Triple-A OF Andrew Brown has been promoted and added to the 25-man roster, while reliever Buddy Carlyle has been designated for assignment.
The transaction returns the Mets to having five men on the bench and seven pitchers in the bullpen, three of which are left-handed relievers.
Carlyle allowed one hit and one walk and struck out three during Wednesday’s loss at Wrigley Field. It was his second appearance since being promoted last weekend.
Brown is hitting .359 with 13 home runs and 31 RBI in 142 at-bats in Triple-A this season.
He started the season with the Mets, but hit just .185 with a home run and five RBI in the 27 at-bats before being demoted in late April.
