Since 2016, every Major League Baseball team has been required to employ a full-time Spanish-language interpreter. It was a watershed moment. Before that, Latino players arrived in the United States with no guarantee that anyone in the dugout spoke their language. Today, that rule is just the foundation of a deeper shift: MLB admitted it couldn’t keep ignoring its own talent.
The problem nobody wanted to see
For decades, players from the Dominican Republic, Puerto Rico, Venezuela, and Mexico arrived in the majors and figured it out as best they could. Some learned English quickly; others never quite got there. Interpreters existed, but they were a luxury for wealthy teams, not a universal right. A pitcher from the Dominican Republic might sit in the bullpen without understanding the catcher’s signs. An outfielder from Venezuela received instructions from his manager through hand signals.
Baseball is a game built on constant communication: strategy, corrections, trust. Without language, everything gets lost in translation. Latino players reported anxiety, isolation, and preventable mistakes. And the majors were losing valuable intel on their own players.
2016: the year the rules changed
MLB’s decision to mandate full-time Spanish interpreters across all teams wasn’t charity—it was recognizing that more than 25% of major league players were born outside the United States, and a significant share speaks Spanish as their first language. Without that resource, teams were leaving money on the table.
Suddenly, a prospect from Puerto Rico could talk to his coach in his native language. A catcher from Mexico could coordinate with his pitcher without middlemen. Teams began investing in interpreters who didn’t just translate words—they understood Latino baseball culture.
Beyond translation
Modern MLB interpreters aren’t translation machines. They understand cultural context, team dynamics, and the differences in how baseball is communicated in the Dominican game versus the Mexican game. Some are former players. Others grew up in Latino communities in the U.S. and straddle both worlds.
This opened doors for players like Juan Soto from the Dominican Republic, who arrived in the majors as a teenager and developed without a language barrier. Or Salvador Perez from Venezuela, who became one of the voices in the Kansas City Royals‘ dugout precisely because he could communicate without friction.
On-field results
The numbers tell the story. Since 2016, the presence and performance of Latino players in leadership positions (catchers, shortstops, starting pitchers) has grown. It’s not coincidence. When a player understands exactly what the manager wants, he makes fewer mental mistakes. When he can voice his concerns, his confidence soars.
Teams like the Atlanta Braves and Los Angeles Dodgers have invested heavily in infrastructure for Latino players: interpreters, nutritionists familiar with Latin American diets, mentorship programs. Their postseason results reflect it.
The gap remains
The 2016 rule was a start, not the finish line. Some teams still treat interpreters as a cost, not an asset. In the minor leagues, where thousands of Latinos play, coverage is uneven. And in coaching, Latinos remain underrepresented in decision-making roles.
But the direction is clear: MLB understood that Latino baseball isn’t a niche—it’s the future. And that future speaks Spanish.

FAQ
Do all MLB interpreters speak only Spanish?
No. Many speak multiple languages (Portuguese, English, Spanish). Some teams employ interpreters for other languages depending on their roster composition.
When did MLB start hiring interpreters?
Always, but informally. The 2016 rule was the first time every team was required to have at least one full-time interpreter on staff.
Has Latino player performance improved since 2016?
Yes. Fewer mental errors, greater confidence in the dugout, and better cultural integration. OPS and ERA numbers for Latino players have been more consistent since the mandate.
