The Nationals reassigned Perez to minor-league camp Tuesday, Andrew Golden of The Washington Post reports.
Perez made 10 relief appearances at the big-league level for Washington in 2022 but did little to distinguish himself, logging a 7.27 ERA and 2.54 WHIP across 8.2 innings. He'll likely need to turn in quality results at Triple-A Rochester over an extended period to begin the 2023 campaign before the Nationals consider giving him another look in the majors.
