Here’s a look at eight of the Mets’ worst losses of the season, which helped doom their playoff chances:

May 19: The Mets are shut out by the woeful Marlins for a second straight day, 3-0, and get swept in three games at Miami. The loss is the Mets’ fifth straight, pushing them five games below .500, fueling speculation manager Mickey Callaway will be fired.

May 29: Joc Pederson and Max Muncy each homer against Edwin Diaz, leading a four-run Dodgers’ outburst in the ninth to sink the Mets, 9-8, in Los Angeles.

June 1: Jacob deGrom is removed with a hip cramp in the seventh inning, and Jeurys Familia implodes behind him in a 6-5, 11-inning loss at Arizona.

June 13: After Pete Alonso lobbies the umpires to continue play in the rain in the ninth inning at Citi Field, the Cardinals tie it and the game is suspended. Diaz surrenders the go-ahead run in the 10th inning the next day in a 5-4 loss.

June 23: Seth Lugo is summoned in the eighth inning behind deGrom at Wrigley Field and allows three runs on three hits and a walk in a 5-3 loss to the Cubs.

July 18: With emotions high after four straight wins, the Mets miss numerous opportunities in a 3-2, 16-inning loss in San Francisco. It’s the first of three extra-innings losses for the Mets in the series.

Aug. 14: Steven Matz is yanked after six innings, and just 79 pitches, in Atlanta, despite allowing only one run. Lugo allows five runs in the seventh in a 6-4 loss.

Sept. 3: In their biggest gut-punch of the season, the Mets take a six-run lead into the ninth inning in Washington, but it’s hardly enough. Kurt Suzuki’s walk-off, three-run homer against Diaz completes the improbable meltdown in an 11-10 stunner.
