Boxingtalk belatedly salutes Argentina's Edith Soledad Matthysse, who etched a second championship reign into her career at the age of 45, three weight classes up from her original championship division. On February 22nd, Matthysse captured the WBA junior welterweight world title with a commanding performance over previously undefeated American contender Samantha Worthington. The bout came to an abrupt conclusion when Worthington’s corner informed the referee that their fighter would not answer the bell for the ninth round at Little Caesars Arena in Detroit. Worthington’s team cited accumulated punishment and their fighter’s inability to respond effectively to the Argentine’s sustained dominance. Matthysse, who has a very ordinary record of 21-16-1, is the older sister of former welterweight champion Lucas Matthysse. She turned pro in 2007 and reigned as the WBA featherweight champion from 2013, adding the WBC title in a unification bout vs. Jelena Mrdjenovich. Matthysse's championship run ended the following year when she lost a rematch to Mrdjenovich.
