Boxing Rankings, January 2013: Marquez takes top spot at welterweight, new female pound-for-pound

New month! New rankings! A few new No. 1 fighters!

Below are the changes, and here's the full rankings page:

Heavyweight

Steve Cunningham (25-5, 12 KO) enters the rankings at No. 8, fresh off of a "controversial" or "highly questionable" or "highway robbery" decision loss to Tomasz Adamek on December 22. Falling out is Dereck Chisora, who was previously ranked No. 9.

Welterweight

With his move up and crushing defeat of Manny Pacquiao, current divisional floater Juan Manuel Marquez (55-6-1, 40 KO) goes from No. 1 man at 140 to No. 1 man at 147. The 39-year-old Marquez was and still is the oldest top-ranked fighter in the sport.

The 2-3 spots should still cause braineurysms or somethin', as Timothy Bradley is the new No. 2 and Manny Pacquiao is No. 3. We know, we know. We discussed it last month. Live and let die, as Guns n' Roses so famously sang. (I know, I know.)

Carson Jones, ranked eighth last time out, is out after his draw with Dean Byrne. Paulie Malignaggi and Jan Zaveck flip in the 9-10 slots.

Junior Welterweight

Two fighters are out, as ex-No. 1 Marquez is not ranked at welterweight, while IBF titlist Lamont Peterson went inactive. Sometimes I might say, "Hey, he just scheduled a fight, let's keep him ranked," but two things: 1) That fight was signed after we put our rankings together, and 2) Peterson arguably shouldn't even have been ranked anyway, so woopty doo. If he beats Kendall Holt on February 22, he'll be back.

Danny Garcia, of course, is your new No. 1 man in the division. New to the rankings are Karim Mayfield and Olusegun Ajose, who noses past Ruslan Provodnikov.

Super Featherweight

The top two remain the same, with Takashi Uchiyama and Juan Carlos Salgado locked in, but Yuriorkis Gamboa has returned to the ring and joined the party at a somewhat cautious No. 3, following a rocky but still clear win over Michael Farenas on December 8. Falling out is previous No. 10 Takahiro Ao.

Featherweight

Celestino Caballero has been removed due to one year of inactivity, and Hozumi Hasegawa is also out, as he's trying to move back to super bantamweight, and, well, he was an arguable ranking anyway. Nicholas Walters (22-0, 18 KO) and Javier Fortuna (21-0, 15 KO) move into the 9-10 spots.

Super Bantamweight

1-2-3 is settled for the time being: Donaire, Mares, and Rigondeaux have those spots cemented. But Jorge Arce's blowout loss to Donaire and subsequent retirement means he's out of the rankings, so it becomes a mish-mash of the proven and the hopeful after that.

The hopeful would be Scott Quigg (6) and Carl Frampton (9), and perhaps to a lesser extent, ex-titlist Rico Ramos (8). You also have veterans Jeffrey Mathebula (4) and Wilfredo Vazquez Jr (5), both already downed convincingly by Nonito, and then Victor Terrazas (7) and Vic Darchinyan (10), who replaces Arce in the rankings, edging out Alexander Bakhtin. It was a lively division in 2012, but we've come to an obvious conclusion: Donaire, Mares, and Rigondeaux need to fight each other, somehow, some way.

Flyweight

Giovani Segura, previous No. 10, is out due to inactivity. Milan Melindo takes his place, with some very mild shake-ups otherwise, back-end guys trading spots or the like.

Female Pound-For-Pound

This is new, compiled by Ryan. He's also doing the 105/108 men's divisions alone now, because he knows the divisions much better than I do, so I'm just handing that over to him entirely from here on.
