American boxer Andy Ruiz landed just enough big punches on Luis Ortiz of Cuba to make up for his mistakes and caution in a narrow victory that kept him on the path to a chance to become the WBC heavyweight champion again. Ruiz knocked down Ortiz three times on the way to a victory by unanimous decision Sunday night at the Crypto.com Arena in Los Angeles. Briton Tyson Fury is the reigning champion. 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. Lightweight Isaac "Pitbull" Cruz then stopped Eduardo Ramirez in the second round with two vicious knockdowns.
