Mariners acquire lefty Robinson Ortiz from Dodgers

The Seattle Mariners and Los Angeles Dodgers each announced that Seattle has acquired left-hander Robinson Ortiz in exchange for minor league right-hander Tyler Gough.

Neither player has any big league experience, but the trade is likely more about the Dodgers’ desire to clear a spot on their 40-man roster. Tuesday is the deadline for teams to set their rosters in advance of the Rule 5 Draft, and Friday is the non-tender deadline, making for a very busy upcoming week of roster churning.

Interestingly, it was only 10 days ago that Los Angeles selected Ortiz’s contract to the 40-man roster, but the Dodgers have now changed course and sent Ortiz to Seattle. L.A. now has 38 places filled on its 40-man, while the Mariners have at least 39 spots addressed and potentially a full 40 depending on when Josh Naylor’s new contract is made official.

Ortiz (who turns 26 in January) had spent his entire pro career in the Dodgers organization prior to Sunday’s trade. Between the canceled 2020 minor league season and multiple injury problems, Ortiz pitched only 22 2/3 innings over a five-year span covering the 2020-24 seasons, but the 2025 campaign represented some return to relative normalcy. The southpaw posted a 2.73 ERA and 28.3% strikeout rate over 59 1/3 combined innings at three different minor league levels, with Ortiz making his debuts at both the Double-A and Triple-A levels last year.

A nasty slider/sinker combo has led to a lot of strikeouts for Ortiz, though control has continued to be an issue, as evidenced by his 13.2% walk rate in 2025. Seattle is notably thin in left-handed pitching, as Gabe Speier currently represents the only lefty slated to be part of the Mariners’ bullpen mix next year. Ortiz adds a bit more depth in that department, and there appears to be plenty of upside for Ortiz as a relief weapon if he can cut back on the free passes.

Gough was a ninth-round pick for the Mariners in the 2022 draft, and he posted a 4.66 ERA over 125 2/3 innings at A-level Modesto in 2023-24, starting 32 of his 33 career gmes. A Tommy John surgery in September 2024 has since kept Gough off the mound, though the usual TJ recovery timeline should put the right-hander in line to be ready for a healthy spring training come February.
