Under Armour was named the official performance footwear supplier of Major League Baseball, effective for the upcoming 2011 season. Under Armour replaces Reebok.

The multi-year agreement gives Under Armour the worldwide rights to produce and distribute the official “silhouetted batter” MLB logo on its MLB Authentic Collection baseball cleats.

As part of this new licensing agreement, Under Armour will have the rights to include the MLB logo and MLB Club marks on the brand's in-store, digital, and print advertising for baseball footwear and will have a feature attraction at MLB All-Star FanFest beginning this summer in Phoenix and throughout the term of the contract.

“Under Armour brings a unique attitude and energy to everything they do, and we're excited to officially welcome them into the MLB family,” said Howard Smith, Senior Vice President, Licensing, Major League Baseball. “Their commitment to performance is respected throughout the industry, and we have no doubt our players and fans will be excited about their baseball footwear.”

“We are excited to take our efforts in baseball to the next level, as this further demonstrates Under Armour's commitment to aligning elite championship athletes with the most innovative performance footwear in the marketplace,” said Matt Mirchin, Senior Vice President, Sports Marketing, Under Armour. “This relationship provides an opportunity to outfit an increasing number of the game's biggest stars, as well as the ability to showcase the Brand's dedication to the sport of baseball.”

This deal is an expansion of Under Armour's current activation within the sport of baseball. Some of the game's top young talent, including World Series Champion and 2010 National League Rookie of the Year Buster Posey, Jonathon Papelbon, Ryan Zimmerman, Matt Wieters, Jose Reyes, and Nick Markakis, have been wearing the brand's signature performance apparel, footwear, and accessories both on- and off-the-field.

This upcoming season the Brand will unveil the latest in cleated footwear with the UA Heater and UA Natural cleats featuring Rotational TractionTM cleat configuration.
