Maximo Acosta

Miami Marlins infield prospect Maximo Acosta (oblique) has been diagnosed with a Grade 1 left oblique strain and will miss three to four weeks, according to Christina De Nicola of MLB.com. Acosta is a former international prospect who ranked #25 among Marlins prospects in FanGraphs' mid-2025 farm system report. He ended up making his MLB debut before the end of the season, slashing .204/.295/.389 with three home runs, a 9.8% walk rate, a 27.9% strikeout rate, and 91 wRC+ across 19 games. The results at the plate weren't great by any means, but they also weren't necessarily uncharacteristic for a glove-first rookie who was called up midseason. Of course, any chance that Acosta had of making the 2026 Opening Day roster is now down the drain due to his oblique injury. He'll open the year on the injured list, and it'll be tougher for the Marlins to justify sending him right back to the majors when he's healthy.
