Mayweather vs. Berto Fight: Start Time, PPV Coverage Info and Preview

World-class boxers have tried and failed to defeat Floyd "Money" Mayweather Jr. on 48 different occasions, but Andre "The Beast" Berto is hopeful that the 49th time will be a charm Saturday night.

Berto enters the contest with low expectations and plenty of negativity being thrown in his direction due to the notion that he isn't a worthy opponent in what Mayweather says will be his last fight. It certainly isn't Berto's fault that he was ultimately chosen, but he has a golden opportunity to silence the naysayers with a fine performance.

There is no guarantee that Berto will come out on top even if he's at his best, but he has a chance to make it a good, exciting contest thanks to his pure punching power. By the same token, Mayweather promises to do everything in his power to ride off into the sunset with an undefeated mark.

Here is everything you need to know about when and where to watch the fight, as well as a preview and predictions for the upcoming clash.

Where: MGM Grand Garden Arena in Las Vegas

What Mayweather's Saying

Mayweather enters Saturday's fight as a massive favorite, which is a position he is used to. Losing to Berto would be an absolute shock within the boxing community, but Mayweather has made it clear he believes his opponent is dangerous.

Fighters of Mayweather's caliber may find it easy to take opponents lightly at times; however, Mayweather's comments suggest he is wary of what Berto brings to the table.

According to Showtime Sports, he believes Berto has what it takes to challenge him in the supposed final fight of his career:

Mayweather also feels as though Berto is somewhat comparable to his last opponent, Manny Pacquiao, despite the obvious gap in terms of the quality if their resumes, per Reuters (h/t the Guardian):

"The difference between Berto and Pacquiao is you guys put all the hype in Manny," Mayweather said. "But this fight is a very intriguing matchup. ... Have you ever seen a boring Andre Berto fight? Every time I fight it's exciting. Every time Pacquiao fights it's exciting."

Many have questioned not only the quality of Mayweather's opponent, but also his sincerity with regard to retirement. Money previously retired and came back, but he insists that this time will be different, according to the Associated Press (h/t ESPN.com):

"They say they'll offer me a lot of money to keep fighting," Mayweather said. "I have a lot of money. I'm OK. ... It's the end of my (Showtime) deal. I'm an old man now. I'm 38."

Mayweather calling this a retirement match could just as easily be a ploy to generate pay-per-view interest and buys, but it's entirely possible that he's telling the truth because there isn't much left for him to accomplish in boxing.

He has done it all, and if he is able to defeat Berto to move to 49-0, then he can walk away from the sport knowing he is among the all-time greats.

What Berto's Saying

In one respect, Berto is in a tough spot because few believe he can give Mayweather a true challenge. At the same time, though, he enters the contest with little pressure, which could allow him to go after Mayweather with reckless abandon.

Berto has heard time and again during the lead up to the fight that he isn't up to the task of facing Mayweather, but that has seemingly motivated him to turn in the best possible performance:

There is no question that Berto has struggled as of late, having lost three of his past six fights, but he was 27-0 before that stretch, and many considered him to be one of the most dynamic and dangerous boxers in the world at that point.

Although he recently has had trouble putting all the pieces together, Berto still has a skill set that can give even the best fighters some issues. According to Showtime Sports, Berto believes he has everything needed to be a real threat to Mayweather:

Because 70 percent of Berto's victories have come via knockout, the 32-year-old underdog promises to be aggressive. That has gotten him into trouble before, and it could ultimately lead to his demise against the savvy Mayweather, but it is likely his best bet.

Berto can't out-box one of the greatest boxers in the history of the sport, but he can out-slug him, provided he is able to square him up and neutralize both his quickness and defensive acumen.

That is much easier said than done, but Berto has to believe in his chances or else Mayweather will have already won the fight before it even starts.

Fight Prediction

Of Mayweather's past 13 fights, 11 of them have gone to the scorecards, and while he won all of the bouts, the vast majority of them were won in blowout fashion. Based on recent history, that is the likeliest result for Saturday's contest.

Provided Mayweather is able to avoid getting caught on the chin by Berto's powerful punches, he should have plenty of opportunities to score knockdowns and perhaps even a knockout over the course of the fight. Mayweather rarely seeks out those big moments, though.

While many call Mayweather and his style boring, he is perfectly content to pick apart his opponents with great counters and lightning-quick combinations.

Challengers have seemingly tried every strategy under the sun to throw Mayweather off his game, but he has proven to be unflappable. Whether Berto throws a high volume of punches or takes a methodical approach, Mayweather will almost certainly have an answer.

The fight has a chance to be entertaining if Berto throws caution to the wind, but it will end like a typical Mayweather bout with Money being named the winner by unanimous decision.
