The Miami Marlins are calling up top infield prospect Deyvison De Los Santos after just one game of the 2026 season, according to Kevin Barral of Fish on First.
It’s an aggressive move for a 22-year-old who’s played exactly one Triple-A game this year. But that one game was pretty impressive – De Los Santos went 2-for-4 with a home run, three RBIs, and a 1.850 OPS.
Miami opened Friday with a 2-1 win over Colorado. Sandy Alcantara looked sharp, Javier Sanoja collected three hits, and Pete Fairbanks notched a save in his Marlins debut. Now they’re ready to shake things up.
The timing makes sense when you consider De Los Santos’s track record. Back in 2024, he absolutely raked between the Diamondbacks system and Miami’s Triple-A affiliate after coming over in the A.J. Puk trade. Forty home runs, .294 average, .914 OPS across 137 games.
That power potential is what caught everyone’s attention.
Last season told a different story, though. De Los Santos struggled to a .240 average and .672 OPS in 110 games. Those numbers raised some red flags about whether he was ready for the next level.
This spring didn’t exactly scream “promote me” either – .286 with a .619 OPS in limited action. But Miami’s front office must’ve seen something they liked in his approach or mechanics.
What makes this move interesting is the Marlins’ willingness to be aggressive with their young talent. They’re not exactly in win-now mode, so there’s room to let prospects develop at the big league level if they show promise.
De Los Santos brings legitimate power upside to an organization that’s been patient with it’s prospect development. The 40-homer season in 2024 wasn’t a fluke – he’s got natural strength and has shown he can make consistent contact when he’s locked in.
The question is whether last year’s struggles were just an adjustment period or something more concerning. Bringing him up this early suggests Miami thinks it was the former.
If the call-up happens, it’ll be fascinating to see how quickly De Los Santos adapts to big league pitching. The Marlins clearly believe the upside is worth finding out sooner rather than later.
