To Mariners fans, Michael Arroyo isn't exactly a new name. He has been a Top 30 prospect for the organization since he was signed as an international free agent in 2022 and heading into 2026, he's ranked as the team's No. 5 prospect for MLB Pipeline.
He had just seven spring training at-bats but made the most of his limited opportunities, posting a 1.779 OPS before leaving to join Team Colombia in the World Baseball Classic. While many prospects are trying their best to potentially get a crack at the Opening Day roster, Arroyo decided that the best way to showcase his talents was for his country, and he didn't disappoint.
