JUNIOR LIGHTWEIGHT DIVISION (UP TO 130 POUNDS)
1. Vasyl Lomachenko (9-1)
Lomachenko, the brilliant two-time Olympic gold medalist from Ukraine, is viewed by some as the best fighter in the world pound-for-pound. He made his first junior lightweight title defense against former featherweight titleholder Nicholas Waters and dominated and befuddled him, so much so that Walters simply quit after the seventh round. Lomachenko returned April 8 and laid waste to former titlist Jason Sosa in nine massively one-sided rounds. And then on Aug. 5 on ESPN Lomachenko faced Colombian puncher Miguel Marriaga, a two-time featherweight title challenger, and dominated again, dropping him twice and stopping him in the seventh round. Next up will be a summit meeting with another two-time Olympic gold medalist, Cuban junior featherweight titlist Guillermo Rigondeaux (17-0), who is moving up two weight classes. They'll fight on a Top Rank ESPN card at the Theater at Madison Square Garden.
Next: Dec. 9 vs. Rigondeaux
2. Miguel Berchelt (32-1)
On July 15, Berchelt made his first defense against mandatory challenger and former titlist Takashi Miura, of Japan, and won a near-shutout decision in a fight not nearly as competitive as most expected. Defense No. 2 will take place on a date to be determined in December on HBO against Mexican countryman and former titlist Orlando Salido (44-13-4) in a fight that figures to produce excellent action.
Next: TBA vs. Salido
3. Jezreel Corrales (22-1)
In a huge upset, then-interim titlist Corrales, a southpaw from Panama, traveled to Tokyo and scored three knockdowns against long-reigning titleholder Takashi Uchiyama in the second round to win the full title in April 2016. In the December rematch, also in Tokyo, Corrales came away with a split decision victory. Then he signed with Golden Boy Promotions and made his American debut on July 15 on HBO, retaining the belt by very close decision against Robinson Castellanos. Corrales will be back on HBO to defend against Puerto Rico's Alberto Machado (18-0).
Next: Oct. 21 vs. Machado
4. Gervonta "Tank" Davis (19-0)
Davis, a dynamic fighter from Baltimore and a Floyd Mayweather protégé, was very impressive on Jan. 14 when he stepped up in competition and stopped Jose Pedraza in the seventh round of an excellent fight to win a world title. He was equally as impressive in his first defense on May 20, when he was in England, with Mayweather at ringside, and destroyed mandatory challenger Liam Walsh in a third-round knockout victory. But he was not close to that in his next fight on Aug. 26, when he was overweight by two pounds, stripped of his belt and then turned in a middling performance in an eighth-round knockout of Francisco Fonseca on the Mayweather-Conor McGregor undercard.
5. Orlando Salido (44-13-4)
Mexico's Salido, a former featherweight and junior lightweight titleholder, has been in numerous fight of the year candidates and become a fan favorite for good reason. In his latest incredible action fight, Salido battled to a draw challenging titleholder Francisco Vargas in June in the 2016 ESPN.com fight of the year. He returned from an 11-month layoff May 27 to knock out late replacement Aristides Perez, of Colombia, in the eighth round, but not before suffering a third-round knockdown. After various fights fell through for different reasons, Salido is slated to challenge countryman Miguel Berchelt (32-1) for his world title on HBO in December. That's a can't miss action fight.
Next: TBA vs. Berchelt
6. Francisco Vargas (23-1-2)
Vargas -- the Mexican Arturo Gatti -- won the 2015 fight of the year in an epic comeback knockout of Japan's Takashi Miura to win a world title and drew with former titlist Orlando Salido in the 2016 fight of the year in his first defense. But both fights were absolutely brutal and Vargas took tremendous punishment. He suffered bad cuts in both fights which came back to haunt him in his second defense on Jan. 28, when he faced countryman Miguel Berchelt in an HBO main event. It was, of course, another action-packed fight, but Berchelt took over in the later rounds after opening terrible cuts around both of Vargas' eyes. His skin just cannot hold up under the assault and Berchelt won by 11th-round knockout. Vargas, who has been ordered to face countryman Jhonny Gonzalez (64-10) in a title eliminator, aims to return to action before the end of the year.
7. Robinson Castellanos (24-13)
Mexico's Castellanos, an upset specialist, pulled a big one in May when he knocked out former featherweight titlist Yuriorkis Gamboa in the seventh round of a one-sided fight. The win propelled him into a world title shot against Jezreel Corrales on July 15 on HBO. It was a highly competitive fight as Castellanos scored two fourth-round knockdowns and was also dropped in the seventh round. Ultimately, Castellanos lost a very tight 10th-round technical majority decision when it was stopped after Castellanos suffered a bad cut from an accidental head butt. Castellanos will face Jason Sosa (20-2-4) on HBO on the Sergey Kovalev-Vyacheslav Shabranskyy card with the winner promised a title shot in 2018.
Next: Nov. 25 vs. Sosa.
8. Jason Sosa (20-2-4)
Sosa made the first defense of his secondary belt in November 2016, traveling to Monte Carlo and outpointing England's Stephen Smith in a fantastic slugfest. Sosa then gave up his belt to facilitate a fight nobody else seemed to want against the outstanding titleholder Vasyl Lomachenko on April 8. However, Sosa, as most predicted, was completely outclassed in a ninth-round knockout loss. His return will come against Mexico's Robinson Castellanos (24-13) on the Sergey Kovalev-Vyacheslav Shabranskyy HBO card.
Next: Nov. 25 vs. Castellanos.
9. Jose Pedraza (22-1)
Nicknamed "Sniper," Puerto Rico's Pedraza rolled to a shutout decision against Russia's Andrey Klimov to win a vacant belt in June 2015. He did not look nearly as good in his first defense, getting a gift split decision against battle-tested Edner Cherry, though looked much better in a unanimous decision against mandatory challenger Stephen Smith in defense No. 2. But then things went downhill again on Jan. 14 when Pedraza lost the belt to Gervonta Davis by punishing seventh-round knockout on Showtime.
10. Tevin Farmer (25-4-1)
Philadelphia's Farmer, a southpaw, has won 18 fights in a row, including victories against former titlist Gamaliel Diaz and Ivan Redkach, since an eight-round knockout loss to former world titlist Jose Pedraza in 2012. Farmer will return from a gunshot wound to his hand to face Japan's Kenichi Ogawa (22-1) for a vacant title on an HBO undercard in December.
Next: TBA vs. Ogawa.
