We’ve had so many clothing sponsor changes at the start of the 2018 season that it’s hard to even take note and the latest one is the news that Sloane Stephens, who won the 2017 US Open wearing Under Armour, is now officially endorsing NikeCourt.

I am so excited to share with you all that I have officially joined the NikeCourt family!!!
The 24-year-old Sloane will officially launch her cooperation with Nike at the upcoming Sydney International, a Premier-level tournament she’ll play for the first time.
