LL’s top Mariners prospects 2020: 22-19

It’s prospect ranking season! If you’ve missed any of the previous installations, you can catch up on previous lists and the introduction to the series in the main hub here. Today we close out the Top 20 with some MLB-adjacent relievers, as opposed to the other MLB-adjacent relievers we’ll be talking about tomorrow, and an exciting new addition to the infield corps.

22. RHP Dayeison Arias

Arias is a little older than the typical Latin American relief prospect who just finished his first year of full season ball due to signing at a slightly advanced age, but he’s moved quickly through the system so far and been successful at every stop in the low minors.
