SAUL "CANELO" ALVAREZ returns to action this weekend when he meets fellow Mexican Alfredo Angulo in Las Vegas.
The flame haired Mexican last boxed in September when he was outclassed over 12 rounds by Floyd Mayweather Jr in a contest many tipped him to win.
Alvarez is fancied to overcome heavy handed Angulo, but needs an impressive win to prove he has recovered from his only career defeat.
BoxNation looks at how much ring success Mayweather's ten opponents before Alvarez had after they had been dominated by the world's number one boxer.
The omens are not good for Alvarez who has already had 44 professional contests and is just 23 years old.
There has been a few great wins, but plenty of high profile losses for Floyd's victims since losing to him. There combined records since losing to Floyd are 25-22-1
Guerrero hasn't boxed since being outclassed by Mayweather last May. There is talk he could face Amir Khan on May 3 on the Mayweather-Maidana undercard.
The Puerto Rican great gave a good account when losing on points to Mayweather in May 2012. He lost to Austin Trout on his return, but thrashed high end club fighter Delvin Rodriguez in three rounds last October. He faces Sergio Martinez in June when we might see whether Mayweather finished him off as a top class boxer.
Ortiz's career has nose-dived since being KO'd in four by Mayweather in a foul infested fight back in September 2011. Since then, he suffered a broken jaw and was forced to retire after nine rounds against Josesito Lopez, and a second round loss against Luis Collazo last month possibly ended Ortiz's 36 fight career.
Old stager Shane is still rolling on, but done nothing of note since his points loss in May 2010 - going 1-3-1. His only win came last May against fringe contender Pablo Cesar Cano, beating him 115-113 on all three cards. He barely won a round against Manny Pacquaio and Saul Alvarez. He recently lost in seven against Anthony Mundine.
JUAN MANUEL MARQUEZ
The brilliant Mexican was too small to give Mayweather any test and went down on points in September 2009. He is 5-2 since then losing to controversially to Manny Pacquiao and then to Tim Bradley last October. In December 2012 he met 'Pacman' for the fourth time and finally toppled him with a sixth round KO.
Hatton was 43-0 when he was hammered in ten rounds by Mayweather, and his career never truly recovered afterwards despite a good stoppage win over Paulie Malignaggi. He barely beat Juan Lazcano, but was horribly beaten by Manny Pacquiao. When he returned after three years in November 2012, Ricky lost in nine against Vyacheslav Senchenko on one of British boxing's saddest nights.
OSCAR DE LA HOYA
Mayweather had his toughest night when he got a split decision win over Oscar in a fight that did record breaking numbers in May 2007. De La Hoya beat Forbes in his comeback a year later, but his career was famously finished off by Manny Pacquiao. He has also had outside issues.
The Argentine had lost nine times before he was virtually shut-out by Mayweather, but had been on an unbeaten 21 fight streak and defeated Arturo Gatti in his previous bout. He hasn't boxed since 2012, but in contests since Floyd is 6-5 and not registered a significant win.
Judah has boxed 14 times since losing on points against Mayweather in April 2006. He did briefly hold the IBF light-welterweight title in 2011, but Amir Khan took that in his first defence and seems to come unstuck when he fights the best. Miguel Cotto, Joshua Clottey, Danny Garcia and Paulie Malignaggi have all beaten him since the Floyd loss.
He had been hammered by Kostya Tszyu two fights before Mayweather stopped him in six rounds back in November 2005. Mitchell had just two more bouts after, outpointing Jose Luis Cruz before 30-0 Paul William knocked him out in four rounds.
