The Mets outrighted Perez to Triple-A Syracuse on Tuesday.
Perez was designated for assignment one day after the Mets' Oct. 5 regular-season finale, but he'll stick in the organization for the time being after going unclaimed off waivers. The 30-year-old backstop saw 45 games at the big-league level between the Mets and Pirates in 2022, slashing .149/.214/.298 across 132 plate appearances.
