Spring training always has a way of putting a spotlight on players fighting for their place, especially as the calendar inches closer to Opening Day and roles begin to take shape. The New York Mets are right in that part of camp, where every at-bat and every inning carries a little more weight. That is why Carlos Mendoza’s comments expressing confidence in Mark Vientos stood out, even as the results on the field have not exactly followed.
At the same time, another situation is unfolding that deserves just as much, if not more, attention. While both players are dealing with similar struggles and the same lack of roster flexibility, the impact on this season is not equal. The Mets have options they can turn to in the lineup if needed, but the situation on the pitching side carries far more importance right now.
Mets face more urgency with David Peterson than Mark Vientos despite similar struggles
Carlos Mendoza made his stance on Mark Vientos clear after the game, backing him despite the slow start this spring. That confidence stands out because the production simply has not been there. Vientos is hitting .040/.077/.080 with one RBI in 25 at-bats, a line that jumps off the page for all the wrong reasons. Even so, the manager's message has been a steady support.

On the surface, the situations look similar. Both players are out of options, and both are coming off stretches of underperformance dating back to last season. The difference is how the Mets are positioned to handle it. In the lineup, there are answers. Third base is locked in with Bo Bichette, while Brett Baty and Jorge Polanco have already been getting looks at first. The odd man out there can slide into the designated hitter spot, giving the Mets coverage if Vientos continues to struggle.
On the pitching side, that kind of flexibility does not really exist. Peterson currently sits as the team’s sixth starter, and with Sean Manaea still trying to sort through his own issues, there is a real need for stability early in the season. That puts more immediate pressure on Peterson to perform, not just improve over time.
The concern is that the results have not shown up. In his latest outing, Peterson went four innings, allowing four runs on five hits with two walks and two strikeouts. That pushed his spring ERA to 5.63, continuing a trend that dates back to a rough second half last season. Unlike the lineup, the Mets do not have an easy way to wait this out or send him elsewhere to reset.
That is where the focus starts to feel a bit misplaced. Vientos may be the more talked-about name right now, but the Mets have ways to manage his struggles without it derailing anything. Peterson’s situation is different. If he does not get on track quickly, it affects the team in a way they cannot easily work around.
