Post-Prospect Scouting Reports
Yesterday, Kiley and I ranked the prospects who graduated in 2017. As part of the that re-evaluation exercise, I came across a subset of players whom I thought merited a deeper dive. Many prospects “graduate” off of prospect lists but remain unfinished developmental projects who get bounced to and from Triple-A for an extended period of time. Others get hurt at an inopportune time and virtually disappear for years.
Nobody really covers these players in a meaningful way; they exist in a limbo between prospectdom and any kind of relevant big-league sample. To address this blind spot in coverage, I’ve cherry-picked some of the more interesting players who fall under this umbrella — players who have either made relevant changes or whose profiles have changed based on relevant info we could only have learned with a big-league sample.
As far as Future Value grades for this group are concerned, they look like this:
| Name | Org | Position | FV |
|---|---|---|---|
| Francis Martes | HOU | RP | 55 |
| Tyler Glasnow | PIT | SP | 50 |
| Miles Mikolas | StL | SP | 50 |
| Jurickson Profar | TEX | UTIL | 45 |
| Daniel Mengden | OAK | SP | 45 |
| Andrew Heaney | LAA | SP | 40 |
| Bryan Mitchell | SD | SP | 40 |
| Dalton Pompey | TOR | OF | 40 |
| Cody Reed | CIN | RP | 40 |
| Charlie Tilson | CHW | OF | 40 |
| Amir Garrett | CIN | LHP | 40 |
| Henry Owens | LAD | LHP | 35 |
Now, on to the reports.
*****
Francis Martes, RHP, Houston Astros
Martes’s stuff is nasty enough that he’s very likely to play a significant big-league role even if he never develops starter’s command, and Houston obviously has a recent history of finding ways to maximize what guys with fringey command — like Lance McCullers and Brad Peacock, for example — are able to do. Martes sits 95-99, while his mid-80s curveball features a spin rate around 2600 rpm. Curveballs with that combination of velocity and spin are rare. Jose Fernandez, Ariel Hernandez, and Yordano Ventura are all recent peers by that criteria. Scouts think it could be a 70 curveball.
