Garrett Cooper has proved he can be a pretty good, productive hitter for the Marlins when he’s healthy. He debuted for the Fish in 2018 and owns a 119 wRC+ since then, the second-best mark among all their players with at least 400 plate appearances (behind only J.T. Realmuto).
But Cooper’s lack of availability has been the problem here. He has never come close to playing a full season as a Marlin, including last year when he appeared in only 71 games due to an elbow injury.
Every year, you can identify different Marlins players who are in a “make-or-break” situation for various reasons.
