Boardroom and Under Armour Spotlight Top-tier MLB Talent in ‘King of Diamonds’ Content Series

The four-part series taps Under Armour’s MLB roster to deliver a bold new take on athlete interviews by pairing unfiltered conversations as players flex their off-field skills.

As the MLB playoff race heats up, Boardroom and Under Armour are teaming up on the new content series King of Diamonds. The four-episode drop spotlights some of the top talent in Major League Baseball, including Under Armour athletes Gunnar Henderson, Bobby Witt Jr., Juan Soto, and Bryce Harper. 

King of Diamonds is part of a broader strategy as Under Armour amplifies its baseball brand. The series captures the spirit of UA’s King of Diamonds collection, which launched at this year’s MLB All-Star Game in Atlanta. The collection embodies the bold performance and personal style of each athlete on its MLB roster, combining UA’s innovative technology with gold details and standout style. 

Under Armour’s Senior Vice President of Brand and Americas Marketing Tyler Rutstein tells Boardroom that the approach reflects a new commitment to the “ecosystem of engagement” that blends premium product with diverse storytelling, connecting fans with their favorite athletes in a whole new way. 

In addition to the star-studded series, UA has also re-introduced its All-America game, which brings together some of the best young players in the nation. To be held at Camden Yards on Sept. 13, the game spotlights rising talent. Both Gunnar Henderson and Bobby Witt Jr reflected on their experiences at the game, which jump-started their time with the Under Armour family. Each player will sport uniforms featuring visual inspiration from the King of Diamonds collection. The game will also feature influencer appearances from the Bat Boys and MD Foodie Boys, blending Gen-Z flair with the legacy brand’s commitment to elite baseball. 

Earlier this year, UA also signed Coach Rac, the biggest name on the viral Savannah Bananas. For Rutstein, the Savannah Bananas encapsulate the intersections of sports, entertainment, and fandom that is central to UA’s refreshed approach to baseball. “Look at the audience that [the Bananas] have created and how much fun and joy they’ve brought to the game and just how they’ve challenged even some of the conventions and rules to make it so fans first. That’s the type of fandom that we need to be building within Under Armour.”

With these moves in concert, Under Armour is excited for its future. “We’re bringing together not just the biggest and best athletes within the space, but also really the biggest and best stories,” Rutstein said. “Through compelling content and marquis moments, we’re giving the opportunity for baseball fans to connect with Under Armour differently, and get to know our athletes in a different way too.”

King of Diamonds drops on the heels of UA’s “We Are Football” campaign, which features All-Pro receiver Justin Jefferson alongside top talent from every corner of the sport. The spot also features Gunna, bridging the worlds of sports and culture.
