The 2016 Aces For Humanity campaign was launched by USANA and the WTA at the BNP Paribas Open and continued in Stuttgart at the Porsche Tennis Grand Prix, where every ace hit by a WTA player at Premier-level events translates into a donation to the USANA True Health Foundation, whose mission is to provide the most critical human necessities to those who are suffering or in need around the world. For every ace hit by any player the WTA donates $5, and for every ace hit by a USANA Brand Ambassador, it’s $10.

USANA Brand Ambassadors Eugenie Bouchard, Samantha Stosur, Kristina Mladenovic, Madison Keys, Sloane Stephens, Monica Puig, and Zheng Saisai.
