12:53pm: The Nationals claimed Coste, reports Brian Costa of the Newark Star-Ledger.
7:53am: The Mets placed catcher Chris Coste on waivers, reports Adam Rubin (via MetsBlog). Coste signed a big league deal worth $650K back in December. Rubin says Coste is likely to accept an assignment to Triple A if he clears waivers.
Coste, 37, hit .224/.301/.317 in 230 plate appearances for the Phillies and Astros last year, catching 352 innings. Coste went 3 for 14 with a walk this spring.
On Saturday, ESPN's Jayson Stark said the Mets were hoping to move an excess catcher like Coste or Omir Santos for Triple A pitching depth. The Mets have Rod Barajas, Henry Blanco, Santos, Josh Thole, and Shawn Riggans on the depth chart.
