What Marlins Might Do if Owen Caissie Is Forced to Injured List

In this story:
If there was a team in baseball that came out surprisingly hot straight out of the gate this season, it was the Miami Marlins. The Marlins were on a blistering pace led by their red-headed rookie, Owen Caissie.
When Caissie was swinging a bat well, this team looked like a playoff team. Now, his struggles directly coincide with their record, which now has them looking up at the .500 mark.
Things might have taken a turn for the worse for both Caissie and the Marlins, as he was scratched from the starting lineup in the ballclub's latest game against the Washington Nationals with discomfort in his left tricep, per MLB.com.

Caissie had easily put himself in very early Rookie of the Year conversations, but has had quite the drop-off, striking out almost half the time in the last month, which doesn't pair well with a .138 batting average.
Maybe a forced reset would be the best thing for the rookie. Per MLB.com, manager Clayton McCullough said Caissie should be good after the day off. Bu this condition is still worth monitoring.
It is always in the best interests of the organization to have a backup plan (or two) in case a starter has to take a stint on the dreaded injured list.
Who the Marlins Will Look to if He Goes to the Injured List

Miami is not an organization that is going to pay anybody a massive contract, meaning they rely on building prospects and letting young players thrive. One outfielder might be ready for his chance to join the team if Caissie gets placed on IL is Kemp Alderman.
Alderman has plenty of experience in Triple-A as he has suited up in the highest level of the minors both last season and this year. In 2026 Alderman is hitting .288 while slugging .456 as he has five homers and 15 RBI in 30+ games.
The Marlins have a handful of other outfielders in the pipeline, but none ready for the call-up as guys like Cam Cannarella who have yet to take a swing in Triple-A.

Like most teams in the majors, the Marlins are flirting with the .500 line, but something has to give. They need a big stretch to roll some momentum in the ballclub's favor.
That means Caissie either needs to get healthy or he needs to jump out of this rut. This is his first major league test, mentally, and he has to take it in stride.
