Red Sox prospect update: Franklin Arias hype train is still rolling originally appeared on NBC Sports Boston
Do the Boston Red Sox have their shortstop of the future in top prospect Franklin Arias?
If that question prompted an eye roll, we understand. We asked the same question when Marcelo Mayer was in Boston’s farm system, and the No. 4 overall draft pick hasn’t yet lived up to his lofty expectations in the majors. While Mayer has been an outstanding defender wherever he’s been asked to play on the infield, his bat has been a disappointment.
There’s reason to believe Arias will be different. Throughout his minor-league career, Mayer never had the numbers that Arias is putting up this season. Left-handers have always given Mayer trouble, but Arias has hit well against both lefties and righties.
It shouldn’t be long before Arias is promoted to Triple-A, and we shouldn’t rule out a potential MLB debut later this year. Here’s a closer look at how he and the rest of the Red Sox’ top 10 prospects (via SoxProspects.com) have fared so far in 2026:
1. Payton Tolle, LHP
2026 stats: 2-0, 3.00 ERA, 1.067 WHIP, 4 BB, 19 SO (three starts at Triple-A Worcester); 2-2, 2.61 ERA, 0.90 WHIP, 11 BB, 46 SO (seven starts for Boston)
Tolle has been excellent so far in his second stint with the big-league club. The 23-year-old has been one of Boston’s most consistent arms since being called back up last month, so it shouldn’t be long before he graduates from these prospect rankings and becomes a mainstay in the rotation.
As good as Tolle has looked, he’ll be even better once he takes the next step with his off-speed stuff. He threw 54 four-seam fastballs, 26 sinkers, and 11 cutters with only two curveballs and one changeup during his most recent start vs. the Atlanta Braves.
The sky is the limit for Tolle if he can start getting hitters off balance with his secondary pitches.
2. Franklin Arias, SS
2026 stats: .331/.402/.624, 12 HR, 31 RBI, 15 BB, 22 SO (41 games at Double-A Portland)
MLB ETA: Late 2026
Franklin Arias has done nothing but rake this year in Portland. The 20-year-old wasn’t known for his pop before this season, but he has already set a new career high with 12 homers while keeping his OPS above 1.000.
MLB prospect evaluators have taken notice, including Keith Law of The Athletic. Law put Arias at No. 3 in his top 50 MLB prospects list.
While it’s Arias’ power that has helped him earn national recognition, his plate discipline remains elite. He’s struck out only 22 times with 15 walks in 179 plate appearances. In the field, he still looks like a future Gold Glove shortstop.
It probably won’t be long before Arias earns his promotion to Triple-A, and if all goes well there, we could see him debut in the majors later this year.
3. Anthony Eyanson, RHP
2026 stats: 1-0, 1.35 ERA, 0.660 WHIP, 9 BB, 50 SO (five starts at High-A Greenville; three starts at Double-A Portland)
MLB ETA: 2027
Eyanson was promoted to Double-A Portland after dominating in his five starts at High-A Greenville. The 2025 third-round pick out of LSU has stayed sharp with the Sea Dogs to earn the No. 21 spot in Law’s top 50 prospects list.
Eyanson, 21, is rising through the minor league ranks even quicker than Tolle did in 2025. He also has a more complete arsenal than Tolle with a high-90s fastball, a wipeout slider, a killer 12-6 curveball, and a splitter he has utilized more recently and found success with.
If he continues to perform at this level, Eyanson could get the Tolle treatment and join the MLB club sometime in the second half.
4. Kyson Witherspoon, RHP
2026 stats: 0-3, 5.55 ERA, 1.542 WHIP, 21 BB, 36 SO (nine starts at High-A Greenville)
MLB ETA: 2027
Witherspoon’s first professional season probably hasn’t gone the way that he hoped. The first-round pick out of Oklahoma has struggled with his command through his first nine starts at Single-A, though it appears he’s turning a corner.
Over his last two starts, Witherspoon has allowed just one earned run across 9.1 innings pitched. He struck out 10 hitters in that span, including a six-K performance with 19 whiffs on May 24:
Witherspoon still has the ceiling of a future top-of-the-rotation arm. If he builds off his last two starts and improves his command, that All-Star potential should be on display throughout the second half of his season.
5. Marcus Phillips, RHP
2026 stats: 0-3, 9.00 ERA, 1.958 WHIP, 20 BB, 29 SO (Eight appearances, seven starts at High-A Greenville)
MLB ETA: 2028
Like Witherspoon, Phillips has struggled with his command and has yet to showcase his potential in the pros. The 33rd pick in the 2025 draft has walked an alarming 7.5 batters per nine innings this season. He had control issues while at Tennessee as well, so this isn’t totally surprising.
Phillips is a physical specimen at 6-foot-4, 250 pounds. He has impressive stuff, including a high-90s fastball and a wipeout slider that generates plenty of whiffs. There’s a lot to be excited about with the 21-year-old despite his less-than-ideal start.
6. Jake Bennett, LHP
2026 stats: 3-2, 1.83 ERA, 1.049 WHIP, 6 BB, 37 SO (Eight starts at Triple-A Worcester); 1-1, 4.35 ERA, 1.452 WHIP, 4 BB, 4 SO (Two starts for Boston)
Bennett made his big-league debut on May 1, allowing just one run over five solid innings against the Houston Astros. His second outing didn’t go as well, as he let up four runs in 5.1 IP.
Still, Bennett proved that he’s a more-than-servicable starter when Boston’s rotation needs reinforcements. The 25-year-old’s stuff isn’t what anyone would call electric, but he has found a way to fool hitters and put up impressive numbers in Worcester:
7. Justin Gonzales, RF
2026 stats: .287/.371/.480, 7 HR, 27 RBI, 17 BB, 31 SO (40 games at High-A Greenville)
MLB ETA: 2028
The 6-foot-5, 270-pound Gonzales continues to impress in Greenville. The 19-year-old has eight doubles and two triples to go with his seven homers so far this season, and he still hasn’t unlocked his full potential at the plate.
Once Gonzales learns to elevate the ball more consistently, he’s going to be a problem. At his age, with his raw power and impressive hit tool, he might be the most exciting hitter in Boston’s system. He’ll be fascinating to watch as he rises through the minor-league ranks.
8. 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 19-year-old Valera was one of Boston’s most hyped prospects heading into the season. He reached 102 mph with his fastball while posting impressive numbers across three High-A starts, but he suffered a devastating elbow injury that required Tommy John surgery.
Valera had earned a spot in Baseball America’s Top 100 before his injury.
9. Dorian Soto, SS
2026 stats: .254/.315/.299, 0 HR, 5 RBI, 6 BB, 19 SO (17 games at Florida Complex League)
MLB ETA: 2029
Soto has gotten off to a slow start this season in rookie ball. While the 18-year-old Dominican has exciting upside at the plate, he tallied only two homers last year and has yet to hit one over the fence through 17 games this season.
This shouldn’t be a concern. The switch-hitting Soto remains one of Boston’s most exciting young talents, and it’s just a matter of time before he starts to put it all together.
10. Henry Godbout, SS
2026 stats: .277/.410/.492, 7 HR, 14 RBI, 22 BB, 27 SO (34 games at High-A Greenville)
Before the season, prospect expert Ian Cundall of Baseball America identified Godbout as a breakout candidate for 2026. The second-round draft pick out of Virginia has lived up to the hype.
Godbout has continued to showcase his impressive hit tool, and his power has been a positive development. The 22-year-old maxed out at nine homers with Virginia and already has seven through 34 games at High-A.
The bat-to-ball skills are already elite. If the power is here to stay, Godbout should rapidly ascend through the minors:
