Last week, the Miami Marlins made their signing of Christopher Morel official. Sources tell our own Isaac Azout that Morel will not be the last bat added this offseason. Whether it’s via free agency or trade, the Marlins will continue shopping for efficient ways to upgrade an offense that ranked tied for 19th in MLB in wRC+ and 27th in home runs.

Below are four names (two trade targets and two free agents) that should be considered by the Marlins front office.

 

1B Triston Casas (Boston Red Sox)

With the Boston Red Sox acquiring Willson Contreras from the St. Louis Cardinals, former top prospect Triston Casas does not have a clear spot in the club’s future plans.

The American Heritage product is only entering his age-26 season, but he has been hampered by injuries—he was limited to playing 63 games in 2024 and 29 games this past season. Even before suffering a left patellar tendon rupture, Casas was on pace for the worst year of his career.

However, Casas had an impressive .250/.357/.473 slash line prior to 2025. Under previous front office leadership, the Marlins were reportedly very interested in his combination of power and plate discipline. 

Maybe Casas’ value is too low for Boston to move him right now. He could still be helpful as depth behind Contreras. Any potential trade sending him to the Marlins would likely involve the Sox getting starting pitching in return.

 

OF Jo Adell (Los Angeles Angels)

On the other hand, another former first-round pick, Jo Adell, is coming off a career year. Splitting his time between center field and right field, Adell slashed .236/.293/.485/.778 with 37 home runs, 98 RBI and a 112 wRC+.

Adell has always struggled to get on base (career .277 OBP) and he shouldn’t see much action in center field moving forward, but his power stands out. He has two more years of club control remaining.

The Angels pitching depth is still shaky and their lineup is too right-handed-heavy. The Marlins are a natural trade partner, though there hasn’t been any indication yet that Adell is on the market.

 

OF Starling Marte (free agent)

Marte was a very popular Marlins player in 2020 and 2021. Back then, he was their everyday center fielder and No. 2 hitter.

A lot has changed. This past season at age 36, the New York Met slashed .270/.335/.410/.745 with nine home runs, 34 RBI and a 112 wRC+. He averaged only 99 games per year in Queens and he’s mainly a designated hitter at this stage of his career. His speed has also been in a steady decline.

Playing in Miami where Marte already resides might bring out the best in him. The Marlins would platoon him so that he faces left-handed pitching as much as possible.

 

UTIL Luis Rengifo (free agent)

Given the Marlins’ desire for defensive versatility, Rengifo seems like a logical fit. Typically a second baseman/third baseman, he can handle shortstop or any of the outfield spots if needed.

Last season, Rengifo slashed .238/.287/.335/.622 with nine home runs, 43 RBI and a 73 wRC+ through 147 games played. Even in a disappointing season, he struck out under 20% of the time. Prior to that, Rengifo was coming off three straight seasons where he posted a wRC+ over 100, including career-highs of a 118 wRC+ and 24 stolen bases in 2024.

It’s rare for 29-year-olds with solid MLB track records to settle for one-year deals. Rengifo’s uncharacteristically bad 2025 has created a nice opportunity for the Marlins if they believe he’ll bounce back.
