1. Andrew Heaney, LHP

Preseason Rank: 1, Post Draft Rank: 1

MLB ETA: 2014

There is no question that Heaney is the Marlins top overall prospect. Yes, he struggled in his stint in the majors. Yes, he has struggled a bit since being demoted back to Triple-A New Orleans, but that does not change the fact that Heaney has shown flashes of the potential he has. There is a reason the Marlins refused to include Heaney in any deals at the July 31st trade deadline.

Despite his 4.34 ERA in New Orleans, Heaney has an impressive 53 strikeouts to 9 walks in 45 2/3 innings. It shouldn’t be long before Heaney dominates the Triple-A level like he the rest of his minor league stops. He’ll likely be back in Miami come September call-up time.

Heaney should be a strong number three starter that has a chance to develop into a number 2 guy.

2. Tyler Kolek, RHP

Preseason Rank: N/A, Post Draft: 2

MLB ETA: 2018

Kolek is working his way back from a back injury he sustained. Kolek featured the best fastball in 2014 MLB draft class and has the potential to be a future ace, alongside Jose Fernandez, with his top notch 100 MPH fastball. If he can develop the rest of his repertoire, he could very well reach his full potential.

Early on, Kolek has had mixed results. He has struck out 23.9% of the hitters he’s face, but also walked 15.2%. Kolek has a 5.23 ERA, but a better looking 3.53 FIP in over 10 innings of work.

What Kolek does the rest of the season isn’t likely to affect his stock. The Marlins are just getting his feet wet at this point, hoping he comes in ready to perform in 2015.

Kolek could top out as a top of the rotation guy.

3. Anthony DeSclafani, RHP

Preseason Rank: 6, Post Draft: 5

MLB ETA: 2014

Desco continues to quietly move up the prospect list for the Fish. He went from being unranked before the 2013 season all the way up to number 3 in this prospect list. The Jays decision to convert him to a starter after he was mainly a reliever as a Florida Gator has paid off for the Marlins.

Like Heaney, DeSclafani didn’t fare well in his first go-around in the big leagues. His 7.40 ERA was a cause for concern for some fans, but he has a 3.09 ERA and a 3.01 FIP at the Triple-A level as of now. If he can keep that kind of production up, he won’t be in the minors for long.

Desco has the ceiling of a number 3 guy longterm, but is more likely to be a 4 at the big league level.
