JUNIOR WELTERWEIGHT DIVISION (UP TO 140 POUNDS)
1. Terence Crawford (32-0)
Crawford, the 2014 fighter of the year and former lightweight champion, squared off with fellow undefeated two-belt world titleholder Julius Indongo of Namibia on Aug. 19 in Crawford's home region of Lincoln, Nebraska, on ESPN and Crawford turned in an electrifying performance. He dropped Indongo twice, including with a sensational body punch for a third-round knockout to become the undisputed champion and only the third fighter of the four-belt era to hold them all at the same time. He joined Bernard Hopkins and Jermain Taylor, who both did it in the middleweight division more than a decade ago. Crawford, however, has vacated all of the titles and will move up to welterweight, where he was installed as the mandatory challenger for the winner of the Dec. 13 fight between titlist Jeff Horn and Gary Corcoran. Crawford is expected to challenge the winner in April on ESPN.
2. Julius Indongo (22-1)
In his first fight outside of his home country of Namibia, the heretofore unknown Indongo impressed mightily on Dec. 3 when he traveled to Moscow and scored a sensational one-punch knockout of Eduard Troyanovsky in just 42 seconds to win a world title. It was a devastating overhand left that was reminiscent of Manny Pacquiao's brutal second-round knockout of Ricky Hatton in 2009 in the same division. Indongo then went right into a title unification fight, traveling to Ricky Burns' hometown of Glasgow, Scotland, and easily outpointing him on April 15 to collect another title in a surprisingly easy win. But when he traveled to Lincoln, Nebraska to face fellow unified titleholder Terence Crawford for the undisputed title in his home region on Aug. 19 on ESPN, he got blown out via third-round body shot knockout.
3. Eduard Troyanovsky (27-1)
Russia's Troyanovsky made two successful title defenses but then ran into the unknown Julius Indongo, a 2008 Olympian from Namibia, and shockingly got knocked out in 42 seconds December 2016. He made his return on July 1 against former title challenger Michele Di Rocco, of Italy, and looked good as he scored four knockdowns -- all with right hands -- en route to a fourth-round knockout victory. And on Nov. 27, in Moscow, he knocked out Paraguay's then-unbeaten Carlos Manuel Portillo in the first round of a world title elimination bout.
4. Antonio Orozco (26-0)
San Diego's Orozco, who fights in a relentless, fan-friendly style, headlined the April 1 "Golden Boy Boxing on ESPN" card and looked terrific in a fourth-round knockout of previously undefeated KeAndre Gibson. Orozco's next fight was supposed to be on the Jorge Linares-Luke Campbell undercard on HBO against Mexico's Roberto Ortiz on Sept. 23, but Orozco badly missed weight and had a bout canceled 24 hours ahead of time. It was the second time in his past three scheduled fights that Orozco had a bout canceled because of a failure to make weight. Obviously, he should not be at junior welterweight any longer. He's killing his career with such irresponsible behavior.
5. Sergey Lipinets (13-0)
Lipinets, a native of Kazakhstan fighting out of Los Angeles earned a mandatory shot at unified titleholder Julius Indongo when he knocked out Lenny Zappavigna in the ninth round of their elimination fight in December 2016. Once Terence Crawford knocked out Indongo, Lipinets became one of his mandatory challengers, but with the fight due Crawford vacated one of the belts. That left Lipinets to fight for a vacant title against Japan's Akihiro Kondo on Showtime on Nov. 4, when Lipinets won a close decision in a grueling fight. His mandatory challenger will be the winner of an upcoming eliminator between Ivan Baranchyk (17-0) and Hiroki Okada (16-0) though Lipinets has been one of the names mentioned as a possible next opponent for Mikey Garcia (37-0).
6. Felix Diaz (19-2)
Diaz, who won an Olympic gold medal for the Dominican Republic in 2008, is a very good fighter and deserved the long sought-after shot at unified world champion Terence Crawford he got on May 20. However, Crawford is superb and dominated Diaz in a one-sided fight that ended after the 10th round when Diaz's trainer, Joel Diaz, did the right thing and stopped the fight.
7. Regis Prograis (20-0)
Prograis, with good skills and power, has been making his way up the ladder for the past few years but made a major statement on June 9 when he dropped then-unbeaten Joel Diaz Jr. four times in a second-round knockout victory in the main event of Showtime's "ShoBox: The New Generation." Prograis' biggest issue now is going to be convincing top opponents to fight him though he has been ordered to face former titlist Viktor Postol (29-1) for an interim title.
8. Rances Barthelemy (26-0)
Cuban defector Barthelemy, a former junior lightweight and lightweight world titleholder, moved up to junior welterweight and won a debatable unanimous decision against Belarus' Kiryl Relikh (21-2) in a May 20 title eliminator. They've been ordered to meet in a rematch for a now-vacant world title.
9. Adrian Granados (18-6-2)
Chicago's Granados, who scored a massive upset of Amir Imam in 2015 to knock him out of a mandatory title shot, has a deceiving record. Five of his six his losses are either by majority or split decision, including an action-packed Feb. 18 welterweight fight against friend and former titlist Adrien Broner, who edged him by split decision in a fight that could have gone either way. But in his next fight, on Showtime on Nov. 4, there was no doubt about the outcome as Shawn Porter soundly outpointed Granados in a bout at welterweight.
10. Ricky Burns (41-7-1)
The former junior lightweight and lightweight titlist knocked out Italy's Michele Di Rocco in the eighth round in May 2016 to win a vacant 140-pound belt, making him the first fighter from Scotland to win world titles in three weight classes. He lost the belt in his second defense, dropping a lopsided decision in a unification fight with Namibia's Julius Indongo. In his next fight, Burns dropped back to lightweight to take on former lightweight titlist Anthony Crolla, of England, in Oct. 7 and lost a competitive decision in a spirited fight.
