The Mets aren't done adding to their bullpen.

According to The New York Post's Jon Heyman, the Mets are among the teams showing interest in left-hander Zack Britton.

As Heyman went on to point out, Britton produced an all-time great season for a closer in 2016 for the Baltimore Orioles under manager Buck Showalter. Britton is also close with Mets' new bullpen coach Dom Chiti.
