My favorite prospect in the Seattle Mariners system is this brawny youngster from Cartagena, Colombia. I liked Michael Arroyo immensely since signing, as there’s a compelling projection to me in prospects with experience and performance at the national level for their country. The compact infielder was already a top-notch performer for the Colombian youth team before signing with Seattle for the largest bonus inked by any player in the history of his country. Those expectations haven’t crushed the 20 year old; in fact, to the contrary. He enters 2025 on the heels of a star turn in World Baseball Classic qualifiers for his country, and having starred at the Low-A Modesto and High-A Everett levels as a teenager in 2024.
