Djokovic disqualified from US Open after striking line judge with ball

Djokovic was becoming frustrated after squandering three set points when Carreno Busta served at 4-5, 0-40, then suffering a fall. Having dropped serve to trail 5-6, he swatted a ball reasonably hard to the back of the court, inadvertently striking a female line judge in her throat. It was a shocking end to the top seed’s hopes of winning an 18th Grand Slam title and moving within two of the men’s record total won by Roger Federer.
