Diving Deep Into Red Sox-Pirates Blockbuster: Breaking Down Johan Oviedo and Two Prospects

[Nick John]

The Boston Red Sox stayed busy prior to the Winter Meetings, making another big trade following the Sonny Gray deal. On Dec. 4, they brought in their second new pitcher as the team shipped fan-favorite prospect Jhostynxon Garcia to the Pittsburgh Pirates as part of a five-player trade that saw the team bring back talented but oft-injured hurler Johan Oviedo as the main acquisition.

The official deal saw Garcia, who was Talk Sox’s number two prospect at the time, and pitcher Jesus Travieso traded for a package of Oviedo and prospects Tyler Samaniego and Adonys Guzman. The main return is clearly Oviedo, who is under team control for two more seasons and won’t turn 28 until March 2. Oviedo made nine starts in 2025 as he returned from Tommy John surgery, going 2-1 with a 3.57 ERA in 40 1/3 innings. The right-hander struck out 42 batters while walking 23.

What makes Oviedo an intriguing rotation option is his frame (6'6") and extension. His fastball was impressive during his short 2025 season thanks to it reaching an average of 95.5 mph paired with nearly six inches of tailing action. In a short sample last season, Oviedo also demonstrated an ability to limit hard contact, as his average exit velocity (87.6 mph), hard-hit percentage (35.3%) and barrel percentage (6.9%) would have ranked in the upper-third of the league had he qualified.

Along with the fastball, Oviedo has four other pitches: a slider, curveball, sinker and changeup. Though relies heavily on his fastball and slider combination, as they made up 69% of his pitches in 2025. His pitch selection gets a bit interesting when broken down against left-handed and right-handed batters, as his slider sees a drop in usage against the former, being used just 26% of the time, while the curve jumps in usage to 22%. That changes with the latter, his slider becoming his most used pitch against right-handed batters at 38% and the curve down to just 10%. Along with that, Oviedo has showcased an ability to generate whiffs, getting batters to swing and miss 30% of the time last season. Batters in general only managed a .181 batting average off of him as well, showcasing the talent the Red Sox are interested in.

Oviedo continues a trend for the Red Sox, who have made it a point to find pitchers with projectable frames and obvious areas of improvement or streamlining. The major issue besides health with Oviedo is his command. Last season, he had a 13.5% walk rate, and his career mark is up to 11%. Oviedo can be wild, throwing more pitches than necessary and walking a lot of batters, but should the Red Sox pitching lab manage to realize all his potential, we could see a breakout season from Oviedo.

Samaniego was a 15th-round draft pick back in 2021 by the Pirates and will turn 27 at the end of January. Since being drafted, he has yet to make it past Double-A, though he missed time in 2024 and only made 13 appearances. This past season saw him appear in 30 games across four levels, most of them coming with Double-A Altoona where he had a 3.08 ERA across 26 1/3 innings. Samaniego is a left-handed reliever who will most likely open the season with Worcester, though will be on the 40-man roster as Pittsburgh added him to it in November to protect him from the Rule 5 Draft.

Samaniego relies mostly on four pitches: a sinker, fastball, changeup and slider. His sinker is his most thrown pitch, averaging around 93.3 mph and being used heavily against left-handed batters at 67% of his pitch usage. Much like Oviedo, Samaniego seems to limit hard contact, his average exit velocity being just 85.7 mph and his hard-hit percentage being just 22.2%. And while he doesn’t strike batters out as much as Oviedo, he still gets his fair share of strikeouts (23.1%) thanks to a 31.8% whiff rate.

Samaniego will serve as a depth reliever this season, though it wouldn’t be surprising to see him get some time in Boston depending on their need for left-handed pitching. He’s got the height of a pitcher the Red Sox are interested in, as he stands 6’4”, and it wouldn’t be surprising if they manage to get the velocity of his fastball up a tick or two.

The final prospect acquired in the deal, Guzman, was drafted in the fifth round of the 2025 draft by Pittsburgh and is another young addition to the organization’s catching corps. Guzman is the latest young catcher (and second from the 2025 draft) to be acquired by Breslow this offseason. Guzman entering the draft was viewed as a glove-first catcher due to a swing that can often times be stiff and too pull-oriented, but he does have good pull-side power and plate discipline. Guzman played for the Arizona Wildcats in college after transferring from Boston College and hit .328/.411/.496 with a .907 OPS in 62 games. He also had 12 doubles, nine home runs and 44 RBIs. Defensively, he threw out 31% of potential base stealers. Baseball America even stated that "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, who bats from the right side, only played in one game after getting drafted, but went 2-for-5 with a home run and two RBIs. More than likely, he’ll open the season with Single-A Salem, but a promotion to Greenville shouldn’t be off the table at some point in 2026.

In Garcia, the Red Sox gave up a potential power threat, but with the outfield currently as crowded as it is and with talks that Kristian Campbell is expected to play in the outfield full time, it seemed like the writing was on the wall for Garcia. The outfielder made his major-league debut with Boston in August this season, going 1-for-7 with a double and five strikeouts. Now with Pittsburgh, he’s likely to be battling for an Opening Day starting position in spring training.

Travieso, on the other hand, is an interesting arm the Red Sox gave up. He won’t be turning 19 until the end of March. Signed out of Venezuela, Travieso made it up to Salem this season after opening the year in the Florida Complex League. With Salem, he would go 2-0 in seven appearances, six starts, and toss 25 2/3 innings. He struck out 38 in that span and walked just 11. Though, with the many young pitchers in the Red Sox system, it was only a matter of time before one was traded.

To make room on the 40-man roster, the team designated pitcher Cooper Criswell for assignment. The 40-man roster is currently full. 

The Red Sox got better with the trade, taking from an area of strength and bringing in a guy with a ton of potential. Whether he reaches that potential is a different question, but the Red Sox hope Oviedo can pitch as his hulking frame suggests. If he can, the rotation may prove to be the team's biggest strength in 2026.
