Junior flyweight contender José Antonio Aguirre (35-10, 21KOs), 35-years-old, has announced his retirement from boxing. Aguirre made a decision to leave the sport after failing to win the WBC championship from Gilberto Keb on Saturday in Yucatan, Mexico. Aguirre was stopped in nine rounds. He's won only two of his last ten bouts since 2005. During the last few years, Aguirre has been plagued by shoulder problems and they continue to bother him. For many years he was one of the best boxers at 105-pounds as the WBC minimumweight champion. He was never able to adapt once moving up in weight to 108-pounds.
