The Marlins optioned De Los Santos to Triple-A Jacksonville on Sunday.
The 22-year-old is heading into his second season as a member of the Marlins' 40-man roster but is still waiting to make his MLB debut. Before garnering a look in the big leagues, De Los Santos will need to tap into more power after taking a step backward at Jacksonville during 2025. After posting a .277 ISO between Double-A and Triple-A in 2024, De Los Santos dropped all the way down to .119 over his 440 plate appearances with Jacksonville last season.
