As Javier Assad took the mound Monday night, a Mexican song known as a corrido — a ballad — blared over the Wrigley Field speakers.

It wasn’t any ordinary song, though.

The tune, written and performed by Banda Corona Del Rey from Mazatlán, Sinaloa in Mexico, is dubbed “Javier Assad” and named after the Cubs’ starter.

Like many other corridos, the song tells the story of a person. Corridos have a long history in Mexican regional music, beginning with the Mexican War of Independence in 1810. The genre has become more popular in recent times. In their song, Banda Corona Del Rey tells the story of Assad in a genre special to him.

“I never thought I’d have my own corrido,” Assad said. “But I was glad they made it and when I heard it, the moments that have passed — it’s really beautiful to listen to it and have all my family in it.”

The lyrics tell of Assad’s rise from Tijuana and up to the major leagues where he has become one of the better pitchers in the league and representing Mexico in the World Baseball Classic. There’s an anecdote about his uncle José Juan who taught him how to play baseball and how the song will one day play at historic Wrigley Field. The ending of the song features the band playing the melody of “Go Cubs Go” as the song fades out.

The origins of the song are quite simple. A few months ago, the group had a mutual connection with Assad and reached out and asked him if he was OK if they wrote a song about him.

Assad agreed and spoke with the band multiple times so they could learn his story and write the lyrics. The band mentions his parents, his cousins who he was close with and his wife, Melissa.

“Everyone is happy,” Assad said. “My wife, my parents, my uncles, my cousins, they’re all happy with everything in the song.”

The group released the song after his start on May 31, so he had to wait a couple weeks before he could finally use the song as a walkout tune since his next two starts were on the road.

When he took the field on Monday, Assad admitted that he heard the song playing as he began his warmup.

“You hear it a little bit, for sure, but then you start concentrating and don’t pay attention to it,” Assad said.

That’s fine for him, though. The song is in constant rotation.

“Well, I listen to it every day,” Assad said with a laugh.

When you have your own song, who can blame you?
