Yep none of them made my initial sort trying to figure out who debuted at 20 with experience below AA. The debut at 20 pool is pretty small with just 141 pitchers in my lifetime (45 years) that made their debut at 20. Of those 141 only 32 had an fWAR of 1 or higher, and 89 were above replacement level. As BTS said, his best case scenario is low impact and it starts his clock and burns an option if you send him down. The positives just don't outweigh the negatives here.
