Mayweather vs. Pacquiao Decision: Judges' Scorecard and Round-by-Round Stats

Floyd Mayweather Jr. and Manny Pacquiao squared off in an epic boxing match on Saturday at MGM Grand Garden Arena in Las Vegas.

Using his trademark technical prowess and outstanding defense, Mayweather improved his record to 48-0, winning by unanimous decision. All three judges scored the fight in Money May's favor, and HBO Boxing had the official scores:

Pacquiao's conservative strategy in the beginning was worth criticizing, as Mayweather's methodical style prevailed and he gained the edge in the first two rounds. Pacquiao then showed signs of life in the next two highlighted by a flurry of punches with Mayweather against the ropes in Round 4.

ESPN's Brian Campbell broke down the sequence and how it altered Mayweather's disposition thereafter:

That was when Pacquiao began to close the gap after it seemed Mayweather would be on his way to a win. From there Pacquiao started taking over and asserting his will against his undefeated adversary.

But Mayweather bounced back to win a tightly contested Round 7 to regain the upper hand entering the latter stages of the action.

CompuBox gave a pretty clear edge to Mayweather, per SI.com's Chris Mannix:

The Wall Street Journal was in agreement with two of the three judges and scored the fight round by round as follows:

Round 1	2	3	4	5	6	7	8	9	10	11	12
Mayweather: 10	10	9	9	10	9	10	10	10	9	10	10
Pacquiao: 9	9	10	10	9	10	9	9	9	10	9	9

Pacquiao did what he could to counter, coming at Mayweather with a dynamic combination of punches while exuding a relaxed countenance. Evander Holyfield weighed in on the action during Round 9 when he felt Mayweather should have attacked more, per SportsCenter:

It seemed close enough entering the final two rounds for Mike Tyson to proclaim that a clear victor hadn't yet been determined.

In the end, Mayweather's sensational defense proved to give him the ever so slight edge over Pacquiao. 

No matter how devastating Pacquiao threatened to be with his speedy combinations, he could never inflict enough damage to knock Mayweather down or gain enough of an advantage to sway the judges.

Dan Rafael of ESPN summarized the conclusion of the fight well in his analysis:

So any chance of a rematch between these two is pretty much extinguished. It took long enough for Mayweather and Pacquiao to meet once. Anyone questioning whether Mayweather is the greatest of his generation needs to look no further than Saturday's outcome.

Mayweather spoke of his plans to retire after the final fight on his current contract in September following Saturday's triumph, per Showtime Sports:

That lengthens the odds even more for a second showdown with Pacquiao. There's no reason for Mayweather to take on Pacquiao again because he's proved he can defeat him and has no need to pass that test once more.

The loss is a tough one for Pacquiao to take. Although he put forth a quality effort and didn't really get hurt too often, he failed to punish Mayweather enough to get the desired result. Every other bout will be anticlimactic from here on out for Pacquiao, whose legacy takes a hit in defeat.
