JUPITER, Fla. – The Miami Marlins’ preparations for the upcoming season have been dealt a significant blow, as the team announced Sunday that All-Star outfielder Kyle Stowers and recent acquisition Esteury Ruiz will both begin the 2026 campaign on the injured list, according to a report from sportsamo.com. The news casts a pall over what was shaping up to be a hopeful Spring Training for a club aiming to build on recent competitive strides.
The most impactful revelation concerns Kyle Stowers, the dynamic outfielder who blossomed into one of the National League’s premier offensive threats last season. Imaging performed Saturday confirmed a Grade 1 right hamstring strain, an unwelcome recurrence of an injury that had already sidelined him earlier in camp. Stowers is expected to be reassessed in three to four weeks, meaning he will miss at least the first few series of the regular season. This is a particularly bitter pill for Stowers and the Marlins, given his previous stint on the IL for the same ailment. After initially straining his right hamstring earlier in spring and being scratched from the February 28 lineup, the organization had exercised extreme caution, implementing a meticulous running progression and ensuring he received live at-bats on back fields to maintain his timing. Friday’s split-squad game against the Houston Astros marked only his third game back, and his premature exit in the bottom of the third, after feeling tightness while rounding third base, signaled an ominous development.
Stowers’ absence leaves a gaping hole in the Marlins’ lineup. The 28-year-old was the subject of offseason extension rumors, a testament to his burgeoning star power. His breakout 2025 campaign saw him clinch the franchise’s first walk-off victory on Opening Day with a clutch single, setting the tone for a season that saw him blast 25 home runs and drive in 73 RBIs in just 117 games. By August, when his season was prematurely ended by a left oblique strain, Stowers had firmly established himself as one of the National League’s most formidable batters. His blend of power, plate discipline, and leadership qualities makes him an indispensable asset, and his presence in the clubhouse is as significant as his production on the field. The Marlins, who went 21-19 without Stowers after his 2025 season-ending injury, will now have to find a way to replicate his offensive output from day one.
Adding to the team’s woes is the injury to Esteury Ruiz, an outfielder acquired from the Dodgers in a December trade. Ruiz, who was battling for a crucial bench spot and bringing much-needed speed and defensive versatility, sustained a high-grade oblique strain during Friday night’s split-squad game in Jupiter. His timetable for return is a more substantial six to eight weeks, further depleting the Marlins’ outfield depth and flexibility as Opening Day looms. Ruiz’s acquisition was seen as a shrewd move to add another dimension to the roster, and his inability to contribute immediately forces the coaching staff to re-evaluate their early-season strategies.
Manager Clayton McCullough addressed the media with a mix of disappointment and resolve. "I think what it means is one, we want to get Kyle healthy," McCullough stated. "We all know Kyle’s a big part not only on the field and offensively what he brings, but then Kyle’s a great teammate and has a lot of great leadership qualities. It’s unfortunate. He’s bummed out, but also now it’s just, ‘Turn the page, Kyle, and let’s get healthy. Let’s get yourself ready for when you do come back.’" McCullough emphasized the team’s belief in their collective talent: "And [I] told him, like, ‘We’ll be OK. We have a lot of good players, and we’re going to be fine.’ I know he’s disappointed the timing of this thing happening here at the end, he was getting back, but he’ll get himself ready, and we’ll welcome him with open arms when he returns." These words, while reassuring, underscore the significant challenge facing the Marlins’ coaching staff and front office.
With Stowers and Ruiz sidelined, the Marlins’ outfield picture becomes significantly clearer, albeit by unfortunate circumstances. The remaining 40-man outfield options with prior Major League experience are now led by Jakob Marsee and Owen Caissie. Marsee, known for his speed and defensive prowess, projects to be the primary center fielder, a critical position requiring exceptional range and instincts. Caissie, with his powerful left-handed bat, is slated for right field, where his arm strength and potential for extra-base hits will be vital. Fellow left-handed slugger Griffin Conine and right-handed hitting Heriberto Hernández are the other natural outfielders on the 40-man roster, likely competing for playing time in left field.
Beyond these dedicated outfielders, the Marlins possess some valuable utility pieces. Gold Glove-winning infielder Javier Sanoja, renowned for his defensive versatility, can competently cover outfield spots in a pinch. Similarly, Christopher Morel, who is expected to primarily handle first base duties, also has experience in the outfield, providing another layer of depth. The team has also been experimenting with Connor Norby in left field during Spring Training, a move aimed at expanding his defensive versatility, and he was back out there Saturday following the injury announcements. This kind of positional flexibility will be crucial as the team navigates the early part of the season without two key contributors.
The depth concerns extend beyond the 40-man roster. As of Sunday, Miami had only 12 healthy position players in big league camp, a stark reminder of the tight margins. Middle infielder Jared Serna and corner infielder Deyvison De Los Santos, both talented prospects yet to make their MLB debuts, were optioned to Triple-A Jacksonville earlier this spring but represent potential call-ups if further injuries strike. Kemp Alderman, the Marlins’ No. 9 prospect and reigning Minor League Player of the Year, has impressed with 29 Grapefruit League plate appearances but is not on the 40-man roster. To add him or an external candidate, the club would likely place right-hander Adam Mazur, who is recovering from elbow surgery, on the 60-day injured list, freeing up a crucial roster spot.
The Marlins’ front office will undoubtedly be scouring the free-agent market and waiver wire for reinforcements. Veteran outfielders like Tommy Pham and Jesse Winker are still available, offering experience and varying skill sets. Pham could provide a right-handed bat with a track record of production and defensive reliability, while Winker offers a left-handed power threat. Daniel Johnson, a non-roster invitee with 152 career MLB plate appearances between 2020-2025, is another internal option if the team needs a quick fill-in. As other teams make final roster cuts leading up to Opening Day, Miami could also claim a player off waivers, a common strategy to bolster depth late in spring.
"We’ll look to see how that final spot now gets filled whether that’s internal or there’s still time leading up to the season, if that’s an external addition," McCullough confirmed, highlighting the ongoing evaluation process. "We’ll have 13 position players on Friday when we get going, and we feel good about what we have. We feel like we have enough players that have the ability to play multiple spots and can move pieces around whether it’s matchups or just how guys are performing, to dictate who gets that playing time."
This unfortunate turn of events marks a concerning pattern for the Marlins, as it’s the second consecutive year key position players have succumbed to injuries during the latter stages of camp. In March 2025, both Connor Norby and outfielder Jesús Sánchez opened the season on the injured list with left oblique strains, mirroring the current situation. Such recurring issues could raise questions about conditioning programs or simply be a cruel twist of fate, but either way, they undeniably disrupt team chemistry and preparation for the rigorous 162-game schedule.
The loss of Stowers and Ruiz presents a significant challenge for the Miami Marlins as they prepare for Opening Day. While the team expresses confidence in its depth and versatility, the absence of an All-Star caliber player and a promising new acquisition will test the resilience and strategic acumen of the coaching staff. The focus now shifts to player development, maximizing the existing roster, and making astute personnel decisions to navigate the early weeks of the season, all while hoping for swift and full recoveries for their sidelined stars. The path to contention just got a little steeper, but the Marlins are determined to climb it.
