Mayweather vs. Pacquiao Highlights: Full Recap of Pretty Boy's Impressive Win

Floyd Mayweather Jr. proved once and for all on Saturday night that he is the premier boxer of his era as he convincingly beat Manny Pacquiao by unanimous decision in Las Vegas.

After an almighty buildup to boxing's richest-ever fight at the MGM Grand Garden Arena, Mayweather extended his undefeated record to 48-0 with a tactical masterclass against Pacquiao.

The American started the better of the two fighters, and although he was rocked a couple of times in the middle rounds, he finished strongly to secure victory.

Bleacher Report UK reported the judges' scores, which mean Mayweather is now the unified WBC, WBA and WBO welterweight champion:

The 38-year-old Mayweather had the better of the opening two rounds as he landed a handful of clear right hands on Pacquiao. His famous slip-and-rip tactics were on full show as he stamped his authority on his rival.

Pac-Man then came into the fight in the third and rocked Mayweather with a big left hand in the fourth. Money was momentarily forced back onto the ropes and took a flurry of punches to the arms and gloves as he looked to protect himself.

For the first time in the fight, the elusive American needed to weather a storm.

He was not on the back foot for long, though, as he came back to take the fifth, once again popping the jab and finding a home for the straight right, which carried spite all night.

Pacquiao did land heavily again on Mayweather in the sixth, however, per ESPN's Dan Rafael:

From then on, though, Mayweather was largely untouchable. He seemed to work Pacquiao out for the second half of the fight, ducking and weaving with great success to the frustration of his opponent.

Pacquiao looked to tire, and as he missed more often, Mayweather's jabs continued to land, until the fight was effectively out of reach for the Filipino barring a hugely unlikely knockout, per SuperSport's Colin Udoh:

Pacquiao looked spent in the final round, barely attempting a late rally, and Mayweather's raised hand of triumph just before the final bell rang was far from presumptuous.

As noted by boxing analyst Corey Erdman, Mayweather was largely dominant and rarely troubled, per Bleacher Report:

Mayweather seemed to tower over Pacquiao for much of the fight, and his superior reach proved vital as he landed significant straight right hands.

He was elusive and fast, continuously ducking away from Pacquiao's attempts to land telling combinations.

Mayweather said after the fight he will return to the ring only one more time before he retires, per Sky Sports: "My last fight is in September and after that, I am hanging them up."

Four-time world champion Carl Froch showered praise on Mayweather following the fight:

After Saturday's victory, there is now little question as to Money's place in the history books. Speculation had been rife during his career that Pacquiao would be the one to finally beat Mayweather.

That theory was found wanting on Saturday, after a tactical masterclass from Mayweather left Pac-Man with no response.
