Khan keeps title with dominant display

Amir Khan made an impressive American debut as he successfully defended his WBA light-welterweight title with an 11th-round stoppage of Paulie Malignaggi at Madison Square Garden.

Olympic silver medallist Khan, 23, was too quick, too strong and too clinical for former IBF champion Malignaggi as he improved his professional record to 23-1 in his first fight in front of a live US television audience.
