Behind a paywall, we have 4 on the list:
Adley: 2
GRod: 30
Mountcastle: 93
DL Hall: 97
His write up on Grod is very nice:
”Rodriguez was a surprise pick at No. 11 overall in the 2018 draft, both since he was generally thought to go in the back half of the first round and also because he was generally seen behind Matthew Liberatore (80th on this list) and Cole Winn (45+ FV).
Obviously, Baltimore has been more right than that consensus so far and much of that is due to how quickly Rodriguez has made adjustments. While I was at FanGraphs, I took high-speed video of Rodriguez in the Futures Game and saw the mesmerizing screwball-like action he was getting on his new changeup. It went from being a distant third pitch that was never much better than average to a plus pitch. Some of the pitch-design things that Houston is known for (Verlander's new arm slot, fastball spin, etc.) are at work here with former Houston people running the show in Baltimore.
Rodriguez now has four above-average to plus pitches with starter command. If he had a 2020 minor league season, it would not be surprising to have seen him steamroll his way to Double-A and be comfortably in that top tier of troublesome-to-sort pitching prospects above. Only having experience in low-A and not having one 70-grade projected pitch are the two things holding him back thus far, but Rodriguez actually doesn't have a clear concern like all of them do.
Rodriguez may be underranked here, but he'll likely move up 10-15 spots with a strong first half of the 2021 minor league season, as his questions melt away while other prospects graduate.“
