnering more attention and gets an opportunity to make an impact in ’18.7)
8) James Nelson – Third Baseman (Grade – C)
9) Merandy Gonzalez – Right-Handed Pitcher (Grade – C)
10) Jeff Brigham – Right-Handed Pitcher (Grade – C)

 

Keep An Eye On
Thomas Jones – Outfielder (Grade – C)
He was a “C+” a year ago and ranked #6 in the system, and the athleticism is clearly there.  He needs time, though, and 94 K over 238 AB (32.2%) at Low-A shows it.  It’s a high ceiling, but an extremely low floor.
