The Red Sox acquired two interesting prospects along with starting pitcher Johan Oviedo in their five-player trade with the Pirates on Thursday.

Boston landed both 22-year-old catcher Adonys Guzman and 26-year-old left-handed pitcher Tyler Samaniego.

Guzman, a Bronx, N.Y. native, played at Boston College in 2023 before transferring to Arizona. He is known for his excellent arm and defensive skills.

Coming out of high school in 2022, Baseball America graded Guzman’s arm 80 (top of the scale) and his fielding 70 (plus plus) on its 20-80 grading scale.

Pittsburgh drafted him in the fifth round (144th overall) out of Arizona in July. His Baseball America draft scouting report noted, “Guzman remains a glove-first catcher whose swing is often a bit stiff and pull-oriented, though he does have solid pullside power and the plate discipline you might expect of a catcher. His arm remains one of the best in class three years later with excellent carry on his throws that should help control the running game. He threw out 31% of basestealers in 2025.”

The right-handed hitter batted .328 with a .411 on-base percentage, .496 slugging percentage, .907 OPS, nine homers and 12 doubles in 62 games (271 plate appearances) for Arizona as a junior in 2025. He added 44 RBIs, 43 runs and 27 walks compared to 32 strikeouts.

The Pirates selected Samaniego to their 40-man roster last month to protect him from being available in next week’s Rule 5 Draft.

Boston opened a spot on its 40-man roster for him by designating righty Cooper Criswell for assignment.

Samaniego was a Pirates’ 15th-round pick in 2021 out of South Alabama. He has a 3.82 ERA in 127 minor league outings (two starts) and has never pitched above Double-A.

The lefty posted a 3.08 ERA, 0.91 WHIP, 30 strikeouts and six walks while holding opponents to a .189 batting average in 20 outings (26 ⅓ innings) for Double-A Altoona in 2025.

Baseball America wrote that he “has a spotty recent health track record but struck out 44 batters over 38.1 innings in 2025 between four levels. He has a deeper arsenal for a lefty reliever, attacking hitters with two mid-90s fastballs, a two-plane mid-80s slider and a mid-to-upper-80s changeup. Samaniego’s entire arsenal is aided by a lower release slot and above-average extension.”

He spent time on the 60-day IL in 2024 with an elbow injury.
