One possible headline to this post could be "Frustrated Tennis Player Smokes Lineswoman With Racket," but that wouldn't be entirely accurate. Darian King did wheel around and chuck his racket after losing a crucial point, and it did hit the nearby lineswoman, but it's pretty obviously accidental.
Regardless of King's intent, he was disqualified from the Charlottesville Challenger tournament for the act. Instead of flat out calling the lineswoman a flopper (the racket bounces into her with practically no force, but she still collapses to the ground as if it he pegged her square in the spine), we're going to chalk it up to her shock and fear at the situation. Because there's no way that actually hurt.
