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 was supposed to be against Mexican countryman and former titlist Orlando Salido (44-13-4) on Dec. 9 on HBO but Berchelt suffered a right hand injury and the fight was called off.
3. 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.
4. 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 has 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 was slated to challenge countryman Miguel Berchelt (32-1) for his world title on HBO on Dec. 9 until Berchelt injured his right hand. So instead Salido will headline against countryman Miguel "Mickey" Roman (57-12).
Next: Dec. 9 vs. Roman
5. Alberto Machado (19-0)
Puerto Rico's Machado, a southpaw trained by Hall of Famer Freddie Roach, got knocked down in the fifth round and was trailing on all three scorecards against Jezreel Corrales in their Oct. 21 HBO fight. But in the eighth round, Machado stormed back and knocked him out to win the vacant title that had been stripped from Corrales for failing to make weight. Machado has been ordered to next make a mandatory defense against Ghana's Rafael Mensah (31-0), who has never faced an opponent remotely resembling a top fighter.
6. Jezreel Corrales (22-2)
Corrales, a speedy southpaw from Panama, won his title in upset fashion against long-reigning titleholder Takashi Uchiyama by second-round knockout in April 2016. He beat Uchiyama by decision in a rematch and then signed with Golden Boy Promotions and made his American debut on July 15 on HBO. He retained the belt by very close decision against Robinson Castellanos. But before his next defense on Oct. 21, also on HBO, Corrales was stripped for missing weight against Alberto Machado. The fight went on anyway and Corrales dominated, even dropping Machado in the fifth round. But Machado rallied and scored an out of nowhere knockout in the eighth round to win the vacant belt.
7. 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 will make his return on HBO against former title challenger Stephen Smith (25-3) on the Orlando Salido-Miguel Roman undercard.
Next: Dec. 9 vs. Smith.
8. 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 was due back to face former titlist Jason Sosa (20-2-4) on HBO on Nov. 25 on the Sergey Kovalev-Vyacheslav Shabranskyy card but Castellanos suffered a back injury and had to pull out.
9. 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.
Next: Dec. 9 vs. Ogawa
10. Jason Sosa (20-3-4)
Sosa vacated a secondary belt in early 2017 to facilitate a fight chance to challenge 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 on HBO on the Nov. 25 Sergey Kovalev-Vyacheslav Shabranskyy card, but his opponent, Mexico's Robinson Castellanos (24-13), pulled out with a back injury. So Sosa faced late replacement Yuriorkis Gamboa, the faded former featherweight titlist Castellanos made quit earlier in the year. Sosa looked good, scored a knockdown and appeared to do enough to win but was robbed via majority decision.
