Mariners Bolster Farm System With Top International Talent

The Seattle Mariners have significantly bolstered their already impressive farm system by securing three top prospects from MLB Pipeline's Top 50 international list. The newly acquired talent includes outfielders Juan Rijo, ranked 12th, and Gregory Pio, ranked 32nd, along with shortstop Leonardo Reynoso, who is No. 48. These signings mark a strong start to the 2026 international signing period for the club.

Rijo, noted for his power and hitting ability, is expected to contribute offensively, potentially at a corner outfield spot. Pio brings speed and raw power, with his running ability being a key asset, though he will need to refine his pitch selection. Reynoso, considered the top infield prospect in this year's group, boasts a strong arm and switch-hitting capabilities, projecting as a potential middle infielder or third baseman.
