Amanda Nunes has restored order to what had become a volatile Ultimate Fighting Championship division, filling the power vacuum created by Ronda Rousey’s unexpected fall.

Nunes will put her women’s bantamweight title on the line against Valentina Shevchenko in the UFC 215 co-main event on Sept. 9 at Rogers Place in Edmonton, Alberta. It serves as rematch between the world’s top two fighters at 135 pounds, the “Lioness” having outpointed Shevchenko to a unanimous decision in their initial meeting in March 2016. In two appearances since, Nunes has carved up Miesha Tate to capture the undisputed women’s bantamweight crown and then successfully defended it in an equally dominant performance against the aforementioned Rousey. The 29-year-old Brazilian now operates out of the powerhouse American Top Team camp in Coconut Creek, Florida, where she continues to hone her world-class skills.

During her outstanding career, Nunes has amassed her share of intriguing statistical data:

427: Days she will have spent as UFC women’s bantamweight champion by the time she climbs into the cage to face Shevchenko. It ranks as the second-longest reign in the brief history of the division, trailing only Rousey (1,074).

2.64: Strike differential, according to FightMetric figures. Among active UFC fighters, only Joanna Jedrzejczyk (4.44), Cain Velasquez (4.14), Todd Duffee (3.20) and Kamaru Usman (2.66) are ahead of Nunes in the category.

115: Total strikes by which Nunes has outstruck the opposition during her current five-fight winning streak.

3: Former UFC champions she has defeated. Her list of victims includes Rousey, Tate and Germaine de Randamie.

11: First-round finishes on Nunes’ resume. They include 11-, 14-, 47-, 48- and 68-second stoppages.

21: Percentage of career victories Nunes has secured by submission. All three were the result of rear-naked chokes.

1: Takedowns she has surrendered since her September 2014 defeat to Cat Zingano. Only Shevchenko has managed to get her to the ground.

19: Years of age at the time of Nunes’ pro MMA debut. She submitted to an Ana Maria armbar 35 seconds into the first round of their Prime MMA Championship 2 encounter on March 8, 2008. It remains the only submission defeat of Nunes’ career.

194: Significant strikes landed in eight UFC appearances. They account for more than 74 percent of her offensive output.

150,000: Dollars in post-fight bonus money Nunes has earned in the Ultimate Fighting Championship. She banked $50,000 “Performance of the Night” bonuses for her technical knockout on Rousey at UFC 207, her rear-naked choke submission on Tate at UFC 200 and her rear-naked choke submission on 2004 Olympic silver medalist Sara McMann at UFC Fight Night 73.

2: Countries in which Nunes has competed, her 18 professional bouts split between the United States and her native Brazil. Canada will be the third.

3: Times she has fought into the third round. Nunes owns a 1-2 record in those fights, her victory over Shevchenko offset by losses to Zingano and Sarah D’Alelio.
