UFC 170 drew an announced attendance of 10,217 for a live gate of $1.5 million.
Rousey, Stephen Thompson, Rory MacDonald and Demian Maia earned $50,000 UFC 170 fight-night bonuses.
Total fight time for the 11-bout card was 1:52:32.
Betting favorites went 10-1 at the event. Ernest Chavez (7-0 MMA, 1-0 UFC), who defeated Yosdenis Cedeno (9-3 MMA, 0-1 UFC) in the first bout of the night, was the lone underdog to emerge victorious.
Rousey’s three-fight UFC winning streak is tied with Alexis Davis for the longest active streak in the women’s bantamweight division.
Rousey earned the first non-armbar submission victory of her professional career; she stopped McMann with strikes at the 1:06 mark of Round 1 for her first-ever knockout victory.
Rousey’s quick finish was the fastest knockout in UFC women’s bantamweight history and the sixth fastest knockout in UFC title fight history behind Andrei Arlovski (UFC 55), Frank Shamrock (UFC 16), Tito Ortiz (UFC 30) , Vitor Belfort (UFC 46) and Junior dos Santos (UFC on FOX 1).
Rousey’s knockout stemmed from a knee to the body, marking just the second time in UFC history a title fight has ended with a strike to the body (Georges St-Pierre vs. Matt Serra at UFC 83). The knockdown that led to the finish was the first to stem from a standing strike in 22 UFC women’s bantamweight fights.
Rousey’s 66-second victory marked the shortest UFC main event since dos Santos’ 64-second knockout of Cain Velasquez at UFC on FOX 1 in November 2011. It was also the shortest UFC title fight since that same dos Santos vs. Velasquez bout.
Rousey’s four first-round finishes in UFC/Strikeforce women’s bantamweight competition are the most in history. The only fighter to come close to Rousey in the category is Amanda Nunes, who has earned two such finishes.
Rousey’s total cage time after nine professional fights is 24:32, an average of 2:44 per fight.
McMann suffered the first loss of her professional career.
Daniel Cormier (14-0 MMA, 3-0 UFC) was successful in the first light heavyweight bout of his career.
Cormier’s 79-second victory marked his shortest fight since he recorded a 62-second win in an August 2010 Strikeforce bout.
Patrick Cummins (4-1 MMA, 0-1 UFC) suffered the first loss of his career.
Rory MacDonald (16-2 MMA, 7-2 UFC) has earned his past three UFC victories by decision.
Demian Maia (18-6 MMA, 12-6 UFC) is on the first two-fight losing streak of his 24-fight career.
Maia completed just two of 22 takedown attempts in his unanimous-decision loss to MacDonald. Those 22 takedown attempts were the most ever in a single UFC welterweight bout.
Mike Pyle (26-9-1 MMA, 9-4 UFC) has finished his opponent by knockout or submission in 22 of his 26 professional wins. “Quicksand” has earned four of his past five UFC victories by knockout.
Pyle has recorded third-round finishes on three separate occasions under the UFC banner. The only fighter to record more stoppages in the third round is former two-division champion Randy Couture, who accomplished the feat on six separate occasions.
T.J. Waldburger’s (16-9 MMA, 4-4 UFC) knockout loss to Pyle marked the seventh time in nine career losses he has been stopped by strikes. Three of his four defeats under the UFC banner have come by knockout.
Stephen Thompson (9-1 MMA, 4-1 UFC) has earned three of his four UFC victories by knockout. “Wonderboy” has been awarded a fight-night bonus for two of those knockouts.
Robert Whittaker (11-4 MMA, 2-2 UFC) suffered the first knockout loss of his 15-fight career.
Alexis Davis’ (16-5 MMA, 3-0 UFC) three-fight UFC winning streak is tied with Rousey for the longest in the women’s bantamweight division.
Davis has earned all three of her UFC victories by decision.
Jessica Eye (10-2 MMA, 0-1 UFC) suffered the first decision loss of her 13-fight career.
Raphael Assuncao’s (22-4 MMA, 6-1 UFC) six-fight UFC winning streak is the second longest active streak in the bantamweight division behind champion Renan Barao (seven).
Assuncao improved to 6-0 since dropping to the bantamweight division with his decision victory over UFC newcomer Pedro Munhoz (10-1 MMA, 0-1 UFC).
Assuncao’s 100 significant strikes landed against Munhoz were the most of any fighter on the card. His significant strike landed total was the best of his 12-fight UFC/WEC career, nearly doubling his previous high of 57 against Mike Easton at UFC on FOX 5.
Cody Gibson (11-4 MMA, 0-1 UFC) had his career-high six-fight winning streak snapped as he suffered his first defeat since March 2012.
zach-makovsky-ufc-170Zach Makovsky (18-4 MMA, 2-0 UFC) improved to 4-0 since dropping to the flyweight division this past May.
Makovsky has landed 11 takedowns in his two UFC appearances. He scored five takedowns at UFC 170, the most of any fighter on the card.
Josh Sampo (11-3 MMA, 1-1 UFC) suffered his first decision loss since March 11, 2011 – a span of 1,079 days (nearly three years) and 10 fights.
Erik Koch (14-3 MMA, 3-2 UFC) was victorious in his first lightweight bout since 2008 and recorded a first-round knockout win. In the process, he snapped the first two-fight losing streak of his career and also broke a run of 15 consecutive preliminary-card UFC fights to end in a decision.
Rafaello Oliveira (17-8 MMA, 2-6 UFC) fell to 1-4 since making his return to the UFC in May 2011 with his loss to Koch. “Tractor” has been stopped by knockout or submission in all four of those defeats.
Yosdenis Cedeno (9-3 MMA, 0-1 UFC) suffered his first decision loss since Feb. 4, 2010 – a span of 1,479 days (more than four years) and seven fights.
