Twitter was aflame with animosity between New York Mets and Atlanta Braves fans following the first game of Tuesday's doubleheader between the two National League squads. The Mets defeated the Braves 5-4 in a nail-biter that went right down to the final out. New York Mets fans immediately took to Twitter to gloat over fans of the defending World Series champions.For context, these two fanbases don't like each other one bit. Atlanta Braves fans are still riding the high of league-wide victory in 2021, and Mets fans are living in the moment as their squad's 17-8 record places them atop the MLB.New York Mets and Atlanta Braves fans battle over Twitter after Game 1 of the doubleheaderBoth Braves and Mets fans were on their Twitter A-game this afternoon. Here's some of the best reactions.This Mets fan ran straight into the fire with this blunt Tweet. Not only is it a slap in the face to the 11-14 Braves sitting fourth in the NL East, but it's also some professional trolling against their bitter fans.Delusional Mets Fan@MetsDelusional@Braves We own the division13@Braves We own the division"We own the division" - @ Delusional Mets FanIt didn't take long for Braves fans to clap back. One Twitter user brought up some past glory for Braves fans to indulge on. It's true. The Braves are four-time consecutive National League East penant winners.Jeffrey Kent@JeffKentATL@MetsDelusional @Braves Remind me the last time the Mets won a championship?

Could it be true that Braves skipper Brian Snitker doesn't respect the league-leading Mets enough to start his best player? Unlikely. We'd bet that Ronald Acuna Jr. needed a rest.SB@ShaunWasRightThe Braves don’t even respect the Mets enough to use acuna - speaks volumesThe Braves don’t even respect the Mets enough to use acuna - speaks volumes"The Braves don’t even respect the Mets enough to use acuna - speaks volumes" - @ SBSome New York Mets fans stayed away from the negativity and just focused on their team's victory. For this user, it was a big win. It proved that the Mets aren't "the same old" this year. And he called their old bullpen a "dumpster fire."Perry L.

New York Mets and Atlanta Braves fans alike Tweeted their contempt for the umpire's pitch calling in this game. Take a look at this Tweet depicting the game's close and missed pitch calls.

This user named Andrew called the home plate umpire "atrocious" and couldn't wait to see his pitch calling score. They say umpires don't win or lose games, but some of these fans definitely disagreed with that statement.Andrew@andrewbetssCan’t wait to see the @UmpScorecards for the #Mets and #Braves the home plate umpire is atrocious. #MLB1Can’t wait to see the @UmpScorecards for the #Mets and #Braves the home plate umpire is atrocious. #MLB"Can’t wait to see the @UmpScorecards for the #Mets and #Braves the home plate umpire is atrocious. #MLB" - @ AndrewAnd now the New York Mets and Atlanta Braves battle out game two of the doubleheader.
