The UFC will crown its 10th titleholder on Friday when the first-ever UFC women’s strawweight titleholder will be determined at The Ultimate Fighter 20 Finale at The Pearl at Palms Casino Resort in Las Vegas.

The UFC first announced the 115-pound weight class in December 2013. Since then, 16 fighters have battled on “The Ultimate Fighter 20” for the chance to compete for the inaugural championship.

That 16-woman field eventually narrowed to two as former Invicta FC champion Carla Esparza (9-2 MMA, 0-0 UFC) and Rose Namajunas (2-1 MMA, 0-0 UFC) advanced through the tournament for the chance to compete for the gold.

In 20 domestic seasons of “TUF,” a championship fight has never concluded the season.

Check below for 30 pre-fight facts about the TUF 20 Finale.

Main event

Namajunas, 22, is the youngest of the 22 fighters scheduled to compete on Friday’s card.

Namajunas can become the youngest fighter in UFC history to win a belt. Reigning 205-pound champion Jon Jones holds the current record (23).

Namajunas earned all three of her victories in the “TUF 20” tournament by submission.

Esparza was the reigning Invicta FC strawweight champion prior to vacating the title to join the UFC roster.

Esparza enters the event on a career-high four-fight winning streak. She has not suffered a defeat since June 2011.

Co-main event

Jeremy Stephens (23-10 MMA, 10-9 UFC) is 3-1 since he dropped to the featherweight division in May 2013.

Stephens’ four knockout victories during his UFC lightweight career are the fourth most in divisional history behind Melvin Guillard (seven), B.J. Penn (six) and Yves Edwards (five).

Stephens enjoys an 8:2 knockdown ratio in UFC competition.

Stephens’ head-kick knockout victory against Rony Jason at UFC Fight Night 32 is the only finish of its kind in UFC featherweight history. And, in just 40 seconds, it’s the fifth fastest knockout in UFC/WEC featherweight history.

Charles Oliveira (18-4 MMA, 6-4 UFC) is 4-2 since he dropped to featherweight in January 2012.

Oliveira’s average fight time of 7:02 in UFC featherweight bouts is the shortest in divisional history.

Oliveira has earned all six of his UFC victories by submission. He has used a different technique to finish his opponent in all of those wins (anaconda choke, triangle choke, guillotine choke, calf slicer, rear-naked choke and armbar).

Oliveira is one of two fighters in UFC history to start his career by winning with six different submission techniques. Ken Shamrock (heel hook, rear-naked choke, strikes, guillotine choke, kneebar and a forearm choke) is the other.

Oliveira’s four submission victories in UFC featherweight competition are the most in divisional history.

Oliveira has earned six submission victories under the UFC banner since his debut on Aug. 1, 2010. Only Urijah Faber has registered as many UFC submissions in that time period.

Oliveira averages 2.4 submission attempts per 15 minutes of fighting, the highest rate of any fighter in UFC featherweight history.

Oliveira has earned six tap-outs in 14 submission attempts for a submission accuracy of 42.9 percent, the third highest rate in modern UFC history.

Oliveira is one of two fighters in UFC history with one of the top-five fastest submissions in two different weight classes. He accomplished the feat in lightweight and featherweight competition. Rousimar Palhares is the only other fighter to accomplish the feat.

Oliveira submitted Eric Wisely at UFC on FOX 2 with the only calf-slicer submission finish in UFC history.

Oliveira is one of seven fighters to earn two UFC submission victories in 2014. He submitted Hatsu Hioki at UFC Fight Night 43 in June and also finished Andy Ogle at UFC Fight Night 36 in February. Faber, Gunnar Nelson, Luke Rockhold, Jake Matthews and Colby Covington and Beneil Dariush are the others.

Oliveira has won seven fight-night bonuses since his UFC debut, third most since his UFC debut. Only Donald Cerrone (10) and Joe Lauzon (8) have earned more fight-night bonuses in that span.

Remaining main card

Daron Cruickshank (16-5 MMA, 6-3 UFC) is one of three fighters in UFC history to earn three knockout victories stemming from a kick to the head. Vitor Belfort and Cerrone are the others to accomplish the feat. He earned his against Erik Koch at UFC Fight Night 40, Mike Rio at UFC on FOX 10, and Henry Martinez at UFC on FOX 5.

K.J. Noons (13-7 MMA, 2-1 UFC) is just 3-5 in his past eight UFC/Strikeforce appearances.

Joe Proctor (10-2 MMA, 3-1 UFC) has earned both of his career knockouts under the UFC banner.

Jessica Penne (11-2 MMA, 0-0 UFC) has earned seven of her 11 career victories by submission. All but one of those finishes came by some form of choke.

Preliminary card

Seo Hee Ham (15-5 MMA, 0-0 UFC) makes her debut as the most experienced fighter in the UFC women’s strawweight division.

Ham has earned 13 of her 15 career victories by decision.

Angela Hill (1-0 MMA, 0-0 UFC) has the fewest pro fights of any active member of the UFC roster.

Angela Managa (11-6 MMA, 0-0 UFC) enters the event on a two-fight losing streak. She has not earned a pro victory since August 2011.

Aisling Daly (14-5 MMA, 0-0 UFC) has earned 12 of her 14 career victories by stoppage. She has earned half of those finishes in the first round.

Alex Chambers (4-1 MMA, 0-0 UFC), 36, is the oldest of the 22 fighters scheduled to compete on the card.
