At Citi Field on Wednesday, the game moved with the uneasy rhythm of a staff trying to hold itself together. luis robert jr. surfaced in that tension when Sean Manaea needed help in center field, and the moment briefly hinted at how narrow the margins were in a 7-2 loss to the Diamondbacks. The Mets are not moving to a six-man rotation, manager Carlos Mendoza said, but the questions around their left-handed pitchers are already starting to feel larger than one day’s score.
Why are the Mets not changing the rotation right now?
For now, Mendoza is staying with the current plan. That decision matters because it frames the Mets’ present problem as one of management rather than panic. David Peterson and Sean Manaea have both become part of the discussion, but the club is not making a structural move yet.
Peterson’s outing captured the concern. He gave up five runs over his first two innings before settling down to throw three scoreless. Manaea then took over in relief, where diminished velocity has pushed him into more of a long-man role. His fastball averaged 89. 3 mph, and while his deception and pitchability helped him navigate the first two innings, the Diamondbacks scored two more runs against him in the eighth.
That sequence explains why the Mets’ lefties are under scrutiny. One has been fighting sequencing and location. The other is dealing with a velocity drop. Together, they have forced Mendoza into what the situation calls “figure it out” mode.
What does luis Robert Jr. have to do with this game?
In a game shaped by innings that spiraled early and stabilized late, defensive support became part of the story. Manaea might have escaped the eighth without damage if he had gotten more help from luis Robert Jr., who came close to making two strong plays in center field. One ball was trapped on a diving attempt with one out. Another was nearly turned into an out on what would have been a sacrifice fly, but instead became a two-run double.
That kind of sequence does not erase the pitching issues, but it does show how thin the line can be between a contained inning and a bigger blow. In a season where every arm matters, those plays can keep a bullpen from being asked to do too much.
Is this a deeper problem or just a rough patch?
The answer, at least for now, appears to be somewhere in between. Peterson said he felt “a little off mechanically” in the first two innings and pointed to usage rather than execution, saying the Mets may have relied too heavily on the sinker and changeup and allowed hitters to sit over the plate. That is a fixable-sounding issue, but it still needs fixing.
Manaea’s case is different. The velocity drop is real, and that makes every inning more delicate. Yet he still has some deception, and he helped spare the bullpen after the previous day had already required high-leverage arms. That matters because the Mets know what can happen when the workload gets too heavy. Last season’s injuries and overuse left their relievers with too much to carry.
The depth beyond Peterson and Manaea also matters. Tobias Myers has been excellent so far and could take a start if needed. Christian Scott remains in the wings after Tommy John surgery, with major-league experience and a spring training that left a strong impression. Jonah Tong is expected to become a factor later this year as well, though he still needs development.
What does the bigger picture look like for the Mets?
The Mets’ pitching has been good enough that it is too early to sound alarms. Going into Wednesday’s matinee, they had the second-best ERA in the league, a reminder that the staff’s overall body of work is still solid even as the left-hand side of the rotation draws concern.
That balance is the story now: not collapse, but uncertainty; not a deadline for action, but a need for answers. Mendoza can wait on a six-man rotation because the club has enough options to buy time. Yet every start from Peterson and Manaea will keep testing that patience, and every clean defensive play will carry added weight.
In that sense, luis Robert Jr. became part of a night that said more than the final score. The plays nearly made, the runs that followed, and the bullpen help preserved all pointed to the same reality: the Mets can survive a rough patch, but only if the small moments stop sliding the other way.
