Boxing: Katsidis proves too strong

Australia's Michael Katsidis produced a devastating third-round stoppage of British challenger Kevin Mitchell yesterday to retain his WBO interim lightweight world title. Katsidis had too much firepower for the previously unbeaten Mitchell.

Elsewhere, Amir Khan, of Britain, retained his WBA super lightweight title when the referee stopped a one-sided bout against New Yorker Paulie Malignaggi in the 11th round at Madison Square Garden.
