Mendoza cited Jared Young and non-roster invitee Joey Meneses as additional options at first base while the third base mix (if Vientos were to take over first base) could include Baty, Luisangel Acuña (whom the Mets have told to get reps at the position) and Ronny Mauricio.

Mendoza mentioned Jared Young and Joey Meneses — both of whom the Mets signed to minor-league contracts this offseason — as options at first base. Young, 29, is on the 40-man roster but boasts only 62 career MLB at-bats. Meneses, 32, is a .231 hitter in 1,114 MLB at-bats.

Speaking to reporters Saturday at the Mets' Amazin’ Day at Citi Field, Mark Vientos confirmed that he's been "taking reps" at first base and is preparing for a potential position change.
