Ronda Rousey vs Gina Carano fight: Rousey wins with a 17-second submission

Mixed martial arts (MMA) star Ronda Rousey has re-retired after demolishing fellow combat sports trailblazer Gina Carano in their long-awaited non-title comeback bout in Los Angeles, defeating her rival by armbar after just 17 seconds.

After a hype-filled build-up, the bout on Saturday was a jarring anti-climax, with Rousey flooring Carano almost immediately before wrestling her into an armbar to end the fight.

American stars Rousey, 39, and Carano, 44, are widely regarded as two of the most important female fighters in the history of MMA, helping to take the sport into the mainstream during their fighting heydays more than a decade ago.

Carano had parlayed her success into a Hollywood career, appearing in several action movie roles, but had not fought since 2009 before her appearance in Saturday’s featherweight bout.

Rousey, a 2008 Olympics judo bronze medallist who subsequently found huge success in the Ultimate Fighting Championship (UFC), retired from the sport in 2016 after suffering back-to-back defeats against Amanda Nunes and Holly Holm.

The fighters were lured back into the cage for Saturday’s card at the Intuit Dome with the promise of a bumper payday that will reportedly see each fighter earn several million dollars from the streaming giant.

Rousey (13-2-0 MMA) secured her 10th submission win, returning to the cage following an exit from MMA in December 2016.

She insisted afterwards her return to the ring was a one-off and ruled out the possibility of fighting again after paying tribute to Carano.

“Gina is the only person who could have brought me back into MMA – she’s my hero,” Rousey said. “She changed my world, and we changed the world, and I’ll never ever forget that or be able to pay that back enough.
