The models like him.
Former NC Dinos Ace, Arthur Wesley Parsons, was one of the best pitchers in the KBO in 2021 and for a brief time in 2022. His K/9 was among the elite during such period.
In 2023, in 81.2 innings at the AAA level, Arthur Wesley Parsons had a K/9 in the top 4 among SP with at least 80 innings, slotting in behind real prospects Robert Gasser, Drew Rom, and Jared Jones, and above real prospects like Gavin Stone, Joey Cantillo, and Juan Soto trade headliner Randy Vasquez.
Steamer presently projects him for a sub 4.00 ERA in relief, while ZIPS thinks he could be an above replacement level arm in a swing-role.
The Blue Jays probably think he could be competent arm for ~3 innings if they are desperate. He might be better than a random prospect, like Chad Dallas and Luis Quinones, and he might project better than most of the presently willing MiLB potential signees. He might be able to miss bats, for one turn through the order.
