Oddsmakers have Mayweather a 6-1 favorite against a fighter who moved up to welterweight just two fights ago and got the fight mainly on his impressive win in his last outing against Andre Berto. Guerrero — who won two world titles at 126 pounds and another at 130 — will get $3 million for the fight, but understands the rewards for being the first one to beat Mayweather would be a lot more.
‘‘A lot of people underestimate how strong I am in the ring. People underestimate my strength and it really is a big downfall for them,’’ Guerrero said. ‘‘You have a strong body, you have fast hands, you have heavy hands and you have the skill and talent to put things together and be able to change up things in the ring. It really is a game changer for a fighter.’’
Both fighters will have their fathers in the corner, with Mayweather bringing back his after a long absence. Floyd Mayweather Sr. is replacing Roger Mayweather, who has been in his nephew’s corner for 13 years. Mayweather said his uncle’s diabetes makes it hard for him to see now, and he needs someone in the corner who can help him make adjustments.
Ruben Guerrero trains his son, and injected some spark into the prefight buildup with his tirade at the press conference. Ruben Guerrero and Floyd Mayweather Sr. then began jawing at each other before being separated.
On Saturday night, they'll be confined to their corners. Their sons will be the ones doing the fighting.
