Gerardo Parra was one of the heart-and-soul members of the Washington Nationals and his walkup song of Baby Shark helped define the culture of the 2019 World Series-winning team.

On Sunday, the Nationals revealed the design of their championship rings. The interior arbor featured a shark holding the Commissioner’s Trophy in honor of Parra. Baby Shark “took over Nationals Park every time Parra stepped to the plate,” the team wrote in a release announcing the rings.

“I’m completely overwhelmed about the honor the Washington Nationals organization gave me in our World Champions ring we earned last season,” Parra wrote on Instagram Tuesday. “I cannot say thanks enough to the organization and, of course, our fans, because you were the ones that made the Baby Shark song our anthem.”

Parra added, “I just feel really blessed and I want to say that I will be forever grateful for being a part of the Washington Nationals history! Good vibes only for all of you! Do do do dooooooooooo.”

Parra’s post was liked by the Nationals and Pinkfong.

The two-time Gold Glove-wining outfielder was a part-time player for the Nationals after the team signed him as a free agent on May 9, 2019. The San Franciso Giants designed Parra for assignment after the then 32-year-old got off to a slow start, batting .198 with one home run and six RBIs in 30 games.

But Parra would revive his career and alter Nationals’ history forever a little more than a month later when he came to the plate on June 19 with the popular children’s song Baby Shark blaring from the loudspeakers. An admittedly bizarre choice, Parra would later tell reporters that it was because of his three children. The song kept popping up on his phone as he shuffled through his phone to find a new walk-up song because the family always played it.

“Like, five times,” Parra said. “I never thought I would pick that song.”

Baby Shark became an instant source of good luck. Parra had two hits and the Nationals swept the doubleheader that day. The victories were first of two in a 15-4 run that got the Nationals over the .500 mark.

During the second half of the season, Parra’s walk-up music became a crowd favorite as the Nats faithful began to sing along and do the Baby Shark chomp whenever Parra came up to bat.

Fans began doing the “shark dance” when Parra was called up to bat in Game 4 of the 2019 National League Championship Series, and then again when Parra was called up to pinch-hit in Games 3, 4, and 5 of the 2019 World Series vs. the Houston Astros.

At a soggy Nats Park, Nationals fans did the Baby Shark chomp during Game 7 as the team clinched their first World Series championship.

Parra would later put a plush shark toy into the Commissioner’s Trophy to celebrate while taking photos in Houston.

He did so again at the Nationals’ championship parade and rally.

After the season concluded, Parra had Baby Shark tattooed on his forearm wearing his signature red Bubly sunglasses.

A Gerardo Parra shark bobblehead and Nats’ shark championship items were created in his honor.

During the offseason, Parra signed a two-year deal with Japan’s Yomiuri Giants, ending his short stint as a National. But due to his walk-up music, Parra will forever be a legend in this town.
