Left handed reliever Dario Alvarez is set to join the Mets in Miami for tomorrow night’s game. Since Alvarez is already on the 40-man roster, and rosters have expanded, no corresponding move is necessary.
Alvarez was called up briefly on August 22nd, but sent back down on August 24th without seeing any in-game action. He was on the Mets briefly last September once rosters expanded. Between AA and AAA this season, he has held left handed batters to a .133 batting average.
Alvarez was not eligible to be called up on September 1st, since an optioned player must spend 10 days in the minor leagues before being recalled (unless he is an injury replacement). For the same reason, the Mets will have to wait to bring back RHP Logan Verrett.
