UFC 170 by the numbers

The face of women’s MMA returns for her third title defense when “Rowdy” Ronda Rousey faces Sara McMann on Saturday. McMann won an Olympic silver medal in freestyle wrestling at the 2004 Athens Games, while Rousey won an Olympic bronze medal in judo at the 2008 Beijing Games.

In the co-main event, former two-time Olympic freestyle wrestling team member Daniel Cormier makes his light heavyweight debut against former training partner Patrick Cummins, who will be fighting on short notice after replacing Rashad Evans (Evans suffered a knee injury and was forced to withdraw from the card last week).

Here are the numbers you need to know for the fights:

8: Rousey has recorded eight submission victories in her career, seven of which have come in the opening round. Rousey is the only UFC fighter, male or female, to win every fight with the same finish. With another arm-bar victory, Rousey will tie Jeremy Horn for the most wins by arm-bar submission in UFC history.

2: McMann scored two takedowns in her promotional debut at UFC 159 against Sheila Gaff. In McMann's prior four fights outside the UFC, she averaged 6.5 takedowns per fight, including a career-high nine against Raquel Pa'aluhi.

6: Rousey landed a career-high six takedowns in her UFC 168 fight against rival Miesha Tate. Rousey landed three takedowns in each of the first two rounds, eventually finishing Tate with an arm bar.

3: The Rousey-Tate fight ended in the third round, the first time in Rousey’s eight-fight MMA career that she’s gone past the first round. Tate is also the only woman to escape a Rousey submission attempt (two escapes in UFC 168 fight).

9: Rousey has attempted nine submissions in six UFC/Strikeforce fights. In four of those fights, Rousey has finished her opponent with the first submission attempted.

2: Rousey (8-0, 2-0 UFC) and McMann (7-0, 1-0 UFC) are facing off in the second title fight in UFC history to involve two undefeated fighters. Lyoto Machida (14-0) defeated Rashad Evans (15-0-1) for the UFC light heavyweight title at UFC 98.

2: Both Rousey and McMann have won an Olympic medal. Rousey was a two-time Olympian in judo, winning a bronze medal at the 2008 Olympic Games in Beijing. Rousey was also on the 2004 Olympic team in judo, and McMann was on the '04 team in freestyle wrestling. McMann won a silver medal in the women’s middleweight division.

4: If McMann can win the title, she will join Rousey, Randy Couture and Mark Coleman as former Olympians to win a UFC title. Coleman was a freestyle wrestler on the 1992 Olympic team before winning the first UFC heavyweight title at UFC 12. Couture was a three-time Olympian in Greco-Roman wrestling before winning the UFC heavyweight title on three occasions and the UFC light heavyweight title twice.

3: Cormier is the third Olympian on the UFC 170 card, joining Rousey and McMann. Cormier was a member of the 2004 U.S. Olympic team in his discipline of freestyle wrestling. He finished fourth in Athens and was expected to wrestle on the 2008 Olympic team before being sidelined by injury. Despite the injury, Cormier was still a team captain.

2: Cummins was a two-time All-American wrestler at Penn State, finishing fourth in the 2003 NCAA Championships and second in 2004. Cummins went 38-5 in the heavyweight division in 2003-04, his senior campaign.

3: Cormier notched three takedowns in his last fight against Roy Nelson. In three of Cormier's last four fights, he has at least three takedowns.

92: Cormier holds a plus-92 significant striking advantage over his opponents in the UFC. In two fights -- one against Nelson and one against Frank Mir -- Cormier landed 133 significant strikes to just 41 for his opponents.

4: Cummins is 4-0 in MMA competition, ending each of his fights in the first round. While Cummins has a wrestling background, he has two wins by KO/TKO and two wins by submission.
