5 August Ratanachai Sorvoraphin w pts 12 Mauricio Martinez, Patong Beach Arena, Phuket, Thailand - WBO. Referee: Samuel Viruet. Scorecards: 116-112, 116-112, 114-114. In a battle of fellow southpaws the champion was forced to survive a rocky first round when Martinez (118) unleashed a series of heavy lefts, but by the third he was back in the fight with his effective countering paving the way. Although Martinez continued to be dangerous, Sorvoraphin (118) was dictating matters by the ninth despite having had a bad spell in the previous session after a clash of heads left him shaken and disorientated. The remaining four rounds saw Sorvoraphin exercise his better hand speed to pick up points and to slam in solid left hooks to make sure of victory, as Martinez gave it his best shot when firing in hefty lefts and rights whenever in range.
