A stroll through the MGM Grand reveals why, decades after the city was coined with the moniker, Las Vegas remains the Fight Capital of the World.

Boxing fans have overtaken the third largest hotel in the world. It’s been a while since a match of this magnitude took place.

It’s been even longer since tonight’s headliner, Floyd Mayweather Jr., has been involved. Mayweather (43-0) looks to stay undefeated with a victory against Robert Guerrero at the MGM Grand Garden Arena.

Guerrero’s chances have been widely debated, and even called into question by Mayweather, but there’s an undeniable truth about “The Ghost”: He deserves this opportunity.

Winner of 15 straight and holder of the WBC interim welterweight title, Guerrero doesn’t lack for confidence. And neither do his supporters.

Mexican flags are widespread throughout the MGM Grand, and those holding them aren’t shy about sharing why Guerrero could pull off the shocker tonight.

But they pale in comparison to those with “The Money Team” and “Mayweather Boxing Club” shirts.

Pictures of Mayweather and Guerrero are plastered everywhere throughout the casino. They’re on under-construction walls, blackjack tables and slot machines — pretty much everything except the floor.

And that might be just because Mayweather doesn’t let anyone walk over him. Likely the best defensive boxer in the history of the sport, Mayweather rarely gets touched.

Mayweather took more shots than usual in his last fight, a unanimous-decision victory over Miguel Cotto, and has never forgiven himself. He’s refined some of his training and reunited with his father, Floyd Mayweather Sr., in an effort for a better performance this time out.

Guerrero’s father is also an important figure in his fight career. The only lost Robert Guerrero ever lost came during a brief stint when he trained with someone other than Ruben Guerrero.

Guerrero says any adjustments Mayweather made are meaningless. He could beat him either way.

It’s a bold statement going up against a fighter who’s never lost in a 17-year career. The packed arena is about to find out if Guerrero can live up to the vows, as the fighters’ entrances are a couple hours away.

Stay tuned to for a live round-by-round blog of the Mayweather vs. Guerrero action and updated results from the pay-per-view undercard below.

Abner Mares added another title to his arsenal — the WBC featherweight belt — in the evening's co-feature. Mares beat friend and former training partner Daniel Ponce de Leon by TKO at 2:20 of the ninth round. Mares had dropped Ponce de Leon twice before the finish when he pelted him with a combination against the ropes.

Leo Santa Cruz defeated Alexander Munoz by TKO at 1:05 of the fifth round of a featherweight fight. Cruz got his first knockdown in the third round. Munoz's corner had seen enough when Cruz dropped their fighter with another combination in the fifth.

The controversial decisions have already begun as Las Vegas' J'Leon Love defeated Philadelphia's Gabriel Rosado by split decision (97-92, 95-94, 94-95) in a middleweight bout. The crowd loudly booed when the scores were read. Las Vegas Sun scored the pay-per-view opener 96-93 in favor of Rosado.
