The Mets captured the 8-2 victory over the Braves, after forcing the championship to an 'if' game by clinching a 13-3 win Saturday night.
"It's incredible," Mets coach Elisha Zayas said.
The Mets started the season at 2-5, but Zayas said he knew his team was better than a 2-5 team.
After Monday's victory, the Mets have won 13 of its last 14 games, including five in a row in the tournament after falling into the losers' bracket in the second round.
Brandon Herzburn started on the mound for the Mets, helping his squad to a 2-1 lead after the first inning.
The Mets scored early, with Dennis Bartee leading off with a walk. He scored when Dennis Morelli reached on an error. They both scored on another error on the same play for a 2-0 lead in the top of the first.
The Braves got on with a triple by Brett Chaney who scored on a wild pitch to trail 2-1.
Herzbrun and Morelli handled the pitching duties for the Mets and kept things tight against the Braves.
"I decided after the game on Saturday if they (the Braves) were having trouble with our same pitchers, I was going to throw them," Zayas said.
He felt that the shortened five-inning game on Saturday really helped out his team, especially on the mound.
The scored held until the top of the fourth when the Mets lit up the Braves for three more runs.
Tyler Starley started things off when he was hit by a pitch. Morelli and Herzbrun both reached on walks to load up the bases for Collin Clarke. Clarke was also hit by a pitch, forcing in Starley. Next, Morelli scored on a wild pitch and Herzbrun scored on a balk, giving the Mets a 5-1 lead.
The squad tacked on another in the next inning, when Brandon Harris reached on a dropped strike three and scored on another wild pitch.
The Braves tried to shorten things up in the bottom of the sixth, getting one run across. Trevor Hustad reached on a fielder's choice and scored on a Mark Nowaczewski double, pulling within four, 6-2.
The Mets offense wasn't quite done yet. Harris reached on a fielder's choice and J.J. Delligatti reached on a single that was misplayed in left field. Bartee doubled with two outs, sending both home before getting thrown out on an attempt at getting an extra base for the 8-2 final.
•In the prep division, the Red Sox got a last-minute victory over the Giants, 5-4. This forces an extra game. They will play today at Golden Eagle Regional Park at 8 p.m.
