Delray Beach Open: Kyle Edmund through as Adrian Mannarino defaults

Edmund is making his debut at the Delray Beach Open

British number three Kyle Edmund went through at the Delray Beach Open as Adrian Mannarino became the Briton's second opponent in succession to default following an angry outburst.

Edmund, 22, led 6-3 5-0 15-0 when the Frenchman was penalised a game for smashing a ball out of the court.

Mannarino had earlier kicked a chair, and hit a ball towards a ball boy.

Edmund's previous match, against Dennis Shapovalov in the Davis Cup, ended with the Canadian being defaulted.

The 17-year-old angrily smashed a ball which hit umpire Arnaud Gabas, who later required surgery to repair a fractured eye socket.

Edmund, the world number 49, had lost to 60th-ranked Mannarino in straight sets at Wimbledon last year, and the Yorkshireman goes on to face American Bjorn Fratangelo or Yen-Hsun Lu of Taiwan in the second round.

Canada's Milos Raonic, the world number four, is the top seed at Delray Beach and a potential quarter-final opponent for Edmund.

Argentina's Juan Martin del Potro is making his first appearance of 2017 after extending his off-season following victory in the Davis Cup in November.
