WATCH: Serena, Osaka and Rafa in Nike ad 'Never Too Far Down'

Appearing in a new Nike spot titled "Never Too Far Down," tennis stars Serena Williams, Naomi Osaka, and Rafael Nadal inspire in the trying times of a global health crisis.

Alongside the likes of LeBron James, Tiger Woods, Paul George, and more sportspersons of various sports and skills, the racqueteering trio is in grand company.

As the House of Swoosh would have it, "There's a reason we love comeback stories. ... [W]e see ourselves in them - our resolve, our grit, our hope. Now, more than ever, we need these stories to remind us what we're capable of."

Come for the inspo. Stay for the Serena mini-clip at the one-minute mark.
