Mayweather vs. Berto: Updated Odds, Undercard and Main Event Predictions

In what Floyd "Money" Mayweather Jr. has said will be the final fight of his career, the 48-0 legend will take on Andre "The Beast" Berto Saturday night as part of a card that promises to entertain boxing fans from top to bottom.

Few are giving Berto a chance to blemish Mayweather's perfect record, and while a win over Money would admittedly be one of the greatest upsets in boxing history, his free-wheeling style means it should be a fun fight to watch even if the 38-year-old favorite is dominant.

In addition to Mayweather versus Berto, there are three undercard bouts that have the potential to steal the show. Many have questioned if the event is worth purchasing on pay-per-view, but it is tough to argue with the overall depth and quality of the fights.

With Mayweather's last fight on the horizon, here is a rundown of the entire card, along with predictions for how the main event will play out.

Keys to Mayweather Victory

While few consider Mayweather to be among the most exciting boxers of all time, it is difficult to argue with the notion that he is one of the best due to his quickness, evasiveness, hand speed and ability to counterpunch.

All of those assets give him an advantage whenever he steps into the ring regardless of his opponent. That will be especially true Saturday when he takes on a fighter in Berto who simply can't come close to matching Mayweather's resume.

As seen in this tweet courtesy of ESPN Stats and Info, there is no question that this contest is a mismatch in favor of the WBC, WBA (Super) and The Ring Welterweight champion:

Mayweather is so heavily favored, in fact, that many within the boxing business are shaking their heads at his choice of opponent. ESPN's Dan Rafael is chief among them:

After Mayweather's decimation of Manny Pacquiao, it is tough to blame him for settling on Berto. Pac-Man was viewed by many as the only boxer with a chance at stopping Mayweather's run toward an undefeated career, but he was thoroughly dominated in what was supposed to be the fight of the century.

Mayweather has proved everything he needs to prove, and he is supremely confident that Saturday's bout will play out like every other professional fight he has been a part of, according to BoxingInsider.com:

One can only assume that Berto will be aggressive in hopes of scoring a lucky knockout. That will leave him wide open to Mayweather's impeccable countering abilities, and it is likely that a knockout will be there for the taking if he chooses to go that route.

Only two of Mayweather's past 13 fights have gone less than 12 rounds, though, which means there is little incentive for him to go for the gusto.

Mayweather thrives at picking his opponents apart and winning handily on the scorecards, and as long as he remains smart and patient throughout his contest with Berto, that is the likeliest result.

Plenty have argued that Berto doesn't deserve to be in this position, but that plays right into his hands. He has nothing to lose in going up against a undefeated and all-time great boxer in his final fight.

Expectations are extremely low for The Beast, which means he can throw caution to the wind and throw everything he has at Mayweather. While that probably still won't be enough, Berto is a powerful puncher who could catch the champ with a devastating blow.

Despite the odds seemingly being stacked against him, Berto believes he has what it takes to shock the world when he goes toe-to-toe with Mayweather:

Many have talked trash in Mayweather's direction over the years only to come up woefully short, but that hasn't stopped Berto from expressing his confidence through the media.

According to Rafael, Berto intends to send the undefeated superstar to the mat when they finally meet in Las Vegas.

"I'm coming to kick Floyd's ass on Sept. 12," Berto said. "Best believe that I plan to bring it to Floyd and I'm not concerned about what 48 other fighters have been unable to do. Somebody is getting knocked out, and it won't be me. You don't want to miss this."

Unlike Mayweather, Berto is a fighter who seeks knockouts. Of his 30 career victories, 23 of them have come in that manner.

Due to the wide-open style that is likely to be utilized Saturday night, even Mayweather has outwardly suggested that the bout may not go the distance, per Greg Beacham of the Associated Press.

"With the way he comes, and with the way I'm going to come, if it's not a knockout, there's going to be some knockdowns," Mayweather said. "A lot. And there's going to be blood. There's going to be knockdowns, and there's going to be blood. A lot."

There is no doubt that Berto will leave himself susceptible to getting knocked down and knocked out if he goes for a knockout in his own right, but the odds of him outboxing Mayweather and beating him in the eyes of the judges are slim and none.

Regardless of how risky it may be, Berto has to throw the kitchen sink at Mayweather and attempt to put him down for the 10 count.

Main Event Prediction

There will be no shortage of pressure on Mayweather to perform Saturday night, since a perfect career mark is on the line, but based on how he dominated Pacquiao in his most recent bout, it would be crazy to pick against Money.

Despite the criticism of Berto as his opponent, Mayweather is sticking his neck out there and risking his undefeated record each and every time he steps into the ring.

It doesn't seem there is anyone capable of beating him at this point, but Berto may have as good of a chance as anyone due to his pure punching power.

It's tough to knock someone out when they rarely get hit, though, and this is why Mayweather will thrive and ultimately win this fight.

Even though there has been plenty of talk about knockdowns and knockouts from both camps, that simply isn't Mayweather's style at this point in his career.

He'll be perfectly content to pick Berto apart, and that will lead to a unanimous decision victory and perhaps even an across-the-board shutout on the judges' scorecards.
