Boston Red Sox fans are hard-pressed to find something to cheer about amid the club’s woeful 13-21 start to the 2026 season. While it won’t help the team turn things around any time soon, Boston’s farm system is worthy of some applause.
Even with former top prospects Roman Anthony and Marcelo Mayer no longer in the mix, the Red Sox’ prospect pipeline is in solid shape. Young left-handers Payton Tolle and Connelly Early headline a system filled with exciting pitching talent. Three of their top 10 prospects — Kyson Witherspoon, Anthony Eyanson and Marcus Phillips — were selected in last year’s MLB Draft.
While the system is lighter on position player prospects than recent years, there’s still some intriguing talent there as well. Franklin Arias has developed into one of the best infielder prospects in the game, while 19-year-old behemoth Justin Gonzales continues to mash in High-A.
Here’s a closer look at the top 10 Red Sox prospects (via SoxProspects.com):
1. Payton Tolle, LHP
2026 stats: 2-0, 3.00 ERA, 1.067 WHIP, 4 BB, 19 SO (three starts at Triple-A Worcester); 0-1, 3.38 ERA, 5 BB, 15 SO (two starts for Boston)
Tolle is back with the big-league club after opening the 2026 season at Triple-A Worcester. The 23-year-old southpaw started last season at High-A and finished in MLB, but he experienced some growing pains during his brief stint in the majors.
After veteran Sonny Gray was placed on the injured list in April, Tolle took his spot in the rotation and immediately showed why he’s the unquestioned No. 1 prospect in this system. He struck out 11 Yankees hitters while allowing only one run on three hits over six innings in his season debut.
Tolle wasn’t as sharp in his second start, and his velocity dipped significantly. His fastball is elite when he’s on, but he’s still figuring out how to utilize his secondary pitches
When Gray returns, Tolle could be sent back down to Worcester to continue his development into one of the game’s most exciting young pitchers. He’ll make his third MLB start of the season Monday night in Detroit, so it’ll be interesting to see which version of Tolle shows up.
2. Franklin Arias, SS
2026 stats: .359/.433/.731, 8 HR, 20 RBI, 7 BB, 10 SO (22 games at Double-A Portland)
MLB ETA: Late 2026
To say Arias is tearing it up in Portland would be an understatement. The 20-year-old has unlocked his power this season, mashing eight homers in 22 games — just one fewer HR than his previous high of nine in 87 games between rookie ball and High-A in 2024.
With this power surge, Arias is making a name for himself not only as one of Boston’s most intriguing prospects but also one of the most exciting young talents in MLB. He always had the above-average hit and fielding tools, but his power takes his potential to another level.
At this rate, we could see Arias earn a quick promotion to Worcester. And given how the big-league club has performed this season, it wouldn’t be that surprising to see him debut later this year if it wants to give fans something to be excited about.
3. Connelly Early, LHP
2026 stats: 2-2, 3.79 ERA, 1.318 WHIP, 17 BB, 31 SO (seven starts for Boston)
Early is coming off his worst start of the season, but the rookie southpaw has otherwise been a breath of fresh air for a disappointing Red Sox rotation. He has the second-best ERA in the group behind Ranger Suarez, as well as the third-most strikeouts behind Suarez and Garrett Crochet.
Going forward, Early will look to cut down on walks and homers allowed. His walk rate (4.3 percent) is the highest of his professional career, and he has already let up five long balls. He allowed five homers all of last season between Triple-A and MLB (21 games).
4. Kyson Witherspoon, RHP
2026 stats: 0-2, 7.13 ERA, 1.868 WHIP, 12 BB, 20 SO (five starts at High-A Greenville)
MLB ETA: 2027
Entering this season — Witherspoon’s first as a pro — some believed the Oklahoma product could debut with Boston at some point in the campaign. Sooners head coach Skip Johnson told us he wouldn’t be surprised to see the 2025 first-round pick take the big-league mound as soon as 2026.
Through his first five starts at High-A, it’s clear that he’ll need more time to develop. While the 21-year-old has filthy stuff, command has been an issue. That should improve with time, as it did during his college career.
5. Juan Valera, RHP
2026 stats: 0-0, 1.93 ERA, 0.857 WHIP, 4 BB, 17 SO (three starts at High-A Greenville)
MLB ETA: 2028
The good news? Valera is a 19-year-old freak of nature who hit 102 mph on his fastball early this season. The bad news? He left his most recent start with an elbow inflammation and is reportedly seeking a second opinion from outside the Red Sox organization.
We should hear more on the severity of Valera’s injury in the coming days, but it doesn’t sound promising. He missed three months with an elbow injury last season.
Injury aside, Valera is a joy to watch take the mound with his overpowering stuff. He worked his way into Baseball America’s Top 100 rankings just before his latest setback.
6. Anthony Eyanson, RHP
2026 stats: 0-0, 0.44 ERA, 0.492 WHIP, 3 BB, 34 SO (five starts at High-A Greenville)
MLB ETA: 2027
With Tolle and Early set to graduate from prospect status soon, Witherspoon struggling, and Valera hurt, Eyanson is the Red Sox pitching prospect you need to start paying attention to if you haven’t already.
A third-round pick out of LSU in 2025, the 21-year-old has put up video-game numbers over five High-A starts. He has already earned himself a promotion to Double-A one month into his pro career. To put that in perspective, he was promoted to Double-A seven weeks earlier than Tolle was last season, and Tolle finished the year in the bigs.
If Eyanson continues at anything close to his current pace, he should follow a similar path.
7. Marcus Phillips, RHP
2026 stats: 0-1, 5.87 ERA, 1.565 WHIP, 12 BB, 20 SO (Five appearances, four starts at High-A Greenville)
MLB ETA: 2028
Phillips was selected in the first round (33rd overall) of the 2025 draft. The Tennessee product’s ERA and walk rate show he still has plenty of work to do at High-A, but his high strikeout rate (11.7 K/9) is evidence of his filthy stuff. The 21-year-old boasts an impressive arsenal with an above-average fastball, cutter, and slider.
Like fellow 2025 first-rounder Witherspoon, Phillips has a high ceiling and is on track to one day become a top-of-the-rotation arm.
8. Justin Gonzales, RF
2026 stats: .302/.385/.500, 4 HR, 18 RBI, 8 BB, 18 SO (22 games at High-A Greenville)
MLB ETA: 2028
Other than Arias, Gonzales is the most fun position player to watch right now in Boston’s farm system. The 19-year-old has raw power at 6-foot-5, 270 pounds. The hit tool was a question mark entering this season, but he has quelled those concerns with a .302 batting average through 22 games.
Gonzales’ four homers don’t do his power justice. He consistently posts exit velocities above 100 mph; he just needs to continue working on elevating the ball more to get it over the fence. Remember: he’s only 19. With his size and strength, Gonzales should develop into one of the game’s most feared power-hitting prospects.
9. Dorian Soto, SS
2026 stats: .167/.444/.167, 0 HR, 0 RBI, 3 BB, 3 SO (Two games at Florida Complex League)
MLB ETA: 2029
The Red Sox signed Soto as an international free agent in 2025. The 18-year-old Dominican Republic native has tremendous offensive upside, though he has yet to display his true power potential with the Red Sox organization. He hit only two homers in 47 rookie-ball games last season.
That said, the switch-hitting Soto has an advanced approach at the plate for his age. His second pro season just got underway in the FCL, so we’ll surely see plenty of Soto highlights in the coming weeks.
10. Jake Bennett, LHP
2026 stats: 2-1, 0.86 ERA, 0.714 WHIP, 3 BB, 16 SO (Five starts at Triple-A Worcester); 1-0, 1.80 ERA, 1.40 WHIP, 2 BB, 3 SO (One start for Boston)
MLB ETA: 2026
The Red Sox acquired Bennett from the Washington Nationals during the offseason in exchange for fellow top pitching prospect Luis Perales. The 25-year-old southpaw impressed in five Triple-A starts before making his big-league debut Friday against the Houston Astros at Fenway Park.
Bennett won’t wow anyone with his stuff. His fastball sits in the 92-95 mph range, and his breaking pitches aren’t anything to write home about. He does have an above-average changeup that yields swings and misses, and with his elite extension, his fastball/changeup combo has been enough to find success at a high level. His ability to throw strikes is also a huge plus.
