Mark Vientos hasn’t dazzled in his limited exposure to first base, but there is a measure of confidence within the organization he can handle the position if needed.

The New York Mets may scramble to find an infielder if Pete Alonso leaves. The Mets could look for a third baseman and move Mark Vientos to first base, or they could trade for a new first baseman.

Mets president of baseball operations David Stearns said, "We also feel really good about the young players that are coming through our system that have the ability to play."

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.

Mets owner Steve Cohen was “brutally honest” regarding negotiations with first baseman Pete Alonso’s camp at Amazin’ Day on Saturday. “I don’t like the negotiations,” a visibly angry Cohen said.

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.
