Kenshiro Teraji showed poise and the skills which previously saw him a fixture on pound-for-pound lists as he outboxed Israel Gonzalez to the tune of a 12-round decision for the WBO junior bantamweight strap on July 20.

His impressive win at Tokyo's Ryogoku Kokugikan was sandwiched between a gutsy 11th-round stoppage win for WBC junior flyweight champion Shokichi Iwata against then-unbeaten challenger Erik Badillo. An even more tense main event tussle saw Riku Masuda continue his fine form, beating the returning Daigo Higa over 12 rounds.

While many were focused on heavyweight action in Asia and the Middle East, an unfortunate weight mishap saw former two-division beltholder Stephen Fulton (23-2, 8 KOs) fail to compete, let alone deliver in a proposed 130-pound WBA title eliminator against Liam Wilson on the Errol Spence-Tim Tszyu undercard in Sydney, Australia.

Former WBO 154-pound champion Tszyu still has work to do, if he's to crack into the top 10 after declaring middleweight was his new home following a career-best win over Spence, who retired post-fight at the weekend.

IBF junior middleweight titleholder Josh Kelly was made to work for a gritty 12-round decision win during his first title defense against Caoimhin Agyarko, though didn't do enough in Saudi Arabia to warrant movement as rising pound-for-pound force Jaron "Boots" Ennis continues to circle the Brit for an in-house title unification.

On a night where two attractions ended year-long layoffs, Edgar Berlanga is calling for big fights once again after climbing off the canvas to stop Steven Butler in their Zuffa Boxing 09 headliner.

Though it was his longtime friend and promotional stablemate Richardson Hitchins who produced a shutout against Ricardo Salas, while nursing a hand injury, prompting a shake-up across two weight categories. Six different divisions saw changes, big and small, this week, so scroll down to read the breakdown.

Hitchins' points win sees him enter the bottom half of a loaded 147-pound division, leapfrogging two-division champion and former foe Paro into the No. 9 spot. Lewis Crocker, who Paro beat last month, drops out.

The aforementioned 28-year-old's departure from junior welterweight means all but two contenders move up a place at 140 pounds. Lopez is sure to join him after next month's WBA title fight with Rolando Romero.

Fulton's big weight miss at junior lightweight means he drops out of the 126-pound class with a whimper, while Venezuelan spoiler Parra — who drew with Trinidad last year and stunned Elijah Pierce, enters at No. 10.

Masuda rises two places to No. 4 at 118 pounds, a spot above WBO champion Medina. Meanwhile, Higa dropped one place though confirmed he will not be retiring after another agonising defeat at the elite level.

Three-division champion Teraji rises into the top-half of a division previously ruled by Jesse "Bam" Rodriguez, with four contenders below him all making way.

Iwata rises two spots to No. 3 after an impressive title defense, while Badillo falls furthest: three places and sits at No. 10 after suffering a harsh lesson at world level.
