Under Armour has signed a 10-year sponsorship extension with one of the PGA Tour’s most promising young stars in Jordan Spieth. Spieth first signed with UA after joining the Tour in '12, and he was the first PGA pro to sign a full head-to-toe UA apparel deal. The deal calls for Spieth to be part of the company's international marketing, digital, print and social media campaigns, and he will be part of the UA golf shoe launch this spring as the brand looks to increase its presence in golf.
