Kyrgios urges fight against cancer with Volleying Challenge

Nick Kyrgios is raising awareness for fighting cancer by “taking cancer to the wall.” The challenge, likened to the very successful Ice Bucket Challenge, is simple enough: hit 30 volleys against a wall.

To take the Volleying Challenge, you can hit any kind of volley with any ball against a wall and then nominate three people. Kyrgios chose Gael Monfils, Andy Murray and Alexander Zverev.

The 21-year-old's very public campaign against cancer is an impressive move in the right direction, especially given the criticism he's received lately.

Despite winning three titles and reaching his career-high ranking, his season was tainted once again with poor behavior. He just finished serving a shortened suspension from the ATP tour after "not giving his best effort" against Mischa Zverev in Shanghai.

The Volleying Challenge was started by Paul Sanderson after his wife Briggs passed away from cancer just days after he finally got her access to immunotherapy. Sanderson began a petition in honor of his wife to call for "the cancer industry, cancer organizations, and governments to reorient the primary direction of research, treatment, and funding to safe, potentially curative immunotherapies in every cancer, and, notably, immunotherapeutic vaccines."
