The Nationals released Castillo last week, Kyle Glaser of Baseball America reports.
Castillo, who memorably signed a seven-year, $72.5 million contract with the Red Sox in August 2014 before losing his spot on the 40-man roster just under two seasons later, hasn't appeared in the majors since 2016. After spending the 2021 campaign in Japan's Nippon Professional Baseball, Castillo returned to North America this winter, signing with the Nationals on a minor-league deal. Ultimately, the Nationals weren't willing to dedicate a roster spot at Triple-A Rochester to a 34-year-old outfielder, who may have to look outside of affiliated ball if he desires to keep his career going.
