BREAKING: Mariners Lands Another Major Commitment from ‘Highly Gifted’ Star to Boost Its Offense
he Seattle Mariners completed a trade with the Cincinnati Reds this week. In the deal, the Mariners acquired right-handed reliever Yosver Zulueta in exchange for minor league pitcher Dusty Revis. As part of the transaction, Seattle also designated Samad Taylor for assignment. The move allowed the team to make space for Zulueta on the club’s 40-man roster.
Yosver Zulueta Joins the Seattle Mariners
Zulueta was designated for assignment by the Reds following their acquisition of veteran reliever Pierce Johnson, making him available to Seattle. The 26-year-old has seen limited time at the major league level. He appeared in just 19 games across his last two seasons with Cincinnati.
In that time, Zulueta has posted a 5.32 ERA. However, his results do not fully reflect his true potential. He has struck out 24.8% of opposing hitters while generating a 54% ground-ball rate. Both positive indicators for a power reliever. Control remains Zulueta’s greatest concern, as his 10.9% walk rate sits above league average.
Zulueta becomes the sixth reliever added to the Mariners’ 40-man roster this offseason. He joins José A. Ferrer, Alex Hoppe, Ryan Loutos, Robinson Ortiz, and Cole Wilcox. This addition suggests that Seattle is continuing to prioritize depth while evaluating potential bullpen roles ahead of the season.
Zulueta operates with a four-pitch mix, throwing a sinker, four-seam fastball, slider, and changeup. His sinker and four-seamer both sit in the mid-to-upper 90s, giving him solid velocity, while his slider and changeup typically come in at the mid-to-high 80s.
During the 2025 season, Zulueta appeared in seven games, going 1–0 with a 6.14 ERA over 7 1/3 innings. He walked four hitters and struck out five. Statcast data shows he relied most heavily on his sinker, which he threw 40% of the time, followed by his slider (34.3%), four-seam fastball (17.9%), and changeup (7.9%). His sinker averaged 96.3 mph, while his four-seamer averaged 95.8 mph.
