The Marlins have optioned down struggling outfielder Lewis Brinson, as MLB.com’s Joe Frisaro was among those to tweet. He’ll be replaced on the active roster by Garrett Cooper.

It’s quite a disappointing outcome for Brinson as he prepares to celebrate his 25th birthday. The hope was that he’d have translated his obvious abilities into MLB production by this point. At the moment, Brinson has one year and 58 days of MLB service on his odometer, meaning he can only stay in the minors for 39 days if he’s to crack two full years of MLB service by season’s end.

Brinson turned in a disappointing first season in Miami after arriving as a major part of the Christian Yelich swap. Things have gotten even worse in 2019, as Brinson’s already meager power and walk numbers have cratered yet further.

All told, Brinson is sitting on a .190/.240/.321 slash line with a 30.4% strikeout rate and 4.8% walk rate through 543 plate appearances at the game’s highest level. That’s a fair sight shy of what he has produced over a similar stretch at Triple-A: .342/.398/.560 with 18 home runs and 18 steals in 497 plate appearances. And it’s well short of expectations for a player long tabbed as one of the twenty or so best prospects in baseball.

As for the 28-year-old Cooper, he’ll hope to finally get back to full health and stay that way. He was sidelined most recently with a calf strain. The Marlins have hoped for some time to give him an opportunity to prove he’s capable of hitting in the majors, but he has played in only 36 total games at all levels since joining the organization via trade in the 2017-18 offseason. Cooper will likely see time in the corner outfield and at first base.
