Women’s Strawweight

1. Joanna Jedrzejczyk (11-0)

Jedrzejczyk failed to record a third consecutive knockout but retained her title nonetheless with a gritty and technical five-round decision over Valerie Letourneau at UFC 193. “Joanna Champion” has now defended the UFC 115-pound strap twice since snatching it from Carla Esparza in March and has racked up five Octagon victories in just 16 months under Zuffa employ. After a successful November surgery to repair a broken right hand, Jedrzejczyk will coach on Season 23 of “The Ultimate Fighter” and then defend her belt against Claudia Gadelha in July.

2. Claudia Gadelha (13-1)

Gadelha rudely welcomed Jessica Aguilar to the Octagon on Aug. 1 in a three-round unanimous decision which saw the Brazilian utilizing powerful and precise striking, along with some well-timed takedowns. The win secured a title shot for the Nova Uniao black belt, who will rematch Joanna Jedrzejczyk on July 8 after coaching opposite the champion on the 23rd season of “The Ultimate Fighter.”

3. Jessica Aguilar (19-5)

The former World Series of Fighting titlist was outgunned and outclassed in her Octagon debut, as “JAG” was busted up by Brazilian bruiser Claudia Gadelha at UFC 190. The loss snapped a 10-fight winning streak for Aguilar, who held the division’s top ranking only months ago. She was ticketed for a match with Juliana Lima at UFC 197 on April 23 but had to withdraw after tearing her ACL.

4. Karolina Kowalkiewicz (8-0)

There were no “Octagon jitters” for Kowalkiewicz on Dec. 20, when she put on an impressive and well-rounded performance to claim a unanimous decision against Randa Markos. The unbeaten Polish strawweight silenced the “Quiet Storm” by shutting down nearly all of Markos’ takedown attempts while nearly doubling up on the Canadian in total strikes landed.

5. Livia Renata Souza (9-0)

In her first defense of the Invicta strawweight title, Souza made an impressive statement by blasting through previously unbeaten DeAnna Bennett in just 90 seconds. The Jan. 16 victory was the Brazilian’s first win by way of knockout after submitting seven of her first eight opponents.

6. Valerie Letourneau (8-4)

Letourneau proved tougher competition than most expected for Joanna Jedrzejczyk at UFC 193, where the challenger became the first woman to take the Polish titlist into championship rounds. After a solid start on the feet, however, “Trouble” was gradually busted up by Jedrzejczyk’s crisp striking, and the Canadian’s Octagon winning streak was halted at three.

7. Maryna Moroz (6-1)

Moroz could not consolidate her upset of Joanne Calderwood with a second straight UFC victory, as she wound up on the wrong side of a unanimous decision against Valerie Letourneau on Aug. 23. Still, the 23-year-old Ukrainian boxer holds considerable promise: Moroz finished her first six opponents, five of them inside one round. She will be back in action on April 10, when she takes on UFC newcomer Cristina Stanciu.

8. Tecia Torres (7-0)

Under the bright lights at UFC 194, Torres put on her most impressive showing to date, battering late replacement Jocelyn Jones-Lybarger for 15 minutes with nonstop movement and overwhelming combination striking. The “Tiny Tornado” remains technically unbeaten -- Torres suffered a pair of exhibition losses during her stint on “The Ultimate Fighter” -- and now figures to be only a win or two away from title contention. She will rematch Rose Namajunas at UFC on Fox 19 in April.

9. Joanne Calderwood (10-1)

Fighting before a hometown crowd in Glasgow on July 18, Calderwood survived a first-round assault from last-minute replacement Cortney Casey and pushed back to take a unanimous decision from the UFC debutante. “Jojo” was set for her first headlining slot opposite Paige VanZant on Dec. 10, but a knee injury forced Calderwood to withdraw.

10. Rose Namajunas (4-2)

Despite being early in her career, 23-year-old Namajunas has shown immense promise in just six professional outings. Since losing her bid to become the inaugural UFC 115-pound champion, “Thug Rose” has run off back-to-back submission wins against Paige VanZant and Angela Hill. Namajunas will try to make it three in a row when she rematches Tecia Torres on April 16.

Other Contenders: DeAnna Bennett, Kalindra Faria, Mizuki Inoue, Juliana Lima, Jessica Penne.
