(UPDATE) Rigondeaux unanimously outpoints Donaire

NEW YORK (AP) -- Guillermo Rigondeaux retained his WBA super bantamweight championship and added the WBO super bantamweight belt, unanimously outpointing Nonito Donaire on Saturday night at Radio City Music Hall.

Rigondeaux improved to 12-0, receiving winning scores of 114-113, 115-112 and 116-111 in the unification bout. He failed to knock out his opponent for only the fourth time since turning pro, but overcame being knocked down twice in the opening minute of the 10th round in a performance that had some booing the lack of action.

Rigondeaux's speed appeared to be too much for Donaire (31-2), who was trying to defend his WBO super bantamweight belt for the fifth time. Donaire, the Professional Boxing Writers Association fighter of the year for 2012, was handed his first loss in 30 fights since 2001.
