Boston Red Sox 2025 International Signings Review

Top Of The Class

The biggest bonus of the Red Sox class this year went to Dorian Soto, a 17-year-old Dominican shortstop who got $1.4 million. Soto is 6-foot-3, 185 pounds with the look of a player who might not be done growing. It’s a huge frame with lots of room to still fill out and he already generates big bat speed. Soto generates force and explosion with his lower half to produce that bat speed and raw power that should end up a plus or better tool. Some scouts had concerns about swing-and-miss with Soto earlier in the evaluation process, but he uses his hands well and has shown solid bat-to-ball skills for a long-limbed hitter.

There’s big offensive upside with Soto, who will start his career at shortstop but may not stick there. He has the hands for the infield, his footwork has improved and he has a solid-average arm, but his size and range likely pushes him elsewhere. Third base would be an ideal fit if he can handle that position, though there’s a chance he ends up so big he could head to first base or an outfield corner as he gets closer to the big leagues. 

Venezuelan center fielder Harold Rivas, who just turned 17 in May, is an elite athlete with exciting tools at a premium position who signed with the Red Sox for $950,000. He’s 6-foot-2, 180 pounds with wide shoulders and quick-twitch, explosive actions at the plate and in the field. He’s a plus runner with a quick first step and strong defensive instincts, getting excellent reads off the bat and taking efficient routes. That all translates to excellent range to go with a plus arm that could still get stronger as he fills out, giving him the attributes to be a plus or better defender in center field.

The athleticism and tool set has similarities to Red Sox outfield prospect Miguel Bleis and some scouts drew comparisons to Mets outfielder Jose Siri, with some seeing better offensive upside. Rivas isn’t a refined hitter, but he has high-end bat speed from the right side of the plate. He can drive fastballs well and backspin balls to the middle of the field, though he’s more susceptible against breaking stuff, but he has the power potential to be a 20-25 home run hitter if he proves he can make enough contact. 

Names To Know

Hector Ramos, SS, Dominican Republic: Ramos, who got $500,000, is a 17-year-old switch-hitter who has hit well in games and projects to stick at shortstop, making him one of the more promising mid-range bonus position players signed in 2025. He’s 6-foot-1, 175 pounds with good bat control, putting balls in play at a high clip with occasional over-the-fence juice to his pull side. It’s a hit-over-power profile now, but with power that’s ticking up as he’s steadily added strength with a chance to develop into a 20-plus home run threat. Ramos has good hand-eye coordination that shows at the plate and at shortstop. He’s a fringe-average runner who isn’t a quick-burst athlete some teams prefer at shortstop, but he has great body control and is light on his feet with soft hands and an above-average arm. 

Sadbiel Delzine, RHP, Venezuela: Delzine signed for $500,000, the top bonus for a Venezuelan pitcher signed in 2025. He’s one of the best pitchers in the 2025 class, combining physical upside, power and pitchability. Delzine has grown to 6-foot-6, 200 pounds. It’s monster physicality with a fastball that touched 94 mph heading into his signing, has since reached 96 and he has the look of a pitch who could one day throw 100 mph. Delzine’s power arm is exciting, but he’s more than just raw arm strength. He has good control for a 17-year-old thanks to athleticism that helps him repeat his delivery and shows feel for three pitches, including a curveball that’s ahead of his changeup. 

Eliezer Alfonzo, SS, Venezuela: The Red Sox signed Alfonzo, a 17-year-old switch-hitter, for $700,000. Alfonzo is 5-foot-11, 165 pounds and stands out more for his instincts and high baseball IQs than his raw tools. He has good bat-to-ball skills, spraying line drives around the field with doubles power. Alfonzo’s defensive game is more about instincts than quick-twitch athleticism. He trained as a shortstop and could see time there but is likely to move all around the infield, with the actions and internal clock to play somewhere in the dirt. 

Christopher Cordero, RHP, Dominican Republic: Cordero is still 16, one of the younger players in the 2025 class, and signed with the Red Sox for $400,000. He’s 5-foot-11, 180 pounds, a compact build with a strong lower half that doesn’t have huge physical projection, but he’s athletic, flexible and has seen his fastball inch up from touching 92 mph before signing to now reaching 94. He throws from a low release height and pairs his fastball with a high-spin curveball that has good depth for a north-south attack, rounding his repertoire with a changeup. 

Adrian Valdez, OF, Dominican Republic: Valdez is a physical slugger at 6-foot-3, 230 pounds with big righthanded power. Signed at 17 for $300,000, Valdez has the explosive bat speed and strength to produce impressive power displays, showing some feel for hitting but standing out more for his power than pure hitting ability. He’s a corner outfielder who moves well enough to develop in a corner outfield spot, with some risk given his size that he could go to first base. 

Enmanuel Figuereo, OF, Dominican Republic: The Red Sox signed Figuereo, 17, for $250,000. He’s 6 feet, 165 pounds with a promising mix of athleticism and righthanded hitting ability. He’s a quick-twitch athlete with plus speed in center field and has shown an advanced offensive approach for his age, performing well against live pitching with a sound swing to lace line drives to all fields with gap power. 

Sleeper Watch

Jhorman Bravo is a 16-year-old, lefthanded-hitting shortstop the Red Sox signed for $150,000. Bravo has stood out for his hitting ability, but his overall profile has improved as he’s gone from a player who weighed 150 pounds when teams were scouting him as an amateur to now 6-foot-1, 180 pounds. Bravo has large, strong hands and a mature offensive approach, staying through the middle of the field with a mechanically sound swing and good feel for the barrel. It’s a hit-over-power offensive game but with more bat speed and power that he’s added over the past year. More of his doubles that should turn into home runs given his age and room to still fill out. Bravo isn’t a big runner, but he handles himself well at shortstop and should get a chance to stick there, though he could see time all over the infield this year to get regular playing time.
