1. Franklin Arias
After top infield prospects Marcelo Mayer and Kristian Campbell graduated from Boston’s system in 2025, Franklin Arias took hold of the being the most promising infield prospect for the Red Sox. Arias made quick work of the lower levels of pro ball before advancing to Double-A Portland at the end of last season, being the only teenager in Boston’s system to reach Double-A, and was one of just nine players 19 years old or younger across all organizations to reach Double-A in 2025. Arias’s game starts with the advanced hit tool. He struck out only 10.1% of the time across 526 plate appearances last year between Double-A, High-A Greenville, and Low-A Salem. It’s an aggressive approach that leads to lower walk rates and less optimal contact quality, but there’s some power projection in his future that might mitigate some chase risk. Defensively, Arias is going to stick up the middle, whether it be at shortstop or second base. He has good instincts and actions along with a strong enough arm to stick at short, but he might give way to a more athletic defender in the future, sliding over to second base where he could be a plus defender. Arias has average speed on the bases that hasn’t played as well as it did in the lower levels of the minors as he stole only 12 bases across 116 games in 2025 compared to 35 across 87 games in 2024.
2. Kyson Witherspoon
Kyson Witherspoon was the second highest college right-handed pitcher selected in last year’s draft, and he enters a pretty favorable system considering Boston’s success with pitchers as of late. The 6’2”, 205 pound right-hander spent his sophomore and junior seasons at the University of Oklahoma where he stuck out 31.8% of the batters he faced while walking just 5.9% in 2025. He features a wide arsenal with solid pitch-ability, throwing a fastball, slider, curveball, cutter, changeup, and a sweeper in which he added during the off-season. The fastball sits in the mid-90s, reaching as high as 99 mph in college, although it lacks in shape. He can really spin both his slider and curveball, with his curve getting a lot of downer action while his slider works on a tighter two-plane shape. His cutter is arguably his best pitch, featuring a bullet or gyro slider shape and working in the high-80s to low-90s. He flashed the new sweeper in bullpens over the winter, featuring up to 20 inches of horizontal break. Witherspoon stands out for his elite athleticism which helps to project above-average command at the pro level. He has yet to make his professional debut, but he could join a handful of Red Sox pitching prospects that flew through the system given his high floor as a starter.
3. Justin Gonzales
Although it has yet to show up on a stat line over the course of a full season, Dominican product Justin Gonzales has arguably the highest ceiling among any prospect in Boston’s system. It all starts with the physicality for the right-handed hitting outfielder. He just turned 19 years old but already looks the part of a big league ballplayer, coming in at a very strong 6’4” and 210 pounds. The strength is evident at the plate as it’s a violent right-handed swing with impressive bat speed. He has only hit nine home runs in 140 career games at the Minor league level, but once he starts optimizing his batted ball profile as he continues maturing physically, expect that number to take off. With a player of Gonzales’s size and power profile, you would expect some swing and miss, however, Gonzales has actually posted some above-average contact numbers for his level. He had a 15.9 K% in 410 plate appearances between the Complex League, Low-A, and High-A in 2025 while it was a 10.4 K% at the Dominican Summer League in his first taste of pro ball in 2024. He can struggle with expanding the zone, but the contact skills and power projection help to mitigate the chase. An average athlete and runner at best, Gonzales might end up at first base long-term if the Red Sox really want to lean into what the bat may provide. However, Gonzales has stuck around in the outfield in his young career and actually played the majority of his games in 2025 in center field where he features plus arm strength. Gonzales was the only player 18 years old or younger in Boston’s system to reach High-A in 2025 and was one of eight players across all organizations to do so.
4. Dorian Soto
The top prospect in Boston’s 2025 international signing class, Dorian Soto is one of the toolsier Red Sox prospects for his age. Soto signed a month before his 17th birthday and just turned 18 ahead of the 2026 season. He spent all of 2025 at home at the Dominican Summer League where he played 47 games and posted a .307/.362/.428 slash line, with two home runs, good for a 106 wRC+. A switch-hitter, Soto blends a solid hit tool with projectable power at 6’2” and 180 pounds. He’s a platoon-neutral switch-hitter, although he saw some more success as a lefty, owning a .736 OPS as a right-handed hitter and an .804 OPS as a left-handed hitter in 2025. Soto will stick around as an average shortstop defender for the foreseeable future, but may slide over to third base as he may outgrow shortstop and possesses a strong arm that will play in the corner just fine.
5. Anthony Eyanson
The 87th overall pick in last year’s draft, Eyanson was the third of three right-handed SEC pitchers selected by the Red Sox with three of their first four picks. The 6’2”, 210 pound LSU product was the number two on the College World Series winning LSU squad a year ago, so he brings a lot of high-leverage experience against some of the top talent amateur baseball has to offer with him into Boston’s system. A premier athlete on the mound, Eyanson stands out for his command and pitch-ability over his stuff, although the stuff is pretty good too. His slider is his best pitch which he can really spin and locate both inside and outside of the strike zone in the mid-80s for called strikes and whiffs. He works in a upper-70s curveball that flashes plus as well, featuring a low of downer break. His low-80s changeup is still a work in progress as he was able to lean heavily on the breaking offerings in college. The shape on his mid-90s fastball is fringy, but it has reached as high as 98 mph and he commands it well. Eyanson walked just 8% of batters he faced last year while striking out 33.9%. He has the makings of a middle of the rotation starter, but that will depend on the development of his arm-side offerings.
6. Juan Valera
A member of Boston’s 2023 international signing class, Juan Valera is among a number of Red Sox pitching development successes to this point in his career. Not very highly touted coming out of the Dominican Republic, Valera broke on to the scene at the age of 18 after coming state side in 2024. Between the Complex League and Low-A, he posted a 27.9 K% and a 0.85 WHIP while opposing batters hit just .123 off the 6’3”, 205 pound right-hander. He spent all of 2025 at High-A where his results backed up but where he also showed improved command, lowering his walk rate by 5.5%. Had it not been for an injury that sidelined him for a few months in the middle of the season, Valera might have seen some time at Double-A in 2025 at the age of 19. Valera works primarily with a fastball and a slider, both of which flash plus. The fastball sits in the mid to high-90s, touching triple digits occasionally. He can mix in a 2-seam alongside it as well. The slider is arguably his best pitch, working in the upper-80s with sweeping action, a really unique look for hitters. He hasn’t shown much with a changeup, so his 2-seam is the closest thing he has to an effective offspeed pitch. Valera comes with some reliever risk, so a number of things will have to go right for him to be a legitimate rotation piece at the big league level - specifically the development of an offspeed pitch and command that holds up in the upper levels of the minors.
7. Marcus Phillips
The Red Sox second selection in last year’s draft, Phillips fit the mold of what the Red Sox targeted throughout the entire draft - big, physical college arms. Phillips comes in at a strong 6’4”, 245 pounds, showcasing a true starter’s frame. He’s an imposing figure on the mound, exploding off the rubber with extension and power and also creating some deception with a lower arm slot. It’s a three pitch mix, a fastball, slider, and changeup. The fastball has touched triple digits and sits in the mid to high-90s but lacks some shape. The slider sits in the mid-80s and has more sweep than depth. His offspeed pitch has the potential to be his best offering - “offspeed” because it doesn’t fit in the changeup or splitter bucket, but rather is more like a splinker, featuring a lot of arm-side run and sits in the low-90s. Command of Phillips’s arsenal will be the biggest developmental question for the Tennessee product. His walk rate last year was 9.5%, down from 16.3% in his freshman year, so there was some improved control, but the decrease in free passes was also due to the undisciplined nature of a number of college hitters.
8. Mikey Romero
Mikey Romero’s development has been a slower process than a number of top Red Sox prospects, but he still has as good a shot at being an impactful piece on the big league roster at some point. Boston’s first round pick in 2022, Romero got his first taste of Triple-A Worcester late in 2025. He hit a career high 17 home runs in 111 games between Double-A and Triple-A, and although it seems like he has been around for a long time, he did that in just his age 21 season, and just turned 22 earlier in the year. Romero’s offensive production starts with the game power. He doesn’t have plus raw power but makes the most of the juice he does have by driving balls in the air to the pull-side while showing some doubles power in the gaps. There are certainly some holes in the hit tool as he struck out a total of 27% of the time in 2025 and 30.2% of the time in 192 plate appearances at Triple-A, but some of the increase in his strikeout rates this year can be contributed to him deploying a more aggressive approach to tap into the pull-side pop. Defensively, Romero is likely better suited for second base long-term due to his average arm strength, but he has the athleticism and instincts to cover shortstop or third base in a pinch at the big league level.
9. Miguel Bleis
A few weeks before his 17th birthday, the Dominican product Miguel Bleis inked the highest signing bonus by a Red Sox prospect in the 2021 international signing class. He has had a hard time living up to the hype he brought into the system, but there are still a number of tools that show promise for Bleis who is about to turn 22. The 6’0”, 170 pound outfielder is one of the premier athletes in Boston’s system, blending power, speed, and defense into his profile. His defense in the outfield is likely his best tool, featuring excellent range and a strong arm. He played primarily center field in the lower levels of the minors, but split time between center and right in 2025. His speed that he puts to use in the outfield is evident on the bases as well as he stole 27 bases in 2025 and 38 a year prior. He has the chance to show some real game-changing power, however, he has had a hard time tapping into it due to the holes in his hit tool. His chase rates are the more concerning part of the equation, but he can struggle with in-zone swing and miss as well. Regardless, he was still able to hit a career-high 14 home runs in 2025 and still has time to iron out the approach as he continues to get bigger and stronger.
10. Jake Bennett
Coming over from the Nationals in the Luis Perales trade over the winter, Jake Bennett slots in as the top left-handed pitching prospect in Boston’s system following the debuts of Peyton Tolle and Connelly Early. Bennett turned 25 late last year and advanced as high as Double-A Harrisburg in Washington’s system. Had it not been for an elbow injury that sidelined Bennett for the entirety of 2023, it’s likely he has already made his big league debut by now. Prior to the injury, Bennett was flashing some above-average stuff, but has had a hard time taking his stuff to the next level since. However, what he lacks in stuff, he makes up for with a wide pitch mix and solid command as well as some outlier release traits. He gets down the mound well from the left side, producing elite extension and also gives hitters a unique look with a lower release point. He throws a 4-seam and sinking fastball shape, both of which sit in the low-90s. His breaking pitches are fringy, but play up when he’s mixing them in with his mid-80s cutter. His mid-80s changeup is often regarded as his best pitch, featuring depth and arm-side run. Bennett has worked primarily as a starter throughout his pro career, but might fit better in a long-relief or a bulk role at the big league level.
