The Mets designated Diekman for assignment Monday.
Diekman has often been used in high-leverage situations by the Mets this season, even picking up a save less than a week ago. However, he's allowed 10 runs over his last 7.1 innings and has issued 24 walks across 32 frames overall. The Mets could find another team willing to take on Diekman via trade, but they would likely need to eat some of what remains of his $4 million salary in order to facilitate a deal. Diekman's contract also contains a $4 million option for 2025 that vests if he makes 58 appearances this season. He's already made 43 appearances in 2024, which may further deter teams from dealing for the 37-year-old southpaw.
