Manny Pacquiao certainly came to fight in their epic showdown last Saturday night (May 2, 2015), which took place live on pay-per-view (PPV) from inside the MGM Grand Garden Arena in Las Vegas, Nevada, but he failed where 47 other pugilists have failed before him.

Floyd's defense, as expected, was "Money."
Pacquiao had a couple of big rounds, unloading flurries and landing his share of power punches; however, Mayweather spent most of those minutes covering up and smiling, telling "Pac Man" inside the ring that no, there was nothing there. Not then, not all night.
The judges agreed (see their scorecards here).
Is a rematch possible? Perhaps, considering that Pacquiao thought he won the fight (he didn't do nothing!), though I reckon promoters would have a hard time justifying another $100 price tag for what is likely to make everyone (except the fans) a boat load of money.
Though it should be noted that Mayweather claims he's fighting again in September against an opponent to be named, then calling it quits on his "sweet science" career, citing his advancing age and previous accomplishments inside the squared circle.
We shall see.
