Pete Alonso launched his 32nd home run of the year past a swarm of flying seagulls and into the left-field seats in the 16th inning to give the Mets a 2-1 lead. But the Giants responded quickly against Chris Mazza, who fell just short of earning the first win of his career. Brandon Crawford tied the game back up on an RBI double. Then, with the bases loaded and Mets outfielders swarming the left side of the infield, Donovan Solano knocked in go-ahead run on a walk-off single to right field as the Mets lost 3-2 on Thursday night at Oracle Park.
