Gerardo Parra has inspired one of the most fun trends at a ballpark in MLB.
Back on June 19, Parra changed his walk-up music to “Baby Shark,” a hit children’s song about a family of sharks.
“I wanted to put on something different,” Parra told NBC Sports Washington. “My [two-year-old daughter Aaliyah Victoria] loves that song. Before the game, I tried merengue, reggaeton, hip-hop, then I said, ‘You know what, I want to put in Baby Shark.’ I’m happy for that.”

He had success during the first game after making the change, going 2-for-4 with a home run. That led him to continue using the song for his at-bats.
It didn’t take long for the song to catch on among Washington Nationals fans. Not long thereafter, fans at Nationals Park would break out with a shark chomp for Parra’s at-bats. Even Nationals players joined in.

On Friday, the Milwaukee Brewers visited Nationals Park for the first time this season. That exposed the Brewers’ TV crew to Parra’s Baby Shark song when he pinch-hit in the seventh inning, and they loved it:

They noted that Parra is batting .328 since switching to the new song and was batting .209 before it. You can’t deny the Baby Shark effect!
