The New York Mets suffered a devastating 8-5 loss to the Arizona Diamondbacks on Wednesday night, largely due to Edwin Diaz's late-game collapse. Diaz walked two batters and then gave up a go-ahead grand slam to Corbin Carroll in the eighth inning, marking Diaz's second straight poor performance. This loss drops the Mets to four games behind the Atlanta Braves for the final NL wild card spot. Luis Severino struggled early, allowing four runs in 4 2/3 innings and dealing with a foot injury. Despite a comeback that included a game-tying home run by Harrison Bader and a go-ahead sacrifice fly by Pete Alonso, the Mets couldn't maintain their lead. The Diamondbacks, led by Carroll's two homers, continue their strong performance in the NL West race.
