Background
Arroyo grew up in Cartagena, a city with real baseball roots in Colombia. His path to the majors followed the road many Latin American prospects know well: academies, the minor league grind, and steady development over time. Seattle’s decision to bring him up reflects the organization’s ongoing commitment to finding versatile, high-ceiling talent at shortstop.
A right-handed hitter and thrower, Arroyo made his debut in the final stretch of the 2026 season, wearing Seattle’s navy blue for the first time as a 21-year-old still in the early stages of his professional growth.
Professional Career
In his debut 2026 season with the Mariners, Arroyo posted a .000 AVG, 0 HR, 0 RBI, 0 runs and a .000 OPS — numbers that honestly tell the story of any young prospect getting his first taste of big-league competition. His appearances were limited, which is par for the course when an organization is being careful with a 21-year-old still finding his footing at the highest level.
The Mariners are keeping him in the fold with an eye on what he can become offensively and defensively. His youth and positional value make him one to watch as the seasons ahead unfold.

Awards and Records
Still in the earliest chapter of his MLB career, Arroyo hasn’t collected individual hardware yet — no Silver Slugger, no MVP votes, no All-Star nods. That’s all ahead of him. The recognition will come if he develops the way Seattle is hoping he will.
Worth Knowing
Arroyo’s arrival in Seattle at 21 is a reminder of how consistently MLB organizations scout and develop Colombian talent. The Mariners have made a habit of building their infield depth through international prospects, and Arroyo fits squarely into that philosophy — a young player from a baseball-loving country getting his shot at the biggest stage in the sport.
