Cardinals: Looking back at the terrible Marcell Ozuna trade

Average-arm and replaceable outfielder

While the two major pieces in this deal were Alcantara and Gallen, the Cardinals did let go of an average arm that could have been used in their bullpen as well as an outfielder that so far has not found his footing in the majors.

Daniel Castano has started 17 games and appeared in 5 more for the Marlins since 2020, amassing a 2-7 record but with a pretty good ERA sitting at 3.89. No one would argue that Castano is a huge loss, but decent, controllable arms are always needed, and adds to the misfire from the Cardinals.

Magneuris Sierra has provided sparks in small stretches during his major league career, but in 278 career games is just a .228/.273/.546 hitter with plus speed and good defense. He is only 26-years old and now on the Los Angeles Angels, so he could carve out a role in the next few seasons.
