Myers struck out a batter and was charged with two earned runs on three hits over 2.1 innings of relief Saturday in the Mets' 15-3 loss to the Phillies.
Myers was called up for a start Monday in Cincinnati but recorded just four outs before being chased from the game after allowing seven runs. He'll wind up getting just one turn through the rotation before returning to a long relief role. David Peterson will move into the rotation for Sunday's series finale, with Christian Scott (hip) likely to fill that spot afterward.
