When the phone call came in about a month-and-a-half ago, José Iglesias didn’t quite believe it. Broadway producers were asking the shortstop, a veteran of 13 seasons in the big leagues, to join the cast of the hit musical “Buena Vista Social Club.”“Are you guys calling the right guy?’” Iglesias asked.“Yes, we know who we’re talking to,” went the voice on the other end. “Are you José Iglesias, ‘OMG?’”Iglesias’ talent as a pop musician became clear while he was still a ball player. Just two years ago, his song “OMG,” short for “Oh my God,” became an anthem for his team at the time, the New York Mets. Under his stage name Candelita, Iglesias performed the song at the Mets’ Citi Field after a game in June 2024.Now, starting Aug. 27 — nearly a full year since Iglesias last played in the majors — he’s agreed to join the Tony Award-winning “Buena Vista Social Club” for a six-week run in the role of the narrator at the Gerald Schoenfeld Theatre in New York. He’s set to become the first Latino Major League Baseball player to perform on Broadway, according to the production, which announced his casting Thursday.Exactly how much singing and dancing Iglesias himself will do is still being worked out, he said, but he expects to perform at least one song in the production. The show, which opened last year, tells a story he was familiar with as a child in Cuba, about a legendary group of musicians in Havana.Iglesias called the opportunity to join the cast “breathtaking.”“There’s a lot of history behind that band, a lot of great memories,” Iglesias said. “How it traveled around the world with authentic Cuban music, I grew up listening to it. My dad was a big fan. It’s literally a dream come true to be part of such a great musical.”The Afro-Cuban band that will be playing behind Iglesias received a Grammy award for 2026’s best musical theater album, as well as a special Tony Award in 2025. The production took home four additional Tonys that year as well.Now, of course, comes the hard part: preparing for the biggest stage in musical theater. At first, Iglesias said he was “really, really nervous.”“I lost some sleep, I’m not gonna lie,” Iglesias said. “Just like we’re gonna face an ace and a good pitcher in the playoffs: that type of energy, that type of adrenaline, that’s how it feels. It was tough, it was tough — but in a good way. In a great way.”
