The Red Sox signed two of MLB.com‘s Top 50 International Prospects on Thursday, the first day of the new signing period.

Boston gave a reported $1.2 million bonus to 17-year-old Dominican shortstop prospect Dawvris Brito, who’s ranked No. 28 on MLB.com’s list and a $1.4 million bonus to 17-year-old Dominican outfield prospect Garielvin Silverio, who’s ranked No. 36.

Baseball America’s Ben Badler was the first to report both Silverio and Brito’s bonuses.

Silverio’s MLB.com scouting report describes him as “a physical specimen” and “a supremely hard worker who has maximized his impressive physique to emerge as an exciting offensive prospect in the 2026 class.”

He’s listed at 6-foot-1, 207 pounds and projects as a corner outfielder. MLB Pipeline grades his power 55 (above average) on its 20-80 scale. It has his hit tool graded at 50, the major league average. He turned 17 in October.

MLB Pipeline wrote, “That smooth left-handed swing, and the ability to leverage it for extra-base power, has helped Silverio excel during in-game action. His head stays still throughout his swing and he features a slight toe tap as a timing mechanism, which when coupled with his plus bat speed and 207-pound frame, helps the ball really jump off his bat. He’s able to make contact with a variety of pitches, but as he gets into the professional ranks, he’ll continue to focus on mashing the driveable ones to maximize his power-to-all-fields profile.”

Brito is listed as a 6-foot, 177-pound shortstop and turned 17 in September. MLB Pipeline grades his hit, arm, field and run tools 50 (average) on the 20-80 scale. His power is a little below average (45 grade).

MLB Pipeline wrote, “Brito has a really strong understanding of the strike zone, which when coupled with his quiet hands and plus bat speed, allows him to consistently generate loud contact. A right-handed hitter, he has routinely been ripping off triple-digit exit velocities over the past year and has begun to grow into some strength as his frame fills out. He utilizes a short stride at the dish but is still able to get to his power, which should only continue to come as he garners more in-game reps.

“Quick actions and smooth hands work in Brito’s favor as an up-the-middle defender. Some evaluators believe that even if he’s forced off the premium spot of shortstop, he would transition well to the outfield where his long strides would work in his favor. Brito has the build and look of a potential five-tool prospect, upside he will look to capitalize upon as he gets his pro career under way.”

Francys Romero reported via X that the Red Sox also have signed Dominican outfielder Joskairo Ramirez for $800,000, Dominican infielder Esterlin Casanova for $650,000 and Brazilian right-handed pitcher Claudio Pereira for $500,000.

Baseball America, which also reported Ramirez’s bonus, wrote, “At 5-foot-10, 170 pounds, Ramirez isn’t that big, but he’s strong and has great hand-eye coordination that leads to high-end bat-to-ball skills with gap power. Ramirez is instinctive in the batter’s box and in center field. Despite tick-below-average speed, Ramirez gets great reads off the bat and takes clean routes to cover ground well in center field, giving him a chance to stick in center field, though his pure foot speed is below typical for the position.”

Baseball America added about Pereira, “His fastball scrapes 90 mph with a frame that screams projection for him to add significantly more velocity once he gains weight. It’s an easy operation for Pereira, who pitches with steep angle and shows feel for a changeup that he leans on heavily and is ahead of his curveball.”
