Red Sox prospects Sadbiel Delzine, Franklin Primera named FCL Pitcher and Player of the Week

The Red Sox swept the weekly awards in the Florida Complex League on Monday, as prospects Sadbiel Delzine and Franklin Primera were named Pitcher and Player of the Week for June 8-14.

Delzine was dominant in his latest outing for the rookie-level FCL Red Sox last Tuesday. Working in relief of the rehabbing Jeremy Wu-Yelland on the road against the FCL Braves, the 18-year-old right-hander allowed only two hits and no walks (though he did hit two batters) while striking out a career-high eight over 6 1/3 scoreless innings.

Finishing with 75 pitches (54 strikes), Delzine generated 14 whiffs en route to improving to 3-0 on the season as the FCL Red Sox routed the FCL Braves, 13-2, at CoolToday Park in North Port. The young righty averaged 96 mph and reached 97.4 mph with his four-seam fastball, a pitch he threw 24 times. He also mixed in a slider, changeup, sinker, curveball, and cutter, according to Baseball Savant.

Through his first six appearances (three starts) of the season for Boston’s FCL affiliate, Delzine has posted a 1.16 ERA (3.03 FIP) with 27 strikeouts to seven walks over 23 1/3 innings in which he has held opponents to a .114 batting average. That includes a .152 clip for right-handed hitters and a .087 clip for left-handed hitters.

Among the 30 pitchers who entered this week having thrown at least 20 innings in the Florida Complex League, Delzine ranks first in batting average against, ERA, FIP, and WHIP (0.69), sixth in walks per nine innings (2.70), seventh in strikeout rate (30.3%), eighth in walk rate (7.9%), 11th in strikeouts per nine innings (10.41), swinging-strike rate (15.6%), and xFIP (4.21), per FanGraphs.

Delzine is currently ranked by Baseball America as Boston’s No. 11 prospect, placing sixth among pitchers in the organization. The native Venezuelan signed with the Red Sox for $500,000 as an international free agent in January 2025. He made his professional debut in the Dominican Summer League last season, but was limited to just 9 1/3 innings due in part to a flexor issue. When on the mound, though, he flashed intriguing potential and has carried that momentum over into 2026.

At 6-foot-5 and 255 pounds, Delzine possesses an imposing, projectable frame and the ability to already touch triple digits with his fastball. He does not turn 19 until January and could very well be ready for a new challenge in the form of a promotion to Low-A Salem in the near future.

The same can be said for Primera, another Venezuelan-born prospect who has been on an absolute tear at the plate of late. In four games for the FCL Red Sox last week, the right-handed-hitting catcher went 8-for-12 (.667) with two doubles, two home runs, 10 RBIs, seven runs scored, one stolen base, five walks, and one strikeout. He notably homered and drove in a career-high six runs as part of a four-hit effort in a 26-6 drubbing of the FCL Braves at the JetBlue Park complex on Thursday.

Primera, who turns 19 on Tuesday, is enjoying a productive first season in the United States. Entering the week, he is batting .458/.596/.778 with five doubles, six home runs, 22 RBIs, 25 runs scored, four stolen bases, 21 walks, and 10 strikeouts through 24 FCL games (100 plate appearances). He is slashing .214/.476/.214 in 22 plate appearances against lefties and an eye-popping .517/.628/.914 in 78 plate appearances against righties.

Among the 37 hitters who came into the week having made at least 100 trips to the plate in the Florida Complex League, Primera ranks first in batting average, on-base percentage, slugging percentage, OPS (1.374), wOBA (.613), and wRC+ (228), second in isolated power (.319) and strikeout rate (10%), and fourth in swinging-strike rate (7.5%) and walk rate (21%), per FanGraphs.

Defensively, Primera has spent most of his time with the FCL Red Sox behind the plate. While primarily splitting catching duties with Jorge Rodriguez, the 6-foot, 230-pound backstop has made 18 starts at catcher, allowing four passed balls and throwing out 11 of 75 would-be base stealers. He has also made five starts at first base, where he has committed one error in 41 chances, and one start at DH.

Hailing from the Venezuelan city of Coro, Primera signed with the Red Sox for just $10,000 as an international free agent in September 2024. He made his professional debut in the Dominican Summer League last season and worked his way from a bench role to an injury replacement in the DSL All-Star Game, where he was named co-MVP after hitting a crucial home run.

Less than a year after receiving that honor, Primera is now ranked by Baseball America as Boston’s top catching prospect and No. 19 overall prospect in the system. Like Delzine, Primera seemingly has little left to prove in rookie ball and should soon be in line for a promotion to Salem for his first full-season assignment.

How did Red Sox pitching prospect, top international signing Sadbiel Delzine fare in professional debut?

Red Sox pitching prospect Sadbiel Delzine missed most of his first professional season due to injury. When on the mound, though, the young right-hander showed flashes of intriguing potential.

As an amateur coming out of Venezuela, Delzine stood out thanks in part to his physical upside, power, and pitchability. Given those traits, the San Felix native drew a great deal of interest from teams — including the Red Sox — leading up to the start of the 2025 international signing period in January.

After celebrating his 17th birthday on January 9, Delzine officially signed with Boston for $500,000 on January 15. Not only did he receive the highest signing bonus of any Venezuelan pitcher in the 2025 international class, but that $500,000 also represents the most the Red Sox have doled out for an international pitcher since they landed Chih-Jung Liu out of Taiwan for $750,000 in October 2019.

Roughly five months after putting pen to paper, Delzine made his professional debut in the Dominican Summer League on June 3. He made three starts for DSL Red Sox Blue over the course of the next two weeks, posting a 4.82 ERA (2.75 FIP) with nine strikeouts to one walk across 9 1/3 innings in which opposing hitters batted .297 against him.

In the weeks following his June 17 outing against DSL Astros Blue (in which he pitched into the fourth inning for the first time as a pro), it was revealed that Delzine had been dealing with right flexor soreness. That ailment led to him being shut down for the remainder of the regular season, though he did return in time to make one playoff start that saw him allow one earned run on one hit, two walks, and one strikeout in his lone inning of work against DSL Athletics on August 26.

The overall body of work is obviously small, but Delzine was one of 31 Red Sox minor-leaguers to throw at least nine regular-season innings in the Dominican Summer League this year. Among those 31, he notably ranked first in groundball rate (64.3 percent), walk rate (2.6 percent), swinging-strike rate (30.8 percent), FIP, and xFIP (3.26), seventh in strikeout rate (23.1 percent), and 10th in WHIP (1.29), per FanGraphs.

“If he’d qualified, Delzine would be right there with Kendry Chourio and Kevin Defrank in the conversation for the best pitching prospect in the DSL,” Baseball America’s Josh Norris wrote on Tuesday. “Alas, an injury limited him to just 9 1/3 innings in the regular season before he re-emerged during postseason play.”

Already, Delzine is listed at 6-foot-5 and 198 pounds, though he is likely even bigger. The imposing righty primarily operates with an upper-90s mph fastball that has reached 96 mph. He also features a mid-80s gyro slider, a low-80s curveball, a mid-80s changeup, and an upper-80s cutter.

“At his best, Delzine showed a loose arm and a projectable body already capable of generating upper-90s velocity with his fastball,” Norris continued. “He backed it with a nasty curveball in the 79-84 mph range and a slider that came in a few ticks hotter. The heat was there when he returned to the mound, but the command of his pitches and synchronization of his body was a bit off-kilter.”

Delzine is currently regarded by Baseball America as Boston’s No. 25 prospect, which ranks 12th among pitchers in the organization. Barring a trade or other surprise move by the Red Sox this winter, he will likely begin his age-18 season by making his stateside debut in the rookie-level Florida Complex League next summer.
