Prospect Spotlight

Signed for just $50K in 2016, Adon’s stuff has turned heads through the low parts of Washington’s system. He spent his first year in pro ball in the DSL, coming stateside last summer and splitting time between the GCL and New York-Penn League. The Nationals moved the 20-year-old righty to Hagerstown’s rotation this year, and while he ultimately is more likely to wind up back in the ‘pen, facing lineups numerous times and working late into games is good for his development.

Adon’s fastball works in the 93-to-97 mph range as a starter, hinting there’s even more velocity to come if he’s back in a relief role at any point. The pitch flashes occasional lively armside run, though his command and general pitchability are still fairly raw. His primary off-speed is a hard mid-80s slider, showing tight rotation and bite at times. He doesn’t finish the pitch consistently but the signs of a playable big league breaking ball are there. Adon’s changeup is a nascent third offering that lags behind the rest of his arsenal.

The arm-strength makes him a prospect, though Adon’s lack of size, third pitch, and present mechanical effort makes him a better long-term fit in the ‘pen. He has the stuff to fit a middle relief or 7th inning setup role with more breaking ball consistency and continued refinements to his strikethrowing.
