Now flip it. Flip it good.

Perhaps unlikely pals, Evian co-endorsers Maria Sharapova and Madison Keys teamed up for a new, non-verbal advertising spot that shows off their uncanny (or unreal) racquet-to-basket technique and shines a light on recycling for the benefit of the planet.

In another tweet in her thread, Keys noted that she was glad to help the US Open retain its "zero landfill" status, as an eco-friendly venue during the season's major finale (and always).

Sharapova continues her own media-saturating status with not just this water-brand clip but a new guest appearance on ABC network's Shark Tank program.

From sponsorships to sharking the business proposals of others, this pair knows how to stay busy.
