Interesting. I feel like a lot of fans have soured on Groshans a bit while not doing the same with Martin.
If you look at their AA seasons, they are very similar while Groshans is about 4-5 months younger, and farther removed from professional ABs, with his injury costing him most of 2019.
Martin, age 22, 122 wRC+, 13.1 BB%, 23.4 K%
Groshans, age 21, 114 wRC+, 10.9 BB%, 21.3 K%
With that in mind, my top 10 is probably like this:
1. Moreno
2. Martin (mostly because of pedigree and draft position)
3. Manoah
4. Groshans
5. Pearson
6. Martinez (K% not great but we'll see)
7. SWR (K/9 elite but BB/9 very bad)
8. Kirk
9. Hogland
10. Lopez
