Saul 'Canelo' Alvarez (56-1-2, 38KOs) recorded career win number 56 on Saturday night, stopping Billy Joe Saunders after eight rounds at the AT&T Stadium in Texas.
The victory saw Canelo add Saunders' WBO super middleweight world title to the WBC and WBA Super championships that he already held. His capture of the WBO belt means Alvarez has now won a staggering 15 world championships (including Ring Magazine titles).
Canelo has now won the following titles during his 16-year, 59-fight professional career:
WBA super welterweight
WBC super welterweight
WBO super welterweight
Ring super welterweight
WBC middleweight (x2)
Ring middleweight (x2)
WBC super middleweight
WBO super middleweight
Ring super middleweight
WBO light heavyweight
Canelo is the second boxer in history to hold world titles in three weight divisions simultaneously. The first to acheive this was the legendary Henry Armstrong, regarded by some as the greatest fighter ever.
It did not take long for Alvarez to call out his next opponent after defeating Saunders. Canelo now holds three of the four recognised world titles at super middleweight - and he wants the final piece of the puzzle before the end of the year.
IBF champion Caleb Plant is the only man standing between Alvarez and total dominance of the 168-pound division. Expected to be back in the ring in September, Canelo wants Plant to be the man in the opposite corner when he does make his return.
