Roman Anthony, OF, Boston Red Sox

AAA, Age 20

Starting with his contact and approach at the plate, Anthony starts with his hands and a slightly open stance. He uses a leg kick to create quite a wide stance but helps create good hand-to-hip separation. Leading with his body, Anthony creates good lag with the bat thanks to his strong hands and electric bat speed. His bat speed ranks at the very top of all hitters in baseball.

Given the bat speed, the power metrics are off the charts, though, as Anthony has a 90th percentile exit velocity near 109 mph. Topping out north of 116 mph and showing solid average exit velocities, Anthony easily shows plus or better power. The biggest flaw with the power is a ground ball rate just shy of 48 percent which is something to watch.

The plate discipline skills are impressive, and Anthony knows the strike zone as well as anyone. He chased just 21 percent of pitches out of the zone. The contact skills follow along right with the discipline, as Anthony posted a 75 percent overall contact rate with an 83 percent in-zone mark.

Anthony is an above-average runner at present and stole 21 bases on 28 attempts last season. He is likely to slow down with age and as he continues to fill out his frame. Anthony is a plus glove as well, with an above-average arm. He likely fits into right field in Fenway Park, which plays to his strengths.

If you want to poke a hole in Anthony’s game, it is the amount of ground balls he hits. But considering how hard Anthony hits the ball, he is actually able to run higher BABIPs. With a slight tweak in the swing path, Anthony could unlock 30 home runs in the majors. The skills are there, and Anthony is going to be an awesome player for a long time.

3 hits and 3 RBI tonight for Roman Anthony. Drove in all 3 of the Drive's run in a a 3-0 win.@SoxProspects pic.twitter.com/ks6XPTUkLm

Dylan Crews, OF, Washington Nationals

MLB, Age 23

After being selected second overall in the 2023 MLB Draft, some struggles in Double-A started to cause some questions surrounding Crews. One of the most decorated college hitters in the last 10 years, Crews posted a collegiate slash of .380/.498/.689 with 58 home runs across 983 plate appearances. He struck out just 15.5 percent of the time while walking 16.2 percent.

Crews put up solid numbers in Double-A and Triple-A in 2024, posting a combined slash of .270/.342/.451 with 13 home runs and 40 extra-base hits while stealing 25 bases. Sure, it was not a dominant showing, but Crews was good enough to earn a call-up to Washington, where he played his final 31 games.

While he did not light the world on fire and blossom into a superstar in year one as many hoped, the underlying data still looks strong. Crews posted a 90th percentile exit velocity north of 106 mph and an average of around 90, both solid marks.

From a contact standpoint, Crews posted above-average rates, 76 percent overall and 87 percent in-zone and both the contact and exit velocity data were held in his MLB sample. Crews did show more chase, but I honestly think some of his aggression and higher swing rates are good compared to what we see in college.

Posting strong sprint speeds and being highly efficient on the base paths led Crews to steal 37 bases in 2024 while only being caught eight times. Being strong in the field also helps his well-rounded profile and allows Crews to be a lock to be in the Nationals lineup every day in 2025 from Opening Day.

Jasson Dominguez, OF, New York Yankees

MLB, Age 22

One of the most hyped prospects on the international market in the last 10 years, Domínguez, deemed “The Martian,” was unfairly compared to players like Mike Trout, Bo Jackson, and Mickey Mantle. No one can live up to those kinds of comps, but Domínguez has been pretty "dang" if we say so ourselves.

Domínguez made his MLB debut in 2023 and was dominant before a UCL injury ended his season after just 33 plate appearances. An oblique injury in addition to the UCL limited him in 2024, but when on the field, the results were good.

Spending the majority of the year in Triple-A, Domínguez slashed .314/.376/.504 with 11 home runs and 20 extra-base hits in 58 games. He stole 16 bases and was caught just once. While the MLB surface numbers were not great, Domínguez kept strong numbers under the hood.

A few mechanical tweaks helped lead to the breakout in 2023, including limiting his leg kick and hand load.

The power is legit, as Domínguez posted a 90th percentile exit velocity of 108 mph, putting the power grade firmly plus or better. The contact rates also made a massive jump throughout his career. In the minors, Domínguez posted a 78 percent overall mark and an 89 percent in-zone contact rate. Those numbers carried over to the majors.

The speed has remained despite Domínguez’s body fluctuating in size throughout the early parts of his career. He stole 21 bases between the majors and minors and was caught just once.

Given how hard Domínguez hits the ball, he creates barrels often. People have been quick to point to his 62 percent ground ball rate in a small MLB sample, but it seems that it is primarily related to his oblique injury.

For his career, that number has sat around 45 percent, a solid number given Domínguez’s batted ball profile. He is slated to be an everyday outfielder in 2025 for the Yankees and could be a favorite for AL Rookie of the Year.

Sebastian Walcott, SS, Texas Rangers

AA, Age 19

If you crafted the body of a future star player in a lab, Walcott is what they would look like. Standing at 6-foot-4/190, Walcott won’t turn 19 until Spring Training 2025 is nearly over, yet he has already reached Double-A.

The Rangers have been aggressive with him, sending him from the complex to High-A after he signed in January 2023, and then Walcott spent nearly all of 2024 with High-A Hickory before ending the year in Double-A.

After some struggles out of the gate, and to no one’s surprise, Walcott progressed all year and wound up slashing .265/.344/.452 with 11 home runs, 34 doubles, and nine triples. He stole 27 bases and was caught just eight times. While some reports have quickly written him off as a shortstop, Walcott shows impressive range there and has smooth actions with a big arm.

While the 25.6 percent strikeout rate is a bit concerning, and the contact rates don’t paint a pretty picture, things improved. Over his final three months, Walcott struck out less than 23 percent of the time.

The contact rate finished the year at 67 percent, and his in-zone mark was below average at 78 percent. Walcott chased pitches out of the zone at a 27 percent clip. When examining these marks, it is important to remember that he was an 18-year-old in High-A and Double-A.

The power and athleticism are off the charts, though. Walcott’s 90th percentile exit velocity of 106 mph was top of the scale for his age, and he paired it with an impressive 116.3 mph max. Nearly 60 percent of Walcott’s batted balls were in the air, and his pull percentage of balls in the air was 90th percentile for all hitters.

The foot speed is plus Walcott uses it on the bases and in the field. The swing is solid, and the bat speed is electric. He does wrap the bat around his head ever so slightly but creates good separation with a wide base, helping him generate torque and power.

From a pure upside standpoint, this is what a No. 1 overall prospect looks like. Will Walcott make enough contact to make the profile work? That is still to be determined, but even if he is a 30-grade hit tool, the rest of the profile will allow him to be an everyday major leaguer.

Not that you need more Sebastian Walcott propaganda, but this guy scorches baseballs. 4 100+ MPH EVs last night, including a 111. He turned 18 years old in March. pic.twitter.com/JCH1tdbtLe

Kristian Campbell, INF/OF, Boston Red Sox

AAA, Age 22

Campbell had an extraordinary year, and there is a clear reason why he was named Minor League Player of the Year by multiple big outlets. Ascending from High-A to Triple-A by season end, Campbell slashed .330/.439/.558 in 517 plate appearances. Campbell blasted 20 home runs and had 32 doubles and three triples to have an impressive 55 extra-base hits.

Early in the year, Campbell was trading his strong contact skills for power. In the first two months of the season, Campbell had a contact rate below 73 percent, which was a massive outlier from what he had been throughout his playing career. Month by month, Campbell found a way to blend his strong contact skills with impressive power gains.

From June forward, his overall contact rate was north of 82 percent, with an in-zone mark near 90 percent. He finished the season with a 78 percent overall mark and an 83 percent in-zone contact rate. The plate discipline was evident as well by a 21 percent chase rate.

The power gains were also real this year, as Campbell posted a 90th-percentile exit velocity of around 106 mph. He hit home runs as far as 450 feet with exit velocities north of 113 mph. He learned to elevate the ball more this year, thanks to an offseason swing change, and the home runs showed up as Campbell hit 20 in 2024.

Built like an NFL wide receiver, Campbell is an incredible athlete and leader on and off the field. He is the clubhouse presence that teams want, and given his performance in 2024, he checks nearly every box. His versatility on the field should allow him to find a spot in the Red Sox lineup as soon as opening day 2025, where he should impact the game with power and speed.

The last 2 years, Ceddanne Rafaela and Roman Anthony have been my breakout picks in Greenville. This year it's Kristian Campbell. The 21 yo was a 23 4th rd pick. High-end contact skills and developing power. This ball cleared the batters eye where its 420 deep in CF @SoxProspects pic.twitter.com/zsBGTS4K2N
