Mariners Sign Brett de Geus To Minor League Deal

By Nick Deeds | December 9, 2023 at 9:26pm CDT

The Mariners have signed right-hander Brett de Geus to a minor league, according to the transactions tracker on his MLB.com profile page. He has since been assigned to Triple-A Tacoma.

de Geus, 26, began his professional career when he was selected by the Dodgers in the 33rd round of the 2017 draft. He made his big league debut with the Rangers during the 2021 season, though his rookie seasons did not go particularly well. In 50 innings of work split between the Rangers and Diamondbacks, de Geus struggled badly with a 7.56 ERA and 5.07 FIP. He struck out just 17.2% of batters faced while walking 10.5%, ratios his standout 52.5% groundball rate was unable to make up for. Those struggles at the big league level led de Geus to spend the 2022 season in the independent Atlantic League, which he remained in for the start of the 2023 season as well.

Just six appearances into his second season of independent ball, however, he jumped ship to sign with the Royals on a minor league contract. de Geus’s first season back in organized ball saw him post mixed results; while he was shelled to the tune of a 11.45 in 11 innings of work at the Triple-A level, he impressed in 35 1/3 Double-A innings with a 2.80 ERA. Looking under the hood of that Double-A performance, de Geus struck out 20.6% of batters faced while generating groundballs at a 56.8% clip.

Clearly, in signing de Geus Seattle is making a bet that his Double-A numbers last season are more indicative of his overall ability than his 11-inning stint at the highest level of the minors last year. Despite his largely middling results, de Geus could prove to be an interesting piece of bullpen depth as the Mariners enter the 2024 campaign thanks to his proclivity for keeping the ball on the ground. It’s a trait the Mariners clearly value in relief arms, as the club’s bullpen posted an impressive 48.2% groundball rate last season, good for the third-best figure in the majors behind only the Yankees and Cardinals.

    “We may not surpass $100m this year(2019 season), but we’ll push the luxury cap limit when it’s time.”

    Maybe they just dont think this year, last year or any other year will be “the time” so if its not “the time” then they dont have to spend, ever.

    Article should say “Mariners continue to add struggling pitching while leaving giant gaping holes in their lineup”.

    I’ll bet he is affordable. That seems to be the most desirable attribute of Mariner off season additions.

    Just when you said, “what can the Mariners do now?” There they go making an impact signing to silence the critics, putting the whole offseason into perspective, and it’s because of a signing like this, the kind that makes everyone forget about that two-way player from Japan! Who you say? I don’t remember because he’s only a DH in the weaker National League!

        Never thought we had chance and actually glad we didn’t. He is great player but wonder long term and that’s lot of money that team can spread over many positions.

    The Mariners are so busy with there pitching acquisitions that they never seemed to get the hitting right. This Brett De Geus can still be a sensation if he goes up against his new team.

    I have a quiz for you, have the M’s ever developed any of there own infielders? How about the outfield? If you said Rodriquez go to the front of the class. Maybe Dipoto needs to develop the left brain or is that the right one, I never get this right.

      They’ve developed infielders for other teams. Ketel Marte is having a good career with the diamondbacks, and now Noelvi Marte is getting off to a good start for the Reds.

      They did draft and keep Kyle Seager, so there’s one.

      Hey, he had a good year a few years ago in the low minors.
      Maybe he can hit and they’re converting him to left field or third base.

      Or maybe you’re right. They want another good draft pick to develop and trade away.

    When he becomes a solid bullpen arm this year Jerry will just say “I did you guys a favor”
