RING/WBC flyweight champ Roman Gonzalez and WBA middleweight titleholder Gennady Golovkin advanced in THE RING’s pound for pound rankings after the elite boxer-punchers extended their unbeaten records with impressive knockouts against Edgar Sosa and Willie Monroe Jr.

Both fighters, who co-headlined an HBO-televised doubleheader at The Forum in Inglewood, California, on Saturday, have rapidly climbed the mythical ratings since debuting in THE RING’s top 10.

Gonzalez entered the pound-for-pound rankings at No. 9 in June of 2014, a few months prior to winning the flyweight championship against Akira Yaegashi, which made him three-division titleholder. He advanced to No. 7 and then No. 5 early in 2015 as he improved his record to 42-0 (and Juan Manuel Marquez and Tim Bradley dropped due to inactivity and/or flat performances). The 27-year-old Nicaraguan advanced to No. 4 when Andre Ward was removed for inactivity, and then to No. 3 when Manny Pacquiao dropped after losing to Floyd Mayweather Jr.

Golovkin entered the mythical rankings at No. 10 at the start of the year, advanced to No. 9 after stopped Martin Murray in 11 rounds to notch his 19^th consecutive KOs, and then jumped to No. 7 with Bradley and Marquez moving down to Nos. 9 and 10.

Pound for Pound: Gonzalez, previously rated No. 3, will move up to No. 2, switching places with RING heavyweight champ Wladimir Klitschko. Golovkin advances from No. 7 to No. 4, pushing past the stagnating Guillermo Rigondeaux and the aging Pacquiao and Froch, with his 20^th consecutive knockout. Marquez, who has been inactive for a year, will be dropped from the ratings. Unbeaten WBC bantamweight titleholder Shinsuke Yamanaka will enter at No. 10. The new ratings are:

No.1 Floyd Mayweather Jr. (48-0, 26 KOs)

No. 2 Roman Gonzalez (43-0, 37 KOs)

No. 3 Wladimir Klitschko (64-3, 53 KOs)

No. 4 Gennady Golovkin (33-0, 30 KOs)

No. 5 Guillermo Rigondeaux (15-0, 10 KOs)

No. 6 Manny Pacquiao (57-6-2, 38 KOs)

No. 7 Carl Froch (33-2, 24 KOs)

No. 8 Sergey Kovalev (27-0-1, 24 KOs)

No. 9 Terence Crawford (26-0, 18 KOs)

No. 10 Shinsuke Yamanaka (23-0, 17 KOs)

Cruiserweight: Ilunga Makabu (19-1, 18 KOs) scored an 11^th-round KO over Thabisco Mchunu (17-2, 11 KOs). Makabu will move up two spots to No. 5; Mchunu will drop to No. 10.

Middleweight: Golovkin was too strong and heavy handed for unrated Monroe, who he stopped in the sixth. No change since Golovkin is already our No. 1.

Welterweight: With Marquez, exiting the rankings due to lack of activity, everyone from Nos. 7-10 will move up one spot and Sadam Ali (22-0, 13 KOs) will enter at No. 10.

Junior welterweight: Chris Algieri, who fought his last bout at welterweight (his loss to Pacquiao last November) and will fight his next bout at 147 pounds (against Amir Khan on May 29) will be removed from the 140-pound rankings. Amir Imam (17-0, 14 KOs) will enter the rankings at No. 10.

Junior lightweight: Adrian Estrella (22-1, 20 KOs) was surprisingly stopped in two rounds against Eden Sonsona. Estrella will exit the ratings. Romain Jacob (23-0, 7 KOs) will move up to No. 9 and Ricki Naito (12-0, 5 KOs) will enter at No. 10.

Flyweight: Gonzalez zero’d in on Sosa (51-9, 30 KOs) and quickly made a statement stopping the former 108-pound titleholder in two rounds.
