MLB Twitter roasted the Mets for playing Edwin Diaz’s trumpet entrance while down 4-0 in Sunday’s elimination game against the Padres.

In an apparent attempt to liven the mood at Citi Field, the Mets played Blasterjaxx and Timmy Trumpet’s “Narco” song – Diaz’s iconic entrance music – in the top of the eighth inning as the closer ran out onto the field.

With the Mets down 4-0, many believed it was an awkward time for an impromptu pep rally, which had Padres fans trolling their opponent. The ESPN broadcast showed San Diego supporters clapping and dancing along to the song.

“Oh the Slam Diego kids clapping to Narco as Díaz comes in down 4 in the 8th…is brutal,” one person tweeted.

Meanwhile, the Mr. Met mascot was seen holding a trumpet, trying to pump up the crowd while the song played. The awkward moment had some Mets fans waving rally towels, while others sat silent in their seats.

In a now-viral video promoted by Ben Verlander — the brother of Astros ace Justin Verlander — Trumpet can be seen performing the famous Mets tune. However, it was edited with somber funeral music over the original song.

“Oh no! Who did this?!” Verlander, a Fox Sports analyst, tweeted.

“Need Timmy Trumpet for the Mets’ funeral,” one person tweeted.

Another asked, “Will Timmy Trumpet play at the Mets’ funeral??”

Trumpet’s “Narco” song was a phenomenon for Mets fans throughout the season. In late August, the Australian musician performed the song live at Citi Field. 

Mets superfan Jerry Seinfeld blamed the team’s late-season swoon on Trumpet’s performance. The actor compared it to when the Mets brought out the Baha Men in the 2000 World Series to perform “Who Let the Dogs Out” at Shea Stadium.

“I blame that stupid Trumpet performance,” Seinfeld wrote in the Instagram comments of SNY’s account. “Celebrating in season. We haven’t won anything. Bad mojo.

“Same as when the [Baha] Men showed up to play ‘Who Let [the] Dogs Out’ in 2000 WS. Series ended right there.”

The Diaz trumpets weren’t enough “mojo” to keep the Mets alive in Game 3 of the National League wild-card round matchup.

When Diaz took the mound to his walk-on song, the pitcher allowed two more runs to cross the plate — and the game would eventually end 6-0 Padres.
