UFC 170 results: Ronda Rousey defeats Sara McMann in questionable stoppage

LAS VEGAS -- Ronda Rousey's armbar streak is over. Her streak of winning all of her fights via finish, however remains intact.

Rousey used a monster knee to the liver to finish Sara McMann and retain her UFC bantamweight title in the main event of UFC 170 on Saturday night at the Mandalay Bay Events Center.

The finish, at 1:06 of the first round, appeared to be the second consecutive quick title fight stoppage by referee Herb Dean, on the heels of his fast stoppage of the Renan Barao-Urijah Faber bout at UFC 169.

The bout was billed as a matchup of Olympic medalists, with Rousey's judo matching up against McMann's wrestling. But the bout, while it lasted, was all standup. Both fighters tagged one another with clean punches before a clinch battle emerged.

Rousey got the better of the that positional war, giving her the space to start the finishing sequence in which she landed the knee and McMann dropped to her hands and knees.

Rousey (8-0) landed a couple punches before Dean stepped in and waved it off. McMann got to her feet soon there after.

While Rousey's postfight interview was once again drowned out in the jeers of the crowd, McMann (7-1), ever the classy individual, refused to pin the blame for the loss on the referee.

"I thought it was a good fight," McMann said. "I got hit, no matter how hard you train, when get your liver stung, you're going to feel it. "I would like to get a rematch. I was trying to get back up, it was my own fault."

Rousey successfully defended her title for the second time in eight weeks, having defeated Miesha Tate in the third round at UFC 168.
