Red Sox Prospect Rankings, June 2026 Update: Greenville Drive Remain Loaded With Top Talent

It’s that time of the year again, when TalkSox updates our Top 20 prospect rankings for the Boston Red Sox. Both staff and readers voted and after tabulating the votes, the reveal of the list is now ready. The Top 20 saw some changes from the one released in May, which we will break down. While one prospect graduated, one fell off and two new additions replaced both. Let’s jump into it below.

2. Anthony Eyanson RHP AA (previously #4)
3. Kyson Witherspoon RHP A+ (previously #3)
4. Justin Gonzales OF/1B A+ (previously #5)
5. Henry Godbout 2B/SS A+ (previously #11)
6. Jake Bennett LHP MLB (40-man) (previously #7)

18. Hayden Mullins LHP AA (previously #19)
19. Johanfran Garcia C AA (previously #18)
20. Miguel Bleis OF AA (previously #16)

The list retained most of the previous Top 20 with only Payton Tolle and Conrad Cason dropping off of the list. Tolle’s removal due to his graduation from prospect status thanks to his stay in the majors with Boston, while Cason fell off after appearing in just four games in the Florida Complex League before being shut down due to injury. In his limited play time of 15 at-bats, the two-way player hit .267/.313/.733 with a double, two home runs and two RBIs as he works his way back from Tommy John surgery.

The biggest rank improvements belonged primarily to position players, as Henry Godbout and Enddy Azocar both rose six placements and broke into the top 10. Along with them, Justin Gonzales continued his rise on the list, going from 5th to 4th and Yoeilin Cespedes continued his resurgence to go from 13th to 11th.

Meanwhile, on the pitching side, Anthony Eyanson, Jake Bennett, Marcus Phillips and Hayden Mullins all improved in the rankings. Eyanson is now the 2nd ranked prospect, while Bennett rose one spot to 6th and Phillips bumped up from 9th to 7th. Mullins rose quietly from 19th on the list to 18th.

The biggest rank decreases belonged to Mikey Romero, who went from 8th down to 12th, falling out of the top 10, and Miguel Bleis, who continued to slide as he went from 16th down to 20th. Romero has seen his ups and downs in 2026, as he opened the year as one of the hottest hitters in all of baseball before a stretch of roughly six weeks where hits simply wouldn't fall. The month of May saw the infielder hit just .179/.222/.310 while striking out 20 times. The month of June has seen more positive results, as Romero looks to stay on track for the remainder of the season. Bleis, on the other hand, just can't find the consistency his talent deserves. So far on the season, he’s hitting .216/.286/.324 with eight doubles, four home runs and 19 RBIs. Much like Romero, he’s starting to heat up, having hit .257/.278/.329 in May followed by a line of .245/.333/.396 in June. For Bleis, the talent is there, it’s just a matter of having it show up each night.

The ranking continues to be dominated in two specific areas much like the previous update. Nine of the top 20 are pitchers, while half of the top 10 is comprised of pitchers even after Tolle’s graduation. Thanks to that, the new top pitching prospect is 2025 third-round pick Anthony Eyanson, who has dominated this season with a 1.00 ERA in 11 starts and 45 innings between High-A and Double-A. In that span, he’s managed to strike out 62 batters while walking just 16. The area that made up the second most on the list would be infielders with five of them including two within the top 10 (technically three if we count Gonzales’ one game at first base).

The second area that dominates this list is that once again, Greenville makes up the majority of the players on the list with eight (including six in the top 10). The High-A organization is a team that many should keep an eye on during the second half of the minor league baseball season to see what the future of the franchise might look like. Offensively, the team is led by Azocar, Cespedes and Gonzales. Godbout was also putting together a fine season before it was derailed with the need for hand surgery. Portland finished second once more with six players including the top two players on the list in Arias and Eyanson. The FCL came in third with three players including the two new additions to the list, while Worcester had two players on the list in mainstays Romero and Tyler Uberstine. Finally, Boston, who has had Bennett with them for the last couple weeks, had one lone prospect.

Let’s review the two new additions to our list to round things out.

Sadbiel Delzine, RHP (FCL Red Sox): No. 14

Delzine has shot up prospect rankings this season, as he went unlisted on not just the TalkSox list but nearly every major prospect ranking coming into 2026. That quickly changed once the FCL season began in early May, as he has put on a show with his pitching. A strong, tall right-hander, Delzine stands at a towering 6-foot-5 on the mound and still has room to grow as he enters his late teens (he won’t turn 19 until 2027). In his first taste of stateside baseball, Delzine has dominated in his seven appearances. Tossing 27 1/3 innings, he’s allowed just seven runs, six of them earned, while striking out 32 batters.

Delzine, who signed with the Red Sox in January of 2025, is already viewed as a high-upside arm throughout the system thanks to his size and athleticism that he’s shown during his time in Florida. Even before this season, the Red Sox were high on him, as the right-hander received the largest bonus of any pitcher signed by the Red Sox in their 2025 international free agent class.

On the mound, Delzine starts on the first base side of the rubber before throwing from a three-quarters arm slot. With a high leg kick and a quick arm, Delzine has shown an ability to repeat his delivery early on in his career. Thanks to his large body and the belief he’ll only grow more, Delzine has the body of a starter and will be developed as such.

He already has a four-pitch arsenal, with three of them already in game-ready form. His best pitch is his fastball, while he uses a changeup and curveball to supplement it. Delzine also has a slider, but it’s behind his other two secondaries. The fastball averages around the low-90s, topping out as high as 94 mph at times and is viewed as having room to add velocity as he grows. Despite being his best pitch so far in his career, it might be his changeup that becomes his best pitch in the future thanks to the bat-missing ability it’s already showcasing.

His curveball is one that breaks 11-to-5 and some have said that at its best, it showcases a tight rotation that allows him to bury it down in the zone and can throw it away from right-handed batters. There isn’t much on his slider, as it’s still being developed.

Overall, he’s viewed as a high-upside prospect that should be able to handle the strain of starting games along with having the mental aspect needed due to his competitive nature. Should Delzine develop consistently and avoid injuries, there may be a new arm joining the likes of Eyanson, Witherspoon and Phillips when it comes to the most hype in the system.

Franklin Primera, C (FCL Red Sox): No. 17

Whereas Delzine was signed in January of 2025, Primera was signed by the Red Sox out of Venezuela in September of 2024 and was sent to the Dominican Summer League in 2025 at the age of 18. The young catcher immediately dominated the league, as he slashed .333/.465/.430 with 10 doubles, one home run and 27 RBIs while being added to the All-Star Game as an injury replacement. Primera would go on to win the game’s MVP after hitting a home run in his lone at-bat.

Following his great season, the team had him play in the 2026 Spring Breakout game along with being on the roster for their annual Futures at Fenway South game. The team then decided he was ready for the FCL and had him open the season in Florida instead of spending more time in the DSL. Through his first 27 games this season, Primera has made that decision look smart, as he’s hit .464/.589/.821 with six doubles, eight home runs and 28 RBIs all while playing outstanding defense.

Measured at 6-foot-0, Primera still has some room to grow, especially in his upper body, but he should manage to stick behind the plate without worry about his size. He does, however, need to get stronger if he wants to improve various aspects of his game.

As a hitter, Primera has a compact swing that is short and allows him to find the barrel consistently. However, he does not see many pitches as he will look to attack early in the count, something that more advanced pitchers could take advantage of as he moves up the minor-league levels. He will need to work on developing how he attacks pitchers along with recognizing different pitches. He has pull-side power, but if he wants to really tap into it, he’ll have to add strength so that he can impact the ball with higher exit velocities. His speed is well below average, however, and should not be viewed as a part of his game.

Defensively, he is strong and should remain behind the dish barring a major injury. His ability to block baseballs in the dirt is great thanks to his ability to move well behind the plate. He also has plus receiving and framing skills despite being just 19 years old. His arm is also viewed as above average and should only increase as he improves his strength and conditioning.

Overall, there’s a lot to like about Primera, as his defensive upside alone should give him a quicker path to the majors than most backstops. His ceiling and floor will all be based on how his hit tool develops, and he could either be a serious catching prospect or nothing more than upper-minors depth. Despite that, the Red Sox have a fun prospect to keep an eye on for the next couple seasons as the organization tries to figure out what they have in their catching department.
