WATCH: Wawrinka hosts challenge with fans in mall

Stan Wawrinka challenged mall-goers to a tennis-inspired obstacle course in a video for Evian, and the result was a ton of fun.

Contestants were greeted outside by a digital Wawrinka, who instructed them to run into the mall, where they'd then go up an escalator, put on an Evian hoodie, grab a gigantic tennis racquet, go down an escalator and sprint across the mall. For the finale, they got to use the giant racquet to hit balls against a wall in attempts at beating the three-time Slam winner himself.

Two other tennis players to feature in a recent Evian video were Maria Sharapova and Madison Keys, who made a song called "I Wanna #LIVEYOUNG."

Keys will be the defending champion next week at the Silicon Valley Classic, which will be played in San Jose for the first time.

Sharapova withdrew from San Jose, while Wawrinka accepted a wildcard into the Citi Open in Washington, D.C.
