September After a dismal August, the Mets began September by taking two out of three games from the
Detroit Tigers. In a September 5 game against the Reds, closer
Edwin Díaz loaded the bases with no one out, but struck out two batters and forced a groundout to hang on to a 5–4 victory. Following that win, the Mets lost eight games in a row. On September 13, the Mets briefly fell out of a playoff spot before the Giants lost hours later. On September 14,

However, the Mets proceeded to lose that series to the Nationals, and the Reds sweep over the Cubs dropped the Mets out of a playoff spot for the first time since April 5. Both teams had 80–76 records, but Cincinnati owned the tiebreaker. On September 23, the Mets went to
Wrigley Field to play the Cubs and had one of their most critical games of the year. While the Mets fell behind 6–1, they eventually won 9–7 and had their first five-run comeback since May 19, 2023. The Reds loss also allowed the Mets to reclaim their Wild Card spot. The Mets took that series, to maintain a one game lead over Cincinnati heading into the final series of the season.
