The Mets today tried another avenue to upgrade their bullpen by signing Al Reyes, who was recently waived by the Tampa Bay Rays, to a minor-league contract, The Post has learned.

Reyes was released by the Rays on Aug. 9 when he refused an assignment to the minor leagues. For Tampa Bay this season, Reyes was 2-2 with a 4.37 ERA, but was on the disabled list twice (in April; in June) with right-shoulder trouble.

In 2007, serving as the Rays’ primary closer, he had 26 saves.
