Women’s Strawweight

1. Jessica Aguilar (19-4)

The World Series of Fighting strawweight champion is not the only notable woman in the division outside the UFC, but her position is the most unique. Aguilar, who has not tasted defeat in more than four years, last defended her WSOF strap in November by winning a five-round unanimous decision over tough Brazilian Kalindra Faria and has been vocal about her desire to fight actively against the best women in the world. “Jag” might be the most accomplished woman in the division, but in 2015, the UFC, not the WSOF, is the destination for the top 115-pounders in the world.

2. Carla Esparza (10-2)

In 2010, a 22-year-old Esparza was fast-tracked for success at 115 pounds. Four years later, she validated her hype and promise, dominating Rose Namajunas en route to a third-round submission in the final of “The Ultimate Fighter” Season 20 to become the first-ever UFC women's strawweight champion. However, “Cookie Monster” will have little time to enjoy the thrill of being the inaugural 115-pound champion, as her first defense wilk come against sharp-striking Polish contender Joanna Jedrzejczyk on March 14.

3. Joanna Jedrzejczyk (8-0)

Few women if any had as impressive a 2014 campaign as Jedrzejczyk. The Arrachion MMA Olsztyn fighter earned dominant, eye-opening wins over Karla Benitez, Rosi Sexton and Juliana de Lima Carneiro to earn a crack against highly regarded, unbeaten Brazilian Claudia Gadelha. At UFC on Fox 13 in Phoenix, Jedrzejczyk went well beyond giving Gadelha “a fight,” dropping her late in the first round and winning a contentious split decision that will earn the Polish fighter a crack at new champion Carla Esparza at UFC 185.

4. Claudia Gadelha (12-1)

The 26-year-old Gadelha missed out on “The Ultimate Fighter” Season 20, as she felt she could not make the 115-pound limit several times in a few short weeks. However, many still pegged the Brazilian dynamo as the best strawweight in the world, given the benefit of a full training camp. That idea met stern opposition at UFC on Fox 13 in Phoenix, where Gadelha was upended in a razor-thin split decision loss to unbeaten Polish prospect Joanna Jedrzejczyk. “Claudinha” will attempt to get back on track against Aisling Daly on April 11 in Poland.

5. Karolina Kowalkiewicz (7-0)

Kowalkiewicz encountered her stiffest challenge to date when she went up against Brazilian striker Kalindra Faria at KSW 30, but the Pole emerged with her perfect record intact. Following a submission scare in round one, Kowalkiewicz won the final two frames with short, accurate punches and counterstriking to claim a split decision. The Gracie Barra Lodz product is expected to return to Invicta Fighting Championships, where she sits poised as the top contender to champion Katja Kankaanpaa’s crown.

6. Joanne Calderwood (9-0)

Calderwood was submitted by Rose Namajunas in the semifinals of “The Ultimate Fighter 20,” but the loss has done little to dampen the enthusiasm around the 27-year-old Scottish striking savant. “Bad Mofo Jojo” ably strutted her stuff in her official Octagon debut, dominating rugged Deep Jewels atomweight champion Seo Hee Ham with her standup and showing off the fighting style that will make her a quick favorite in the UFC’s embryonic 115-pound class. Calderwood is set to welcome Ukranian armbar specialist Maryna Moroz to the organization on April 11 in Poland.

7. Katja Kankaanpaa (10-1-1)

One of the unsung stalwarts in the 115-pound division, Kankaanpaa proved her elite status at Invicta Fighting Championships 8 in September with her thrilling fifth-round comeback against Stephanie Eggink, earning the promotion’s vacant title with a brabo choke. Given the working relationship between Invicta and the UFC, it is not hard to imagine the Finnish grinder finding her way to the Octagon in the near future.

8. Tecia Torres (5-0)

Following her stint on “The Ultimate Fighter” Season 20, “The Tiny Tornado” showed off her trademark style in her UFC debut, cruising past castmate Angela Magana with her ceaseless pressure and combination punching. Despite her 7-0 amateur mark and 5-0 pro mark, the American Top Team fighter is just 25 years old and still has considerable untapped physical potential that should make her a real player in the 115-pound division in the future. Torres will square off against “The Ultimate Fighter 20” castmate Angela Hill at UFC 188 in June.

9. Alexa Grasso (7-0)

Grasso’s fast hands and technical standup got her off to a quick start against Mizuki Inoue at Invicta 11. Despite a late surge from Inoue in the exciting Feb. 27 affair, Grasso took home a unanimous decision, moving the unbeaten Mexican’s record to 7-0. With three straight wins under the Invicta banner, Grasso seems to be closing in on a bout with champion Katja Kankaanpaa.

10. Mizuki Inoue (8-4)

Since claiming Deep Jewels gold in Japan in August, Inoue has lost back-to-back bouts in the Invicta cage, albeit against two of the division’s hottest up-and-comers. The 20-year-old karate stylist dropped a split decision to unbeaten Karolina Kowalkiewicz in November before coming up short on the scorecards once more against Alexa Grasso in February, bringing Inoue’s record in stateside competition to 1-2.

Other Contenders: Stephanie Eggink, Kalindra Faria, Rose Namajunas, Jessica Penne, Livia Renata Souza.
