With the Mets down 1-0 in the bottom of the ninth inning of Wednesday's game against the Chicago Cubs, Jeff McNeil hit a fly ball to left field, allowing Pete Alonso to tag up and head home for the game-tying run. Alonso slid head-first and while reaching for the plate, his hand popped up as he was getting tagged, and was called out.
The umpire crew reviewed the replay for several minutes before deciding the call on the field was upheld, meaning Alonso was out and the game was over.
