LOS ANGELES (AP) — Andy Ruiz landed just enough big punches on Luis Ortiz to make up for his mistakes and caution in a narrow victory that kept him on the path to a chance to become the heavyweight champion again. Ruiz knocked down Ortiz three times on the way to a victory by unanimous decision Sunday night. Former three-division world champion Abner Mares also fought to a majority draw with Miguel Flores in Mares' return from a four-year ring absence on the pay-per-view undercard.
