23 is still pretty young, he will also be 23 to start next season. Bello advanced at least a level each season he's been in the system, actually two levels his first year, two his 3rd year, and 3 this year. He signed at 18, two years older than the typical IFA prospect and missed an entire year due to covid. All things considered, he's flown through the system. He also struggled, not a lot but a little at Portland when he first arrived in 2021 then he adjusted quickly and became dominant. His stuff has ticked up and improved every year he's been in the system.
Given a clean bill of health, he could be a regular in the rotation at some point next season.
