The Mets claimed Ramirez off waivers from the Orioles on Monday, Tim Britton of The Athletic reports.
The Mets booted Ramirez from their 40-man roster and then traded him to the Orioles last month, but he's now back in the organization to give them a fresh relief arm. Ramirez holds an 8.74 ERA over eight relief appearances this season between the Mets and Orioles.
