Only days after trading 2017 NL MVP Giancarlo Stanton to the New York Yankees, the Miami Marlins would make yet another significant trade sending outfielder Marcell Ozuna to the St. Louis Cardinals on December 14, 2017.
Similar to Stanton, Ozuna was also coming off a career-year, as the-then 26-year-old posted multiple career-high’s during the 2017 season that included a few notable numbers such as 37 home runs, 124 RBI’s, and a .312/.376/.548 slash line across 159 games.
A two-time All-Star with Miami (2016-17), Ozuna also won a Gold Glove and Silver Slugger in 2017, and despite not playing for the organization since that season, still ranks among the Top 10 in Marlins history in categories such as Singles (447), Extra Base Hits (236), and WAR among Positional Players (13.8).
Having seen time with the Cardinals from 2018-19, Ozuna is currently with the Atlanta Braves. As for the four players the Marlins received from St. Louis for Ozuna, where are they now?
Where are the players the Miami Marlins received in the Marcell Ozuna trade now?
The main return for Miami was Alcantara, a Top 10 prospect in St. Louis’ system at the time who has since gone-on to become the current ace of the Marlins starting rotation. The now 26-year-old has made a total of 78 starts with the Marlins from 2018-21, a span that includes a combined 3.48 ERA and a 2019 All-Star appearance, as well as Alcantara coming off a career-year in 2021 that included a 3.19 ERA with 201 strikeouts across 33 starts.
The second of St. Louis’ Top 10 prospects that the Marlins received was Sierra, who was ranked just behind Alcantara in the Cardinals system. After appearing in a total of 211 games with Miami from 2018-21 that included a combined .230/.277/.273 slash line, Sierra elected free agency at the conclusion of the 2021 season, and recently signed a minor league contract with the Los Angeles Angels.
A prospect ranked among the lower-half of the Cardinals Top 30, Gallen would spend only two seasons in the Marlins organization (2018-19), making his major league debut in 2019 during that span. Traded to the Arizona Diamondbacks at the 2019 trade deadline for Jazz Chisholm, Gallen has spent the past three seasons in the Diamondbacks rotation where the right-hander has posted a combined 3.57 ERA across 43 starts.
The final player the Miami Marlins received was Castano, a former 19th round pick by St. Louis back in 2016 who was coming off an impressive 2017 season in Low-A. Castano has spent every season with the Marlins since, a span that includes a combined 3.78 ERA across 50 IP in the major leagues the last two seasons.
