Mets playoff collapse, explained: How New York's miserable second half of season led to postseason miss image

With the baseball season officially over, no team disappointed more than the New York Mets.

The Mets had a loud offseason, signing Juan Soto to a huge, 15-year deal as they looked to build off an NLCS appearance in 2024. After a scorching-hot start to the season, New York struggled in the second half of the season to fall well short of the Philadelphia Phillies in the NL East race.

As a result of their struggles, the Mets found themselves in a race for the final NL Wild Card spot with teams that struggled for the entire season. Once the season ended, the Mets found themselves in a position they never thought would be the case in 2025.

Here's a breakdown of how the season went awry for the Mets.

Are the Mets out of the playoffs?

After Sunday's action, the Mets officially missed the playoffs as the Cincinnati Reds earned the sixth and final Wild Card spot in the National League. New York entered Sunday needing a win against the Miami Marlins and a Reds loss against the Milwaukee Brewers to make the playoffs.

However, New York didn't get its wish and will now have to watch October baseball from home. While the Reds and Mets both finished with the same record, Cincinnati had the head-to-head tiebreaker to advance to the playoffs for the first time since 2020.

How did the Mets miss the playoffs?

The Mets undoing begins with their pitching staff. From the start of the season through the middle of June, New York had the best ERA in baseball and was the only team with a collective ERA under 3.00. However, since June 13th, the Mets' ERA was just barely below 5.00 and was the fifth-worst ERA in the league.

This happened because the Mets dealt with several pitching injuries and regression. Griffin Canning, Tylor Megill and Frankie Montas all suffered season-ending injuries, while ace Kodai Senga had a hamstring injury that derailed his season, as he was not the same when he returned.

As a result, the Mets have relied on rookies Nolan McLean, Brandon Sproat and Jonah Tong to save the rotation, and while McLean has been a revelation, Sproat and Tong have been mixed bags. Combine that with poor defense, and the Mets had trouble keeping runs off the board.

New York tried to add reinforcements at the trade deadline with relievers like Ryan Helsley, Tyler Rogers and Gregory Soto, but they were unable to fix the pitching issues. Even though the Mets' offense was among the best in the league in the second half, it didn't matter.

The Mets final two months were a struggle, as they got swept four times while winning just six series. That includes two separate seven-game losing streaks and three seven-game losing streaks this year, a feat that only one team in MLB history could overcome to make the playoffs.

If you extend the timeline to the middle of June, when the Mets had an MLB-best 45-24 record, New York went 38-55 to close out the season. That is among the worst records in all of baseball during that span.
