TAMPA — Mark Vientos, who has only started 12 major league games at first base and 66 in the minors, may see increased playing time at the position this year as Jorge Polanco is expected to spend significant time as a designated hitter. Vientos took the field at first base for the Mets for the first time this spring during Sunday’s game, signaling a potential shift in his defensive role as the team explores new lineup configurations.
Coaching Staff’s Work with Vientos at First Base
Mets coaches, including infield instructor Tim Leiper and bench coach Kai Correa, have been actively working with Vientos to improve his comfort and effectiveness at first base. Vientos reflected on his debut, saying,
“It’s good to get my feet wet in the first game,”
and added,
“Getting everyday reps over there [will] for sure get me a lot more comfortable.”
Evaluating Defensive Fit Between Third Base and First Base
Some scouts believe Vientos’ skill set may be better suited for first base rather than third base, where he has encountered noticeable defensive challenges. A National League scout commented,
“I think sometimes he tries to do too much at third,”
and noted,
“That could be less of an issue at first.”
Mets coach Mendoza also expressed confidence in Vientos’ glove work at first, emphasizing the importance of his ability to cover the entire base. Mendoza said,
“We know he’s got really good hands, but I think his ability to use the whole bag — corner to corner — when he’s going to stretch for throws [is important].”
Ryan Clifford’s Versatility and Progress in the Outfield
Alongside Vientos, Ryan Clifford, who hit 29 homers over 579 plate appearances last season in Double-A Binghamton and Triple-A Syracuse, is working to become a more versatile defender. Last year, Clifford started 66 games at first base, 27 in left field, and 24 in right field.

Making his Grapefruit League debut on Sunday in left field, Clifford is concentrating on improving his lateral quickness and footwork.
“I try to be quick laterally and make sure my feet are moving and I’m putting myself in the right direction, getting to top speed as quick as I can,”
Clifford shared.
Clifford is also aiming to be more aggressive offensively, striving not to miss ideal pitches during his at-bats. Mendoza is optimistic about Clifford’s potential in the outfield, noting,
“We know the power and the ability to control the strike zone [is there]. It just comes down to him making contact on a consistent basis. He did that in Triple-A.”
Cristian Pache’s Return and Recent Performances
Outfielder Cristian Pache, who has not appeared in the majors since 2024 and spent last season with the Arizona Diamondbacks’ Triple-A Reno affiliate, signed a minor league contract with the Mets during the offseason. Pache was in the Mets’ lineup in center field on Sunday’s game and recorded two hits, showing promise as he competes for a spot on the roster.
Pitching Update: Justin Hagenman’s Spring Start
Right-hander Justin Hagenman, a 29-year-old who made nine appearances for the Mets last season including one start, pitched 2 ¹/₃ innings in Sunday’s start against the Yankees. Hagenman allowed one run on two hits and three walks while striking out three batters, demonstrating encouraging form early in spring training.
Implications of Vientos’ First Base Transition for the Mets
Mark Vientos’ adjustment to first base could prove significant for the Mets, potentially offering more flexibility to the team’s lineup, especially with Jorge Polanco’s anticipated time as a designated hitter. If Vientos settles into the role effectively, it could address defensive concerns and add depth to the infield.
Additionally, the continued development of versatile players like Ryan Clifford and the return of experienced outfielders such as Cristian Pache add layers of defensive and offensive options. Pitchers like Justin Hagenman also contribute to building a stronger, adaptive roster as the Mets navigate spring training challenges before the regular season.
