In a corresponding roster move, the Mets have optioned catcher Mike Nickeas to Triple-A.
Johnson has appeared in 11 games for the Mets this season, collecting 10 hits over 32 at-bats. He owns a career OPS of .579.
The 30-year-old has spent a majority of the year with the club’s Triple-A affiliate, where he’s hit at a clip of .207/.253/.335 with seven doubles, four home runs and 15 RBIs.
Nickeas, 29, only mustered a line of .168/.241/.228 with four extra-base hits over 101 at-bats for the Mets this season. He showed small signs of improvement at the plate during limited playing time in the month of June, but only collected one hit over 16 July at-bats.
