Red Sox promote pitching prospect Sadbiel Delzine to Low-A Salem

With the 2026 Florida Complex League regular season ending later this week, the Red Sox promoted teenage pitching prospect Sadbiel Delzine to Low-A Salem on Tuesday.

Delzine is moving up to full-season ball after a strong start to his first campaign stateside. The 18-year-old right-hander posted a 2.72 ERA with 43 strikeouts to 18 walks over 11 outings (seven starts) spanning 39 2/3 innings for the rookie-level FCL Red Sox. Opposing hitters slashed just .170/.282/.199 across 163 plate appearances against him.

Among the 27 pitchers who entered Tuesday having thrown at least 35 innings in the Florida Complex League this season, Delzine ranks first in FIP (3.71), second in batting average against and WHIP (1.06), fifth in ERA, sixth in strikeout rate (26.4%), ninth in walks per nine (4.08), 11th in walk rate (11%), and 13th in strikeouts per nine (9.76) and xFIP (5.07), according to FanGraphs.

Delzine is currently ranked by Baseball America as Boston’s No. 11 prospect, placing fourth among pitchers in the organization. The native Venezuelan originally signed with the Red Sox for $500,000 as a highly-touted international free agent in January 2025. He made his professional debut shortly thereafter, but was limited to just three starts and 9 1/3 innings in the Dominican Summer League last season due in part to flexor tightness.

After working to strengthen his shoulder over the offseason, Delzine has experienced an uptick in velocity this year. The 6-foot-5, 255-pound righty features an upper-90s fastball that has topped out at just below 100 mph. He is also capable of mixing in a curveball “with depth,” a slider “that tunnels well off his fastball,” and a changeup “that dives to the arm side,” per his Baseball America scouting report.

Having last pitched on July 17, Delzine — who does not turn 19 until January — could make his Low-A debut as soon as the latter half of Salem’s home series against Augusta this weekend. He joins catcher Franklin Primera and infielder Louis Andujar as notable Red Sox prospects who have joined the RidgeYaks from the Florida Complex League this season.

Red Sox promote pitching prospect Blake Wehunt to Triple-A Worcester

The Red Sox have promoted pitching prospect Blake Wehunt from Double-A Portland to Triple-A Worcester, as was first reported by Tommy Cassell of The Worcester Telegram & Gazette.

After missing most of April with a left hamstring strain, Wehunt emerged as one of Portland’s top starters this season. In 13 starts for the Sea Dogs, the 25-year-old right-hander posted a 3.52 ERA with 72 strikeouts to 16 walks over 53 2/3 innings. Opposing hitters batted .235 against him.

Twice recognized as the Eastern League Pitcher of the Week (June 22-28 and June 29-July 5), Wehunt is one of 52 pitchers who have thrown at least 50 innings in the league this year. Among that group, he ranks second in xFIP (3.27), third in strikeout rate (33%), fourth in strikeouts per nine (12.07), seventh in FIP (3.61) and WHIP (1.17), ninth in walks per nine (2.68), 10th in ERA and walk rate (7.3%), 11th in groundball rate (49.2%), and 15th in batting average against, according to FanGraphs.

Standing at 6-foot-7 and 240 pounds, Wehunt throws from a three-quarters arm slot and operates with a diverse pitch mix. In addition to a 93-96 mph power fastball that tops out at 97 mph, the hard-throwing righty features an 89-91 mph cutter, an 83-86 mph sweeper, and an 85-87 mph splitter. He is capable of mixing in a changeup and curveball as well.

Wehunt is currently ranked by Baseball America as Boston’s No. 25 prospect, placing 12th among pitchers in the organization. The Georgia-born chicken farmer was originally selected by the Red Sox in the ninth round (268th overall) of the 2023 draft out of Kennesaw State. He received a $100,000 signing bonus and quickly worked his way up the system in his first full professional season before a lat strain limited him to 63 1/3 innings with Portland last year.

Wehunt, who turns 26 in November, is slated to join Worcester’s starting rotation ahead of its upcoming series against Jacksonville at Polar Park. With his Triple-A debut on the horizon, it is worth noting that Wehunt is reaching the minors’ highest level at a significant time, as he will become eligible for the Rule 5 Draft after the season if he is not added to Boston’s 40-man roster by this winter’s protection deadline.

Taking that into consideration, this promotion should help the Red Sox determine Wehunt’s role in the organization as they continue to evaluate his future.

Red Sox promote power-hitting IF prospect Mason White to Double-A Portland

The Red Sox have promoted power-hitting infield prospect Mason White from High-A Greenville to Double-A Portland, as was first reported by Andrew Parker of SoxProspects.com.

White is currently ranked by both Baseball America and SoxProspects.com as Boston’s No. 27 prospect. The 22-year-old has reached the upper minors in his first full professional season after being selected by the Red Sox in the fourth round (118th overall) of last summer’s draft out of the University of Arizona. He received a $642,200 signing bonus and made his pro debut with Low-A Salem before moving up to Greenville, where he opened the 2026 campaign.

In 68 games for Greenville out of the gate this year, White batted .270/.362/.525 with 14 doubles, three triples, 14 home runs, 42 RBIs, 36 runs scored, 31 walks, and 63 strikeouts over 282 plate appearances. The left-handed hitting slugger slashed .317/.417/.537 in 48 plate appearances against lefties and .261/.350/.522 in 234 plate appearances against righties.

Among 71 qualified South Atlantic League hitters entering play Saturday, White ranks ninth in isolated power (.254), 10th in slugging percentage and OPS (.887), 11th in batting average, 14th in wOBA (.386), 15th in wRC+ (121), 18th in swinging-strike rate (10%), 24th in on-base percentage, and 27th in strikeout rate (22.3%), according to FanGraphs.

Defensively, White primarily split his playing time with Greenville between second base and shortstop. In 35 starts at second, the 5-foot-11, 178-pounder committed two errors in 136 chances across 308 1/3 innings. In 27 starts at short, he committed one error in 87 chances across 237 1/3 innings. He also made five starts at DH.

White, who turns 23 in September, is the third member of Boston’s 2025 draft class to make the jump to Portland this season, joining third-rounder Anthony Eyanson and 13th-rounder Jack Winnay. Though there will be questions about how he adjusts to tougher, higher-quality pitching at Double-A, his promotion nonetheless helps the Sea Dogs address the void left by fellow infielder Marvin Alcantara, who was placed on the 7-day injured list on Friday.

Red Sox promote pitching prospect Hayden Mullins to Triple-A Worcester

The Red Sox have promoted pitching prospect Hayden Mullins from Double-A Portland to Triple-A Worcester, as was first reported by Tommy Cassell of The Worcester Telegram & Gazette.

Mullins was slated to start Worcester’s series opener against Rochester at Polar Park on Tuesday, but it was postponed due to inclement weather. The 25-year-old left-hander will now presumably get the starting nod and make his Triple-A debut in either Game 1 or 2 of Wednesday’s scheduled doubleheader.

Mullins is reaching the minors’ highest level for the first time following an up-and-down start to his season with Portland. In 12 outings (11 starts) for the Sea Dogs out of the gate, the southpaw posted a 5.85 ERA with 73 strikeouts to 31 walks over 47 2/3 innings in which Eastern League opponents batted .215 against him. That includes a .182 mark against left-handed hitters and a .236 mark against right-handed hitters.

Among 49 pitchers who entered play Tuesday having thrown at least 45 innings in the Eastern League this year, Mullins ranked first in strikeouts per nine (13.78), second in strikeout rate (34.8%), fourth in swinging-strike rate (15.7%), sixth in batting average against, 16th in FIP (4.16), and 17th in xFIP (4.13). On the flip side, he also ranked 28th in WHIP (1.43), 40th in ERA, and 46th in walks per nine (5.85) and walk rate (14.8%), according to FanGraphs.

Mullins is currently ranked by Baseball America as Boston’s No. 21 prospect, placing 12th among the system’s pitchers. The Tennessee native was originally selected by the Red Sox in the 12th round (369th overall) of the 2022 draft out of Auburn. He signed for just $97,500 but did not make his professional debut until the following August, as he was recovering from the Tommy John surgery that cut his junior season short.

After splitting the remainder of the 2023 campaign between the Florida Complex League and Low-A Salem, Mullins spent all of 2024 and the first part of 2025 with High-A Greenville before arriving at Portland last April. He fared well in his first stint with the Sea Dogs despite missing time in May due to shoulder fatigue, forging a 2.44 ERA across 18 starts (84 2/3 innings) en route to being recognized as the team’s Pitcher of the Year.

Even in light of that production, Mullins was somewhat surprisingly left off the Red Sox’ 40-man roster last November, leaving him available to other clubs in December’s Rule 5 Draft. He did not get picked, however, and remains in the organization without occupying a 40-man spot.

Listed at 6-foot and 194 pounds, Mullins possesses plus extension and features a 93-94 mph fastball that is capable of reaching 96 mph. The lefty also mixes in an 81-85 mph slider, a 77-80 mph sweeper, an 81-83 mph changeup, and a recently-implemented cutter. His secondaries are considered by Baseball America to be “inconsistent,” even though they “can all miss bats.”

Mullins, who turns 26 in September, can once again become Rule 5-eligible this winter if he is not added to Boston’s 40-man roster by the November protection deadline. Barring a trade or another move between now and then, he can further strengthen his case for a roster spot with a strong showing down the stretch at Worcester.

Red Sox to promote catching prospect Franklin Primera to Low-A Salem

The Red Sox are promoting teenage catching prospect Franklin Primera from the Florida Complex League to Low-A Salem, as was first reported by Chris Hatfield of SoxProspects.com.

Primera, who turned 19 earlier this month, lit up the Florida Complex League to begin his first season stateside. The right-handed hitter batted .427/.549/.718 with six doubles, eight home runs, 29 RBIs, 30 runs scored, four stolen bases, 22 walks, and 13 strikeouts in 32 games (134 plate appearances) for the rookie-level FCL Red Sox. He slashed .250/.478/.250 in 24 plate appearances against lefties and .460/.564/.805 in 110 plate appearances against righties.

Among 73 qualified hitters in the FCL entering play this week, Primera leads in batting average, on-base percentage, slugging percentage, OPS (1.267), wOBA (.571), and wRC+ (202). He also ranks second in strikeout rate (9.7%), sixth in isolated power (.291), seventh in swinging-strike rate (7.6%), and 24th in walk rate (16.4%), according to FanGraphs.

Defensively, Primera saw most of his playing time in the FCL at catcher. Primarily splitting reps with Jorge Rodriguez, the 6-foot, 230-pound backstop allowed five passed balls and threw out 17 of 101 would-be base stealers in 23 starts behind the plate. He also made eight starts at first base, marking his first exposure there as a professional, and one start at DH.

A native of Venezuela, Primera originally signed with the Red Sox for just $10,000 as an unheralded international free agent in September 2024. He made his professional debut in the Dominican Summer League the following June, emerging as a 2025 DSL All-Star and All-Star Game Co-MVP after hitting a crucial home run for his first (unofficial) round-tripper as a pro.

Thanks to his hot start out of the gate in 2026, Primera is now ranked by Baseball America as Boston’s top catching prospect and No. 19 overall prospect. Evaluators have been impressed by his approach at the plate, his ability to impact the baseball, and his defensive capabilities.

As he prepares for his first taste of full-season ball, Primera is slated to join a Salem catching group that currently includes the likes of Kleyver Salazar, Andonys Guzman, and Andruw Musett. The RidgeYaks are on the road for the next two weeks and open a six-game series against the Augusta GreenJackets on Tuesday.

Red Sox promote Newton native, power-hitting prospect Jack Winnay to Double-A Portland

The Red Sox have promoted corner infield prospect Jack Winnay from High-A Greenville to Double-A Portland, as was first reported by Andrew Parker of SoxProspects.com.

Winnay, who turned 23 earlier this month, is in his first full professional season. The Newton, Mass. native (and Belmont Hill alumnus) was selected by the Red Sox in the 13th round (388th overall) of the 2025 draft out of Wake Forest. He received an at-slot $150,000 signing bonus and debuted at Low-A Salem last August, batting .321/.393/.434 with one home run and 11 RBIs in a limited 15-game sample.

After integrating himself with the Red Sox player development program over the winter, Winnay entered his first spring training with little fanfare and broke camp with Greenville as an unranked prospect. The right-handed hitter struggled out of the gate, slashing just .184/.382/.250 with one home run and nine RBIs in his first 23 games (102 plate appearances) for the Drive through May 3. From there, however, he began to turn a corner offensively — particularly in the power department — and hit .304/.470/.598 with 10 home runs and 23 RBIs across his next 33 games (149 plate appearances) before being promoted late Sunday.

Overall, Winnay batted a respectable .255/.434/.457 with five doubles, 11 home runs, 31 RBIs, 43 runs scored, 53 walks, and 51 strikeouts in 56 games (251 plate appearances) for Greenville to begin the 2026 season. He posted a .364/.475/.788 clip in 40 plate appearances against lefties and a .232/.427/.387 clip in 211 plate appearances against righties.

Among the 80 qualified hitters in the hitter-friendly South Atlantic League, Winnay ranks second in walk rate (21.1%), fourth in on-base percentage, sixth in wOBA (.413), ninth in wRC+ (136), 12th in swinging-strike rate (8.9%), 14th in OPS (.891), 22nd in strikeout rate (20.3%), 27th in isolated power (.202), 28th in slugging percentage, and 35th in batting average, according to FanGraphs.

Defensively, Winnay primarily split his playing time with Greenville between the two corner infield positions. The 6-foot-3, 220-pounder made a team-leading 40 starts at third base, committing 12 errors in 94 chances, and 14 error-free starts at first base. He also made one start at DH and has prior experience in the outfield.

Thanks to his recent hot stretch at the plate, Winnay is now regarded as Boston’s No. 40 prospect by SoxProspects.com. He is not yet ranked by Baseball America or MLB Pipeline, but that may not be too far behind, given the amount of attention he has received as of late.

Winnay joins third-round right-hander Anthony Eyanson as the second member of the Red Sox’ 2025 draft class to reach the upper minors this season. As was the case for Eyanson — who has forged a 1.46 ERA through his first six Double-A starts (24 2/3 innings) — the jump to Portland represents a new challenge for Winnay in the form of more advanced competition.

The Sea Dogs hit the road and open a six-game series against the Hartford Yard Goats on Tuesday night.

Red Sox to promote prospects Enddy Azocar, Luke Heyman to High-A Greenville

The Red Sox are promoting prospects Enddy Azocar and Luke Heyman from Low-A Salem to High-A Greenville, as was first reported by Hunter Noll of Beyond the Monster.

Azocar, a 19-year-old outfielder, and Heyman, a 22-year-old catcher, are currently ranked by Baseball America as Boston’s Nos. 10 and 25 prospects, respectively. The pair were among Salem’s top offensive performers to start the season (they are tied for the team lead in home runs) and are being rewarded with a new challenge in a promotion to Greenville.

Azocar played in 39 of Salem’s first 45 games and was swinging a hot bat as of late. The right-handed hitter batted .295/.344/.530 with 15 doubles, three triples, six home runs, 26 RBIs, 31 runs scored, seven stolen bases, 12 walks, and 40 strikeouts over 180 plate appearances. That includes a .372/.426/.767 line against lefties and a .268/.316/.447 line against righties.

Heyman, another right-handed hitter, played in 36 games for Salem to mark his professional debut. He slashed .218/.383/.420 with six doubles, six home runs, 21 RBIs, 19 runs scored, 31 walks, and 36 strikeouts across 154 plate appearances. His platoon splits are similar to Azocar’s, as he batted .276/.462/.448 off of southpaws compared to .200/.357/.411 off of right-handers.

Defensively, both Azocar and Heyman were used exclusively at one position when not serving as DH for Salem. Azocar, who is up to 6-foot-2 and 195 pounds, made 30 of his 39 starts and logged 260 error-free innings in center field, recording one assist. Heyman, who is listed at 6-foot-4 and 220 pounds, made 22 of his 36 starts and logged 190 1/3 innings behind the plate, allowing four passed balls and throwing out 15 of 53 would-be base stealers.

Azocar, a native of Venezuela, originally signed with the Red Sox for $40,000 as an international free agent in January 2024. His stock first started to rise last year following a strong spring and impressive showing in the Florida Complex League. With five-tool potential and encouraging underlying data, he has emerged as one of the organization’s top teenage talents. He does not turn 20 until next February.

Heyman, meanwhile, was acquired from the Mariners for reliever Alex Hoppe in November. Selected in the 14th round (422nd overall) of last summer’s draft out of Florida, he received an above-slot $230,000 signing bonus. Because he was rehabbing from a fractured forearm that cut his junior season short, however, Heyman did not appear in a game for a Seattle affiliate before being dealt to Boston. He turns 23 in July.

Azocar and Heyman are now slated to join an exciting position player group in Greenville that includes other ranked prospects like Justin Gonzales, Henry Godbout, Yoeilin Cespedes, Gerardo Rodriguez, and Mason White. The Drive open a six-game series at home against Asheville on Tuesday night.

With Azocar and Heyman on the move, the Red Sox are also promoting 18-year-old infielder Louis Andujar from the Florida Complex League to Salem, according to Ari Alexander of 7News Boston WHDH.

Red Sox promote pitching prospect Dylan Brown to High-A Greenville

The Red Sox have promoted pitching prospect Dylan Brown from Low-A Salem to High-A Greenville, as was first reported by Chris Hatfield of SoxProspects.com.

Brown, who turns 22 next month, was Boston’s eighth-round pick (238th overall) in last summer’s draft out of Old Dominion. The left-hander received an at-slot $229,000 signing bonus but did not make his professional debut until April 2. He has since gotten his pro career off to a promising start.

In five starts for Salem, Brown forged a 2.31 ERA with 32 strikeouts to 13 walks over 23 1/3 innings in which he held Carolina League opponents to just a .181/.299/.241 clip. That includes a .167/.274/.185 line against right-handed hitters and a .207/.343/.345 line against left-handed hitters.

Among 23 qualified Carolina League pitchers entering play Tuesday, Brown ranked third in groundball rate (59.2%), fourth in FIP (2.83), strikeouts per nine (12.34) and strikeout rate (33%), sixth in batting average against and ERA, and seventh in swinging-strike rate (15.4 percent) and xFIP (3.80), per FanGraphs.

A Pennsylvania native, Brown is currently ranked by SoxProspects.com as Boston’s No. 60 prospect but figures to move up in the site’s next update. The 6-foot-5, 230-pound southpaw has a deceptive delivery and features a four-pitch mix that consists of a lower-90s fastball that has reached 95 mph, an upper-80s cutter, a lower-80s slider, and a lower-80s changeup.

“So far, he’s been able to consistently keep hitters off balance and locate all his pitches around the strike zone,” Baseball America’s Ian Cundall (formerly SoxProspects.com’s scouting director) wrote of Brown last month. “If that continues, he could become another intriguing pitching prospect to watch in a system full of them.”

With fast-rising righty Anthony Eyanson moving up to Double-A Portland, Brown will be tasked with facing more advanced competition at High-A. He joins a Greenville starting rotation that includes fellow 2025 draftees Kyson Witherspoon and Marcus Phillips. The Drive open a six-game series on the road against the Greensboro Grasshoppers on Tuesday night.

Red Sox to promote top pitching prospect Anthony Eyanson to Double-A Portland

After a handful of starts for High-A Greenville, Anthony Eyanson is ready to move up to the next level. The Red Sox are promoting the talented pitching prospect to Double-A Portland, according to Chase Ford of MiLB Central.

Eyanson is just days removed from making his fifth (and perhaps final) start for Greenville at home this past Friday. Going up against Hub City at Fluor Field, the 21-year-old right-hander allowed one hit and three walks (the first three of his professional career) while striking out seven of the 15 batters he faced over 3 2/3 scoreless innings. He threw 67 pitches (37 strikes) and generated 11 whiffs.

In five starts for Greenville altogether, Eyanson posted a minuscule 0.44 ERA with 34 strikeouts to three walks over 20 1/3 innings. Opponents in the South Atlantic League batted just .104/.155/.149 against him. That includes a .114/.139/.114 line from right-handed hitters and a .094/.171/.188 line from left-handed hitters.

Among 26 South Atlantic League pitchers who had thrown at least 20 innings this year entering play Sunday, Eyanson led in batting average against, ERA, FIP (1.46), strikeouts per nine (15.05), strikeout rate (47.9%), swinging-strike rate (22%), WHIP (0.49), and xFIP (1.31). He also ranked third in groundball rate (59.4%) and walks per nine (1.33), and fourth in walk rate (4.2%), per FanGraphs.

Eyanson was selected by the Red Sox with the 87th overall pick in last summer’s draft out of Louisiana State (by way of UC San Diego). The California native received an over-slot $1.75 million signing bonus and stood out in his first spring training with the club by displaying significant velocity gains. He touched triple digits in the Spring Breakout game on March 20 before breaking camp with Greenville in early April.

Since making his pro debut one month ago, Eyanson — throwing from a high release point — has hovered between 95-97 mph and topped out at 98-99 mph with his fastball. The 6-foot-2, 208-pound hurler also incorporates an 86-88 mph slider, a cut-splitter, and a 79-80 mph high-spin curveball into his arsenal, which he described to The Boston Globe’s Alex Speier as “very vertical.”

“I think north-south, and just keeping stuff over the plate and in the zone,” Eyanson told Speier last Thursday. “I’m trying to throw everything in the zone and just let the pitch move on its own, and let the hitter give himself his own problems.”

Eyanson, who does not turn 22 until October, entered 2026 as Baseball America’s No. 13 Red Sox prospect but now has legitimate top 100 buzz surrounding him. He is the first member of Boston’s 2025 draft class to reach Double-A and, like left-hander Payton Tolle a year ago, could be on the fast track to the major leagues.

First, though, comes a new challenge: facing more advanced competition in the upper minors with Portland. The Sea Dogs open a six-game series against New Hampshire at Hadlock Field on Tuesday.

Red Sox promote pitching prospect Brandon Neely to High-A Greenville

The Red Sox have promoted pitching prospect Brandon Neely from Low-A Salem to High-A Greenville, according to the club’s MiLB.com transactions log.

Neely, 22, was originally taken by the Red Sox in the third round (86th overall) of the 2024 draft out of Florida. The former Gator and First Team All-SEC selection received an under-slot $700,000 signing bonus, but spent the entirety of his first full professional season on the injured list due to forearm stiffness.

Instead of pitching for a Red Sox minor league affiliate, Neely spent most of his 2025 rehabbing in Fort Myers. The right-hander was, however, cleared in September to take part in the Arizona Fall League. He then made five appearances (one start) for the Salt River Rafters, allowing 16 runs (14 earned) on 16 hits, eight walks, and 11 strikeouts over 10 innings.

“It was nice to be out there competing again,” Neely said of pitching in the Arizona Fall League when speaking with Mac Cerullo of The Boston Herald earlier this spring.

Following a healthy offseason, Neely broke camp with Salem and made his official pro debut on April 8. In two relief outings for the RidgeYaks leading up to Friday’s promotion, the 6-foot-2, 210-pound righty yielded just one earned run on one hit, one walk, and eight strikeouts across 4 2/3 innings. That translates to a 1.93 ERA and a 0.43 WHIP.

Neely, who turns 23 in July, is currently ranked as Boston’s No. 49 prospect by SoxProspects.com, which notes that he “checks a lot of boxes the Red Sox look for,” including “a unique delivery with a low release height” and “a fastball with solid traits and bat-missing ability.” He complements his mid-90s heater, which touches 97 mph, with a slider and changeup.

Given that his first two outings of the season came eight days apart (April 8 and 16), it would not be surprising to see Neely make his High-A debut in Greenville’s game against Asheville on Friday night (April 24). If so, he would work in relief of starter Kyson Witherspoon at some point.

In addition to promoting Neely to Greenville, the Red Sox elevated left-handers Michael Sansone (Double-A Portland to Triple-A Worcester), PJ Labriola (Greenville to Portland), and Jason Gilman (extended spring training to Salem) on Friday. Right-hander Danny Kirwin (right shoulder strain) was also sent on a rehab assignment to Greenville.
