Injuries to Lindor and Soto were unfortunate, but it is part of the game. It is not as if the Mets are the only team that has suffered injuries to key players. However, when you let a stalwart that seldom missed time (Alonso) walk and bring in 2 players with significant histories of missing time due to injuries (Robert Jr. & Polanco) you should anticipate that your regulars are likely to miss time due to injuries.
I think it is apparent that Stearns gambled that Robert Jr. and Semien could return to previous levels of performance after several years of decline. Both ware gambles that failed to payoff.
Bichette has improved the past 6-7 weeks, but he still is still underperforming his usual offensive production. Defensively, he has adjusted reasonably well to third base. The greatest disappointment to me has been Peralta. He has severely underperformed. I don't blame Stearns for either of their disappointing seasons. Sometimes moves don't work out.
With the repeated emphasis on improving "run prevention", the Mets are significantly worse than last season. The Mets are allowing 4.69 runs/game in 2026 after allowing 4.41 runs/game in 2025. The offensive production has dropped even worse,
What concerns me, is that after a trade deadline in which the majority of moves (G. Soto, Helsley, Rogers, and Mullins) failed to work out. The moves this off season (Robert Jr., Semien, Peralta, Polanco, Williams, Weaver, & Bichette) the majority have once again failed to positively impact the team. I am concerned that the Mets can not weather another season of underperformance by Stearns, if they wish to be relevant in the next year or two.*
* - By my count he was 1 for 4 (Rogers) last trade deadline and 2 for 7 (Weaver & Bichette being generous with that one) that weren't total disappointments. He needs to do better than 2 (or 3) for 11 if the Mets hope to be playoff contenders.
