Mayweather vs. Berto Winner: Purse Details and Review of Marquee Fight

Floyd Mayweather triumphed with consummate ease as he dismissed Andre Berto via unanimous decision on Saturday to equal Rocky Marciano's 49-0 winning record.

The judges ruled the 38-year-old to be the winner 117-111, 118-110, 120-108. According to ESPN.com's Dan Rafael, Mayweather will claim $32 million to Berto's $4 million from the final purse, though as Sports Illustrated's Chris Mannix reported the fighter is expecting more than double that figure:

Predictably, the fight was dominated from start to finish by Money as he made full use of the strengths that saw him ease his way through his unbeaten career.

As SHO Stats demonstrated on Twitter, Mayweather was impeccably accurate throughout as he landed over half of the punches he threw:

Likewise, his famously fluid defence was in full flow at the MGM Grand Garden Arena, ensuring his opponent connected with just 83 punches from nearly 500 thrown.

Money showed just why he is considered boxing's best pound-for-pound fighter, repeatedly countering Berto's attempts with pinpoint jabs and mean hooks. Rafael highlighted the huge gap in quality between the two fighters:

By contrast, Berto showed just why he didn't deserve to step into the ring with Mayweather as he struggled to cause him any real problems in a single round, perhaps save for the seventh.

The 32-year-old was unwavering in his approach throughout as he attempted to bring the fight to Money and press him against the ropes.

However, his tactic proved ineffective as Mayweather simply eluded his efforts before responding with his trademark counters. FightNights.com implored Berto to vary his approach, but to no avail:

His inability to adapt made proceedings all the easier for his illustrious opponent, who seemed thoroughly unimpressed by the end of the fight, per Mannix:

The only round in which Berto ran him close was the seventh, in which he opened with a quick right-left combination and finished with a relatively impressive flurry. Even then, though, Mayweather hit Berto square on the nose with a lightning-fast jab, and Rafael still gave the round to Money:

Many were critical of the disappointing clash, which unfortunately lived up to every expectation that it would be a one-sided affair. Mannix in particular was brutal in his assessment of the clash:

Former pro Oscar De La Hoya was similarly scathing:

Per Shaun Al-Shatti of MMAFighting.com, Mayweather reiterated his decision to retire following the fight.

However, the damage such a disappointing final fight could have on his legacy may cause him to come out of retirement and face off against a more difficult opponent.

Likewise, the prospect of further financial reward will naturally prove a hefty incentive to return.

Then again, Mayweather has a history of not caring what others think of him, so like always, he'll ultimately do what he wants, when he wants.
