Red Sox
Even after the promotions of Roman Anthony and Marcelo Mayer, Boston’s farm system is showing promise.
The arrival of several blue-chip prospects up at the big-league level has been one of the top storylines drawn from the 2025 Red Sox season so far.
Top prospects Roman Anthony, Marcelo Mayer, and Kristian Campbell have earned reps up in The Show, while catcher Carlos Narvaez has arguably been Boston’s most impressive rookie so far this year.
Those respective call-ups represent the long-awaited influx of one of the most promising prospect groupings in Red Sox history.
But even if Boston’s farm system is expected to take a hit now that players like Anthony and Mayer are playing for Boston, the Red Sox’s farm system is far from barren moving forward.
Here are six other Red Sox prospects to following moving forward this season and beyond:
Franklin Arias, SS (Greenville Drive)
Arias might still be a few summers away from establishing himself as an impact player in Boston. But the 19-year-old infielder has seen his stock soar in recent months, putting him on the map as the Red Sox’s latest can’t-miss prospect.
While names like Anthony, Mayer, and Campbell dominated discourse regarding Boston’s farm system, Arias was ranked No. 42 overall by The Athletic’s Keith Law in his preseason 2025 rankings of the top prospects in baseball.
In late May, Law ranked Arias as the No. 8 prospect in all of baseball — a significant leap for a player who has not earned a promotion beyond High-A ball yet in his young career.
“Leave it to the Red Sox to graduate a top-10 prospect (Kristian Campbell) and immediately have someone else replace him,” Law wrote.
The 5-foot-11 Arias was signed by the Red Sox out of Venezuela as an international free agent in 2023. At the time, he was deemed a plus defender at the position whose ceiling at the pro level would revolve around how much he could improve his hit tool.
So far, Arias has continued to take steps forward at the plate with High-A Greenville, batting .305 over 41 games with 11 doubles, four home runs, 27 RBI, and five stolen bases.
Even with his inexperience, Arias has already displayed promising plate discipline with just 15 strikeouts across 169 at-bats with Greenville.
“Arias was the MVP of the Florida Man League last year at age 18, then ended with a credible .257/.331/.378 line in 36 games in Low A to finish his first season playing in the U.S,” Law wrote. “He went back to Low A and was so good the Red Sox bumped him up to High A before April was out.
“He hasn’t stopped hitting since, with exceptional contact skills and breaking ball recognition already. He has whiffed on just 10 percent of the pitches he’s swung at this year, which would be great for pretty much any player but is wild for a player who’ll be 19 all season, playing in High A. … We’re looking at a shortstop with a plus hit tool and 20-plus homer upside. That’s a prospect who ends up in the running to be No. 1 at some point.”
The Red Sox would welcome such a scenario playing out with Arias supplanting Anthony as another No. 1 prospect in the system.
Jhostynxon Garcia, OF (Worcester Red Sox)
Garcia is already a name to watch given his popular nickname (“The Password — as featured on Jeopardy!).
But the 22-year-old outfielder is also not showing any signs of slowing down since getting promoted to Triple-A Worcester in late May. Since then, the Venezuelan product is batting .311 with eight home runs and 19 RBI over 27 games.
An unranked prospect on Law’s initial preseason rankings, Garcia slotted in at No. 46 overall on his updated list in May shortly after getting the call up to Worcester.
“The Password, as he is known, has taken a pretty significant step forward this year off a breakout year in 2024,” Law wrote. “He’s swinging less often, which has also meant that he’s whiffing less and he’s chasing less, and he’s still hitting the ball hard — although the surface results haven’t been there yet.
“The Red Sox bumped him up to Triple A last week and in his first six games there he homered twice, at 106 and 109 mph. It’s plus power, a significantly improved approach, and, well, he should move to right field.”
Boston’s outfield is already crowded between the likes of Jarren Duran, Anthony, Wilyer Abreu, and Ceddanne Rafaela. But, Garcia’s continued offensive surge stands as another good problem to have for the Red Sox and their future plans in the outfield.
Payton Tolle, P (Greenville Drive)
The Red Sox have no shortage of potential impact position players in place up at the big leagues.
But, developing premier pitching talent has often been an arduous undertaking for the Red Sox.
Boston is banking on Tolle changing some of that sentiment, with the 6-foot-6, 250-pound southpaw already putting together strong returns in High-A ball.
Drafted in the second round (50th overall) of the 2024 MLB Draft out of TCU, Tolle was the earliest the Red Sox had selected a pitcher in the draft since Tanner Houck (24th overall) in 2017.
Even though his ERA in Greenville (3.62) may not turn heads, the Red Sox have been pleased with his uptick in velocity and swing-and-miss stuff — as he’s already struck out 79 batters across just 49.2 innings of work with 14 walks.
He might be a few years away, but there’s a lot to like about his stuff on the mound.
“The fact that he’s sitting 95 up to 98 [miles per hour], did not expect that Year 1. We expected that maybe Year 2 or Year 3, but the trajectory he’s taken is pretty special, Red Sox director of pitching Justin Willard told The Boston Globe’s Alex Speier last week of Tolle’s velocity”. Now it’s just continue to refine the other things around what he’s doing.”
Brandon Clarke, P (Greenville Drive)
Much like Tolle, Clarke is another imposing southpaw with plus stuff on the mound.
Taken in the fifth round of the 2024 MLB Draft, Clarke has been impressive during his limited reps so far with Greenville, sporting a 2.51 ERA and striking out 21 batters over just 14.1 innings of work.
Clarke, who is 6-foot-4 and 220 pounds, is averaging 97 miles per hour on his fastball and also possesses a cut fastball with a 74 percent rate, per Speier.
“The ceiling is through the roof,” Willard told Speier of Clarke’s potential. “We’re really focused on that with him.”
One thing worth monitoring with Clarke is his health, as he hasn’t pitched since May 24 due to a blister issue.
James Tibbs, OF (Portland Sea Dogs)
Kyle Harrison, 23, might offer the highest upside for Boston among the players acquired as part of last week’s shocking trade centered around Rafael Devers.
But even though he’s currently working on his craft with Triple-A Worcester, Harrison has plenty of big-league reps under his belt already (182.2 innings).
Tibbs stands as the top prospect that Boston gained in the Devers’ trade, as he was ranked as San Francisco’s No. 3 overall prospect by Baseball America.
Tibbs was selected No. 13 overall in the 2024 MLB Draft — just one spot after the Red Sox selected Texas A&M outfielder Braden Montgomery at No. 12 overall. Montgomery was later traded by Boston as part of the package to acquire Garrett Crochet from the White Sox in December 2024.
A 22-year-old outfielder with some pop, Tibbs was batting .246 with 12 homers, 10 doubles, one triple, 32 RBIs, 41 runs, 42 walks and 45 strikeouts in 57 games for High-A Eugene this season before the trade.
He has started his Red Sox career up in Double-A Portland, batting .263 with a double, triple, and two RBI over five games.
“Potential bat-first platoon outfielder,” SoxProspects.com said of Tibbs’ big-league profile. “Lacks a standout tool, but could get to average hit and power.
“Checks a lot of boxes the Red Sox look for in hitting prospects and they were reportedly interested in him in the 2024 draft. Hits the ball hard and makes good swing decisions, but could stand to show more consistency against off-speed and contact ability against velocity.”
Blaze Jordan, 1B/3B (Worcester Red Sox)
Jordan has been in Boston’s system for years now, but the 2020 third-round pick seems to have his stock soaring at just the right time.
With Triston Casas out for the season and Devers now in San Francisco, the Red Sox are still in desperate need for a stable option at first base.
It just so happens that the 22-year-old Jordan is now playing the best baseball of his career since getting called up to Triple-A Worcester earlier this month. Over 17 games with the WooSox, Jordan is batting .329 with 11 extra-base hits and 12 RBI over 17 games.
As noted by MassLive’s Chris Smith, Jordan has also not committed an error at both first base and third base all season long between Portland and Worcester.
The Red Sox might target an established big-leaguer at the trade deadline if they want to add depth to the infield. But Jordan is making a pretty compelling case for himself over the last few weeks.
