Dang @ARobsBrewCrew stole a good chunk of my answers, so I'll toss in some alternates lol
1.) Fast riser- Woodward is the one I believe in most, but I'm also a big believer in RHP Jaron DeBerry, who was a personal favorite of mine going into the draft, so I'll go with him. Those two could probably fit into the next category as well.
2.) Out of nowhere- OF Frandy LaFond (Encarnacion was going to be considered here) and RHP Dikember Sanchez (I think they use him as a starter and he blows up a bit)
3.) Rise to Top 100- OF Braylon Payne
4.) Comeback player- RHP Cameron Wagoner (I also would pick Birchard as my top choice) if we are just talking injuries. If we are just talking a bounce-back season, I'd go Wilken.
5.) Skip
6.) Predictions - Marco Dinges shows that he can stick at catcher and the bat plays and ends up a T30 guy on every list by the end of the season, Yophery Rodriguez has a higher OPS in High-A than he did in Low-A., Areinamo and Adames take some time to adjust to AA, Pratt hits 15+ HR and Brett Wichrowski raises his K% in AA by nearly 10% (idk, I'm just getting random with it now)
7.) Future star that doesn’t fit other categories - I'm copying this on Corobo, the defense/arm is special for his age and he has some pop, he has the Quero type of profile and potential breakout in him.
