Scouting Report

Scouting grades: Hit: 45 | Power: 55 | Run: 60 | Arm: 55 | Field: 55 | Overall: 45

The top signing in Boston's 2020-21 international class, Bleis earned a $1.5 million bonus on the basis of his electric bat speed and potential to become a five-tool center fielder. Excitement grew when the Dominican was clearly the best prospect in the Rookie-level Florida Complex League in his U.S. debut in 2022, seemingly setting the stage for a full-season breakout last year. But he swings so hard that he subluxated his left shoulder last May and required season-ending surgery.

Bleis already has jaw-dropping raw power at age 20 thanks to his bat speed, still-developing strength and the loft and leverage in his right-handed swing. He aggressively looks to launch balls to his pull side, producing high exit velocities for a 20-year-old but also leading to chases and strikeouts. He'll need to improve his swing decisions and his patience as he starts to face more advanced pitching.

Evaluators give Bleis solid-to-plus grades for his speed, arm and center-field defense. He already has gained 20 pounds since turning pro and could lose a bit of quickness as he continues to add muscle, but even so his instincts will enable him to continue to be an asset as a runner and defender. He looks to make things happen on the bases and makes good reads in center.

Bleis landed the largest bonus in Boston's 2020-21 international class, signing for $1.5 million out of the Dominican Republic as a center fielder with the potential for at least solid tools across the board. That's exactly what he looked like in his U.S. debut last summer, when he batted .301/.353/.542 with 23 extra-base hits and 18 steals in 40 games in the Rookie-level Florida Complex League. The Red Sox's best international prospect since Rafael Devers, he subluxated his left shoulder on a swing in late May and had season-ending surgery.

Built to hit for power, Bleis has a quick right-handed swing with loft and a 6-foot-3 frame with plenty of projectable strength and leverage. He also has an aggressive approach geared to launch balls to his pull side, which helps produce impressive exit velocities for a teenager but also portends the need for adjustments and better swing decisions against more advanced pitching. He does have some feel for recognizing pitches and discerning strikes, so there's optimism that he can become at least an average hitter, which would make him a star. 

Bleis' present speed earns 55-65 grades on the 20-80 scouting scale, and he likely will settle on the lower end of that range once he matures physically. He uses his quickness well, stealing and taking extra bases and effortlessly covering ground with long strides in center field. He also features solid to plus arm strength and would be an asset at any outfield position.

Bleis signed for $1.5 million out of the Dominican Republic in January 2021, securing the largest bonus in Boston's 2020-21 international class. He made a successful pro debut in the Rookie-level Dominican Summer League, batting .252/.331/.420 with four homers and seven steals in 36 games at age 17. He has one of the highest ceilings in the system with the potential for solid tools across the board. 

Bleis has a sound right-handed swing and a feel for the strike zone at a young age. His bat speed, projectable strength and the leverage in his 6-foot-2 frame give him plus raw power. He makes a lot of hard contact already and shows the ability to drive balls in the air to his pull side. 

Though Bleis currently has plus speed to match his raw pop, he likely will slow down a bit as he matures physically. His gliding strides eat up a lot of ground in center field, and he should have the quickness and instincts to stay there. If he had to move to a corner, his solid to plus arm strength would work in right field.

At 6-foot-3 and 175 pounds, the athletic Bleis is one of the biggest and strongest prospects on the international market. It’s this projectable body combined with a mixture of potential plus tools that makes him so appealing to evaluators.

 At the plate, Bleis already exhibits average raw power and it’s expected to improve to a plus tool as he continues to develop. He also shows a short and compact swing with tons of bat speed. The teenager has impressed evaluators with his ability to drive the ball to the gaps and hit home runs with frequency in showcases and games. Bleis has a plan once he steps into the batter’s box with a feel for the strike zone and it shows. 

On defense, he shows good instincts in center field and also has plus arm potential. Additionally, the speedy outfielder has a chance to be a plus runner. Bleis trains with Luis Pereira at the Mejia Top 10 Baseball Academy in the Dominican Republic. The Red Sox are the favorite to sign him.
