SAUL ‘CANELO’ ALVAREZ attempts to join the list of legendary Mexican fighters who have won world titles in four weights.
The current unified middleweight king jumps two divisions on Saturday facing WBO champion Sergey Kovalev in Las Vegas.
If successful Canelo will be accompanied by legendary Mexican’s Erik Morales, Juan Manuel Marquez, and Jorge Arce as four-division world champions.
Having started his career at 15, Alvarez fluctuated in weight even fighting at the light-welterweight limit of 140lbs before settling in at welterweight.
Winning his first world title at light-middleweight, SunSport investigates the dramatic body transformation Canelo has been through in his 55-fight career.
After 33 bouts Alvarez made his US debut on October 2008 beating Larry Mosley and recorded another win Stateside before returning back to Mexico for two years and nine fights.
When he returned he defended his NABF welterweight title against Jose Cotto in what turned out to be his last contest at 147lbs.
Canelo first won a world title at 154lbs beating Ricky Hatton’s brother Matthew in California.
The Mexican won a points decision but was much trimmer in frame and bulk with a baby face.
He would make five defences of the WBC belt before unifying against Austin Trout in April 2013 also claiming the WBA strap.
At aged 23 Canelo would defend his light-middleweight titles against ring legend Floyd Mayweather – but was made to suffer on the scales.
Mayweather only moved up from welterweight to face Oscar De La Hoya and Miguel Cotto, but did so once again to challenge rising star Canelo in September 2013.
But the American boxing great – who promoted and managed himself – proved he is a veteran of the business side of the sport by forcing Alvarez to contract stipulations.
The Vegas bout was made at a catchweight of 152lbs, meaning the champion had to lose an extra two pounds – and Canelo claimed Mayweather even tried to put a rehydration clause in the contract.
Mayweather reportedly weighed 150lbs, below weight, and Alvarez came in at 165 pounds, putting on almost a stone – but was still outpointed by his American rival.
Canelo moved up to middleweight two years after his first defeat, and learned from Mayweather on how to use his star power.
Despite campaigning in the 160lbs division, the Mexican hero forced his opponents to fight at a catchweight of 155lbs, first winning the The Ring, Lineal, and WBC titles against Cotto.
Brit Amir Khan even moved up to middleweight to fight Canelo at 155lbs, but was brutally KO’d in six rounds before Alvarez moved back to light-middleweight to win the WBO title from Merseysider Liam Smith.
He only dropped back to 154lbs after being mandated by the WBC to face Gennady Golovkin, but promoter De La Hoya insisted his man was not yet a true middleweight.
Julio Cesar Chavez Jr
Canelo beat Smith for the WBO belt in his final fight at 154lbs.
Despite De La Hoya claiming the Mexican was not yet ready to box at 160lbs, one fight later Alvarez would face Julio Cesar Chavez Jr in a 164.5lbs catchweight bout – ABOVE the middleweight limit.
The fight was used as a tester before Canelo matched up against middleweight rival GGG, as Chavez Jr was easily outpointed.
After two contentious results against Golvokin at middleweight – that saw Canelo walk away with a draw and win – he announced a move up to 168lbs to face Brit Rocky Fielding.
The Mexican would challenge for the WBA’s understudy super-middleweight world title, which he won with ease in three rounds.
Canelo was much the smaller man but targeted Fielding’s body to win a world title in his third weight, and then revealed he would be open to fighting world champion Callum Smith.
After winning a super-middleweight belt, WBC and WBA middleweight champion Canelo returned to 160lbs, facing Daniel Jacobs with the IBF title also on the line.
Alvarez’s move back down eight pounds did nothing to dent his reflexes and power as he put on a great display of defence and aggression on the way to a points win.
Canelo stuck with the IBF’s 170lbs rehydration clause, but Jacobs did not, meaning he lost the belt on the scales after coming in at 173.6lbs for tactical reasons.
After adding another middleweight belt to his collection Alvarez decided not to defend them against rival Golovkin in a trilogy bout.
Instead he will look to replicate US legends such as Roy Jones Jr, Bernard Hopkins and Sugar Ray Leonaerd who all won 175lbs titles.
Canelo has even claimed he will stick around at the weight to face another devastating Russian, Artur Beterbiev, who just moved to 15-0 by knocking out Oleksandr Gvozdyk to reign as WBC and IBF champion.
Jones Jr was the only boxer ever to go from middleweight to heavyweight champion, after he dethroned John Ruiz in 2003 to become WBA champion, but skipped over cruiserweight.
He vacated his heavyweight title straight away, moving back down to light-heavyweight, and later in his career campaigned at cruiserweight, but never for a world title.
