REPORT: Under Armour Signs Bryce Harper to the Biggest Endorsement Deal in Baseball History

Under Armour has Bryce Harper's endorsement through 2026.

Bryce Harper has signed a massive 10-year extension with Under Armour that will keep him with the company through 2026. The exact dollar amount has not yet been disclosed, but a source told ESPN it's believed to be "the largest endorsement deal in history for a baseball player."

The 23-year-old slugger first signed with Under Armour in April 2011, 10 months after the Washington Nationals made him the first overall pick in the MLB Draft. Five years later, Harper is a three-time All-Star and the reigning National League MVP. After such an incredible start to his professional career, it's not hard to see why UA wanted to lock up Harper for the foreseeable future. This July, the company will release the "Harper One," Harper's first signature baseball cleat.

It's difficult to estimate how much Under Armour shelled out to keep Harper on board. MLB players typically don't make as much endorsement money as NBA, NFL and PGA stars, but Harper could be an exception. He's one of the few athletes who came up surrounded by an enormous amount of hype and who then went on to not just meet but exceed expectations. The only recent comparison I can think of is LeBron James. The King recently signed a lifetime deal with Nike that is rumored to be worth close to $1 billion.

Besides having signed Harper through 2026, Under Armour also has Stephen Curry signed through 2024 and Jordan Spieth through 2025. With additional endorsers like Cam Newton and Lindsey Vonn, Under Armour seems to be in a great position moving forward.
