While Under Armour has garnered plenty of exposure from its head-to-toe sponsorship of Masters and U.S. Open winner Jordan Spieth, the company has yet to cash in on Spieth gear itself, which has not yet hit the market.

The company took a step closer to making that a reality, as it has filed for three trademarks for what appears to be the golfer's logo.

The logo features two J's with an S that is contained in the white space in between. The filings say the intent is to use the logo on everything from footwear to golf gloves, headwear, eyewear, jackets and pants.

Under Armour spokesperson Diane Pelkey said the company would have no comment on the filings. Spieth's agent, Jay Danzi, could not be reached for comment.

Spieth, who initially was signed by Under Armour in January 2013 after he announced he would turn pro, had the final two years of his deal ripped up in January to give the company and Spieth another 10 years together through 2025. Although terms were undisclosed, sources say that if Spieth continues his pace on the golf course, he'll be one of the highest-paid players in the game. His payments will rise as he gets royalties from sales of his own gear, which is expected to hit the market next year.

Under Armour previously has produced logos for Golden State Warriors guard Stephen Curry, with his initials "SC" that also spell out his number 30, and Carolina Panthers quarterback Cam Newton, whose initials "CN" include his number 1.

Spieth's contract with Under Armour states that he cannot wear any other logos on his body besides the interlocking UA, but he does have other deals with Titleist (clubs), Rolex (watch) and AT&T, which is on his golf bag.

The 22-year-old Spieth finished tied for fourth at the Open Championship at St. Andrews last month in his bid to win three straight majors. He'll have his final shot this year to win another as the PGA Championship tees off next week at Whistling Straits in Kohler, Wisconsin.
