Agreed on the SP, the 65/80/60 pitch quality is interesting and why I don't have a great comp either. When I saw that P1 wasn't above 70 I got concerned.
Avisail Mujica, was the closest I could get. I'd be curious to see what people think about him in 10 seasons.
The catcher comps to a guy I drafted a few seasons back, just the C has less speed.
Juancito Martin is a .300+ hitter with 25ish HR. With a lot less speed, I question how many XBH he'll end up having. Might be a Single, BB, or HR type of hitter. I like him over the RF; not a great comp but the closest I got was
Olmedo Nunez but your guy is project -5 Con, -4 Pwr, +15 vR, +7 eye with +40 spd. So obviously not really a great comp at all.
Depending on needs of the team and availability of talent in the league (Cobbfather is lacking good starting pitching right now) I'd probably go C - SP - RF. I typically rate COF and 1B a little tougher because the positions are a little easier to fill it seems.
