Historical Context

The November 17, 1992 expansion draft stocked the Colorado Rockies and Florida Marlins for their 1993 debut, expanding the National League to 14 clubs. Seattle Mariners responded by boosting Latin-American scouting, increasing Colombian signings 40 % to twelve by 1995. In 2024 the Mariners signed 21-year-old Michael Arroyo to a $1.375 million bonus, the largest for a Colombian prospect.
