ESPN's women's pound-for-pound rankings

Who is the world's best women's mixed martial artist, regardless of weight class? My latest top-10 ranking is listed below.

In addition, here is my men's pound-for-pound ranking.

Note: Results through Sept. 18.

= champion

Cris Justino

1. Cris Justino
Record: 18-1
Div.: Featherweight (Invicta FC/UFC)
Last: W (TKO3) Tonya Evinger, July 29, 2017
Next: TBD

The only thing that's been missing from Cyborg's historical career is a UFC championship. She's got that now, and looks as dominant as ever. The question, as always, becomes: Who can the UFC find to challenge this woman?

Joanna Jedrzejczyk

2. Joanna Jedrzejczyk
Record: 14-0
Div.: Strawweight (UFC)
Last: W (UD) Jessica Andrade, May 13, 2017
Next: UFC 217 on Nov. 4, vs. Rose Namajunas

If you consider Jedrzejczyk to be the best female fighter in the world, we certainly won't argue with you. That title comes down to two names and two names only: Jedrzejczyk and Justino. Whether you have Jedrzejczyk at No. 1 or No. 2, the overall point is the same. This woman is the cream of the crop and as close to unbeatable as they come.

Amanda Nunes

3. Amanda Nunes
Record: 15-4
Div.: Bantamweight (UFC)
Last: W (SD) Valentina Shevchenko, Sept. 9, 2017
Next: TBD

It's been an up-and-down year for Nunes, coming off a 2016 campaign that saw her dominate the likes of Miesha Tate and Ronda Rousey. She was forced to pull out of UFC 213 in July, but came back to defend her title against Valentina Shevchenko.

Claudia Gadelha

4. Claudia Gadelha
Record: 15-2
Div.: Strawweight (UFC)
Last: W (Sub1) Karolina Kowalkiewicz, June 3, 2017
Next: UFC Fight Night on Sept. 22, vs. Jessica Andrade

Gadelha has come up short twice to Joanna Jedrzejczyk, but her spotless win over Karolina Kowalkiewicz in June was a reminder of just how talented this Brazilian is. She says she has no plans of fighting in another weight class, that strawweight is her home.

Valentina Shevchenko

5. Valentina Shevchenko
Record: 14-3
Div.: Bantamweight (UFC)
Last: L (SD) Amanda Nunes, Sept. 9, 2017
Next: TBD

Shevchenko's second loss to Amanda Nunes at UFC 215 may haunt her for some time -- as she remains convinced the judges got it wrong up in Edmonton, Canada. Her style is effective, but can lead to close fights. She came out on the short end of this one.

Jessica Andrade

6. Jessica Andrade
Record: 16-6
Div.: Strawweight (UFC)
Last: L (UD) Joanna Jedrzejczyk, May 13, 2017
Next: UFC Fight Night on Sept. 22, vs. Claudia Gadelha

Andrade didn't dethrone Jedrzejczyk at UFC 211, but she put up a more than respectable effort and got her money's worth against the champ in the fifth round. She'll fight for a UFC title again someday. Guaranteed.

Raquel Pennington

7. Raquel Pennington
Record: 9-5
Div.: Bantamweight (UFC)
Last: W (UD) Miesha Tate, Nov. 12, 2016
Next: TBD

Pennington has flown under the radar in the UFC's 135-pound division, and she's scheduled to miss a good chunk of 2017 for shoulder surgery. But her only losses in the UFC have been razor-thin decisions to Jessica Andrade and Holly Holm. She's on the cusp of breaking through to a title shot.

Karolina Kowalkiewicz

8. Karolina Kowalkiewicz
Record: 10-2
Div.: Strawweight (UFC)
Last: L (Sub1) Claudia Gadelha, June 3, 2017
Next: UFC Fight Night on Oct. 21, vs. Jodie Esquibel

Kowalkiewicz's return from a decision loss to Joanna Jedrzejczyk in November turned into a disaster, as she was submitted in just three minutes by Claudia Gadelha in Brazil. No need to write her off after this second setback, but it was definitely not the performance she had envisioned.

Germaine de Randamie

9. Germaine de Randamie
Record: 7-3
Div.: Featherweight (UFC)
Last: W (UD5) Holly Holm, Feb. 11, 2017
Next: TBD

De Randamie remains in the top 10 pound-for-pound rankings, despite being stripped of her UFC featherweight title. She says she's headed back to bantamweight, after refusing to face Cris Justino. And her image is in need of rebuilding.

Rose Namajunas

10. Rose NamajunasRecord: 6-3
Div.: Strawweight (UFC)
Last: W (Sub2) Michelle Waterson, April 15, 2017
Next: UFC 217 on Nov. 4, vs. Joanna Jedrzejczyk

Namajunas has been on a fast track ever since her professional debut. At the age of just 24, she's knocking on the door of her second UFC strawweight title shot after an absolute dismantling of former Invicta FC champ Michelle Waterson.
