The Marlins have claimed right-hander Brett de Geus off waivers from the Mariners and optioned him to Triple-A Jacksonville, per announcements from both big league clubs. Seattle had designated him for assignment last week when they claimed righty Jonathan Hernández off waivers from the Rangers. The Fish opened a 40-man roster spot earlier today when infielder/outfielder Nick Gordon was designated for assignment to open an active roster spot for Derek Hill, another waiver claimee.
de Geus, 26, signed a minor league deal with the Mariners in the offseason and was selected to their roster in the second week of April. He spent most of the season on optional assignment, only making four appearances for the big league club.
He also pitched for the Rangers and Diamondbacks in 2021 and the combination of those different MLB stints now gives him 53 1/3 big league innings with a 7.26 ERA. His 17.1% strikeout rate is subpar but his 9.9% walk rate is passable while his 51.4% ground ball rate is strong.
That’s generally been the recipe with de Geus. He has 32 Triple-A appearances this year with a 15% strikeout rate, 7% walk rate and 56.6% ground ball rate. The 6.60 ERA at that level this year isn’t pretty but a .365 batting average on balls in play and 59.4% strand rate have surely helped pushed some extra runs across the plate. He spent most of last year with the Double-A affiliate of the Royals, tossing 35 1/3 innings with a 2.80 ERA, 20.6% strikeout rate, 5.6% walk rate and 56.4% ground ball rate.
The Marlins have undergone a massive roster shakeup in the past two weeks. They traded away A.J. Puk, Jazz Chisholm Jr. Trevor Rogers, Tanner Scott, Bryan Hoeing, Bryan De La Cruz, Huascar Brazobán, Josh Bell and JT Chargois prior to the deadline. They brought back numerous prospects in those deals and also had open roster spots to claim Forrest Wall, David Hensley, Jesús Tinoco, Cristian Pache, John McMillon, Hill and de Geus off waivers.
de Geus will provide the Marlins with some depth in the minors who could be called upon whenever they need a ground ball specialist or just a fresh arm in general. He can still be optioned for the rest of this season and two additional campaigns. He also has just over one year of service time, meaning he could theoretically stick on the roster for a long time if he continues to justify his spot.
