Anything can happen on the tennis court, as proved by Caroline Wozniacki on Tuesday in Indian Wells.

Despite the tumbling setback and subsequent loss of the point, the No. 16th-ranked Dane prevailed 6-4, 6-4 over Madison Keys. She even finished things off with a backhand down-the-line winner in the corner pocket to secure her quarterfinal berth.

Wozniacki found humor in the unexpected mid-match fall, calling out her exasperated eye roll.
