SANTA YNEZ, Calif. – Thirty seconds into the biggest fight of his life, undefeated Chad Dawson sat on the canvas and saw a title shot flash before his eyes. Undeterred, the World Boxing Council (WBC) No. 7 light heavyweight contender got up and dominated champion Eric Harding en route to capturing the North American Boxing Federation (NABF) 175-pound crown with a 12-round unanimous decision Friday on “ShoBox.” In the co-feature from the Chumash Casino Resort in Santa Ynez, Calif., unbeaten Mario Santiago won the USNBC featherweight title by recording a seventh-round TKO over Lenny DeVictoria.
