Carlos Mendoza’s first look at Bo Bichette playing third a positive sign for remade Mets

Bo Bichette’s transformation into a third baseman is already underway.

The former shortstop, who recently arrived to the Mets on a three-year contract worth $126 million, worked out in front of manager Carlos Mendoza on Monday in Port St. Lucie, Fla., three weeks before position players are due to report to spring training.

The early reviews were positive, Mendoza told Joel Sherman and Jon Heyman on “The Show” podcast.

“He’s an athlete,” Mendoza said. “We’re looking at a guy that has played shortstop pretty much his whole career. And just watching him today, moving around third base, taking ground balls, creating angles and then the throws to first base, I was telling him, ‘It looks like you played there before.’ ”

Bichette, who played in the 2025 World Series with the Blue Jays, isn’t the only Mets player learning a new position: The team also signed Jorge Polanco to a two-year contract worth $40 million to move to first base, a position that became open after Pete Alonso accepted a five-year deal worth $155 million with the Orioles.

Polanco has only one career appearance at first base. Brett Baty (displaced at third with Bichette’s signing) and Mark Vientos also figure into the equation at first base.
