In addition to right-hander Johan Oviedo, the Red Sox acquired pitching prospect Tyler Samaniego and catching prospect Adonys Guzman as part of their five-player trade with the Pirates on Thursday night.
Samaniego, who turns 27 next month, was originally selected by the Pirates in the 15th round (433rd overall) of the 2021 draft out of South Alabama. The left-hander received a $75,000 signing bonus and has since logged a 3.82 ERA with 182 strikeouts to 63 walks in 127 career minor league outings (two starts) totaling 158 innings.
Even though he has yet to pitch above the Double-A level, Samaniego was added to the Pirates’ 40-man roster last month to receive protection from next week’s Rule 5 Draft. The Red Sox opened a spot for Samaniego on their own 40-man roster by designating righty Cooper Criswell for assignment.
After ending 2024 on the 60-day injured list due to an elbow injury that required an internal brace, Samaniego did not make his 2025 season debut until May. He rehabbed with Pittsburgh’s Florida Complex League, Low-A, and High-A affiliates before rejoining Double-A Altoona in late June. From there, he posted a 3.08 ERA with 30 strikeouts to six walks in 20 relief appearances (26 1/3 innings) for the Curve. Opposing Eastern League hitters batted just .189 against him.
Listed at 6-foot-4 and 205 pounds, Samaniego operates with a mid-90s fastball that reached 97 mph in 2025, a low-to-mid-80s slider, and a “seldom-used” upper-80s changeup, according to Baseball America. He should provide the Red Sox with some much-needed left-handed relief depth after Brennan Bernardino (Rockies) and Chris Murphy (White Sox) were traded away last month.
Guzman, meanwhile, celebrated his 22nd birthday on Thursday. The Bronx, N.Y., native originally attended Boston College out of high school in 2023 before transferring to Arizona for his sophomore and junior seasons. He was selected by the Pirates in the fifth round (144th overall) of July’s draft after batting .328/.411/.496 with 12 doubles, nine home runs, 44 RBIs, 43 runs scored, 27 walks, and 32 strikeouts in 62 games (271 plate appearances) for the Wildcats this past spring.
Guzman was ranked by Baseball America as the No. 314 prospect in the 2025 draft class and signed with the Pirates for $496,500. The right-handed hitter made his professional debut in Low-A Bradenton’s penultimate game of the season and stood out by going 2-for-5 with one home run, two RBIs, and two runs scored. He also threw out one would-be base stealer.
Per his pre-draft Baseball America scouting report, Guzman, who is listed at 5-foot-11 and 221 pounds, “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.”
Guzman is the third minor league catcher the Red Sox have acquired in the last three weeks, joining Ronny Hernandez (White Sox) and fellow 2025 draftee Luke Heyman (Mariners). He is a candidate to open the 2026 season at either Low-A Salem or High-A Greenville.
