The Mets beat the Diamondbacks 5-4 in walk-off fashion extra innings in the series opener at Citi Field. It was an absolutely wild ride; the Mets were in an early hole as David Peterson walked the opposing pitcher Zac Gallen to load the bases in the second inning and then subsequently hit a batter and walked two batters to force in three runs before he was pulled in favor of Robert Gsellman, who retired the final batter in the inning.
At that point, things were looking grim for the Mets. Gallen was dealing and the bullpen was again forced to do some heavy lifting in relief.
