Andy Murray appears to have signed with Under Armour as his new clothing sponsor.

The world No. 6 was reported not to be renewing his agreement with Adidas, and a recent photo on Twitter shows him wearing the American company's shirt while posing with a fan. He would be Under Armour’s highest-profile tennis player; the company also outfits Sloane Stephens and Robby Ginepri.

The deal has not been officially announced, but is expected to be worth less than his previous contract with adidas, which was for five years and £15 million.

The two-time Grand Slam champion has made plenty of changes this off-season. Murray is no longer working with longtime assistant coach Dani Vallverdu and trainer Jez Green, and is getting engaged to girlfriend Kim Sears.
