Mia St. John defeated Christy Martin in a unanimous 10-round decision for the WBC female super welterweight championship at Table Mountain Casino in Friant, Calif., on Tuesday.
St. John lost to Martin when the two fought a decade ago. After the bout both women, St. John, 45, and Martin, 44, announced they would retire.
"If she wants to retire, I'll retire, too," said St. John, according to the Fresno Bee. "I just wanted to retire with the WBC belt around my waist.
"We started together, we're ending together. We're two legends and we're going out at the same time."
St. John's career record is 47-11-2. Martin, a two-time WBC champion, finished 49-7-3.
