ESPN's divisional boxing rankings highlight the best in the sport in every weight class. They will change often, based on recent results and performances. Rankings are based on what a fighter has accomplished in the weight division in which he is ranked. Fighters who have announced they are moving to a different weight class will be ranked in that new division, if warranted, only once they fight in that weight class. Fighters who currently own titles in two divisions can be ranked in both.
Fighters who haven't competed in the past 12 months -- and don't have a fight scheduled -- will be dropped from the rankings until they fight again. Any fighter who tests positive for a performance-enhancing substance will also be removed. That boxer will be eligible to re-enter the rankings after his next bout.
Fighting for the first time since a controversial loss to Devin Haney a year ago, Vasiliy Lomachenko returned to the ring in Perth, Australia, on Saturday (Sunday morning in Australia) to reclaim one of his lightweight titles.
Lomachenko (18-3, 12 KOs) was his former self in a dominant victory over fellow former champion George Kambosos Jr. to win the vacant IBF title. He started fast and never let down until he dropped Kambosos with 30 seconds to go in Round 11 with a body punch. Kambosos (21-3, 10 KOs) recovered enough to beat the count, but seconds later his corner threw in the towel to end the fight.
With the victory, Lomachenko solidifies his No. 1 spot in the 135-pound division, while Kambosos drops three spots to No. 8 after the loss.
On the same card, Pedro Guevara scored an upset split-decision victory over Andrew Moloney to win the WBC interim junior bantamweight title.
Guevara (42-4-1, 22 KOs) won by scorecards of 115-113, 115-113 and 113-116 in his second chance at the title. He lost a split decision to Carlos Cuadras in November challenging for the same belt.
Moloney (26-4, 16 KOs) has lost two of his last three fights. He said he injured his biceps ahead of the fight, and was very disappointed with the result, saying he was retiring.
"I tore my bicep eight days out from the fight, and I can jab perfectly, so that's why I stuck behind and jabbed the whole fight and I thought if I need to throw my hook, I can, it's there. If I need it, I'll dig deep. But I didn't even feel like I needed to bring it out because I was in total control. I just can't believe, I dunno how anyone can see that he's won that fight. The only way you can see him win that fight is by corruption, and that's all I can say.
"Honestly, I should say I'm shocked, but I've been here before in this sport, it's corrupt as anything. ... I thought at max I lost two rounds, and I should have been walking home with that belt. I've given my life to this sport for 20 years. That's twice they've ripped me off for a world title. And I thanked Top Rank, I thanked my whole team, but I'm done with this sport because it's corrupt and I can't do anything more than I already am, so I'm out."
Guevara enters the rankings at No. 10, while Moloney falls out.
Rankings are determined by Mike Coppinger, Nick Parkinson, Damian Delgado Averhoff and Andres Ferrari. They are updated weekly on Tuesdays.
