According to David Lennon of Newsday, the Mets designated Casey Fossum for assignment after Sunday's 8-1 loss to the Nationals. Fossum gave up 4 hits and 1 run and notched 4 strikeouts in 3.3 innings of relief this year for the Mets.
The Mets have called up lefthander Ken Takahashi to take Fossum's place. The 40-year-old Takahashi has a 0.77 ERA in six appearances for Triple-A Buffalo.
