Seattle Mariners 2026 International Class Scouting Report

The top prospect the Mariners are signing is Dominican outfielder Juan Rijo, who is getting $2.2 million. Rijo has long stood out for his hitting ability since he was a smaller player early in the process, whether it was facing pitchers his own age or barreling up opponents several years older than him. Since then, Rijo has continued to show polished hitting ability for his age while growing to 6-foot-1, 185 pounds. He’s a lefty with sound swing mechanics, taking a tight turn of the barrel into a balanced swing. He recognizes pitches and takes a short, direct path with an approach geared to use the whole field. Rijo has the components to get on base at a high rate and has added strength to be able to drive the ball out of the park now to his pull side with the bat speed and physical upside to grow into a 20-plus home run threat. Rijo is an average runner who could slow down as he fills out and projects best as a corner outfielder.

The biggest bonus of Seattle’s class is going to Dominican outfielder Gregory Pio, who is signing for $2.9 million. Pio’s athleticism and tool set at a young age made him an early standout in the 2026 international class. He’s a quick-twitch athlete with plus-plus speed, giving him the wheels and range to handle center field. At the plate, Pio’s righthanded swing can get big at times and he has some things to iron out mechanically. But he has a lean, tapered build (5-foot-11, 170 pounds) with the bat speed to hit balls out of the park to his pull side and room to fill out to continue adding power. His speed gives him a chance to be a high stolen base threat.

Dominican shortstop Leonardo Reynoso is a stocky, 5-foot-10 switch-hitter who is more advanced from the left side, where he has shown good adjustability with his swing to make frequent contact with a line-drive approach and mostly gap power. Reynoso’s bat is ahead of his defense, likely fitting best at either second or third base with an above-average arm that would play at either position, though his range might be best suited at third base. Between his body type and arm strength, Reynoso would also be an intriguing catching conversion candidate, but he has trained and will sign as an infielder.

Venezuelan catcher Daniel Alaña ($600,000) is a righthanded-hitting catcher with a power stroke. It’s an uppercut swing geared to lift the ball, which can come at the expense of contact, but he generates good bat speed to drive the ball out of the park to his pull side with above-average power potential. At 5-foot-11, Alaña has a strong, thicker build that he has worked hard to stay on top of his conditioning and enhance his athleticism. His power and above-average arm strength are his two standout tools.

Dominican outfielder Ambeiro Recio, signing for $400,000, has a strong, physically mature 6-foot-1 build for his age with broad shoulders. Strength and power are the calling cards for Recio, who can put on a show in batting practice and could end up with plus-plus raw power. There’s some swing-and-miss that comes with his power, but if Recio can keep it to a manageable level, the power will fit in an outfield corner. 

Jarvin Gomez is an intriguing sleeper as a Dominican outfielder who went under the radar but has loud tools for a lower bonus player. At 6-foot-1, 170 pounds, Gomez is a plus runner with a plus arm in center field. It’s not the most fluid swing, but he generates a lot of bat speed and power, making for a lot of physical traits to like if things click with the bat.
