Mayweather vs Pacquiao: Paulie Malignaggi calls Pacquiao performance 'pitiful'

It's no secret that former junior welterweight and welterweight titleholder Paulie Malignaggi is one of Manny Pacquiao's biggest critics, often claiming that Pacquiao's rise in weight and success in doing so is suspect. Tonight, with Malignaggi working on the pay-per-view broadcast as an analyst, he got to watch Pacquiao lose to Floyd Mayweather.

And as you might expect, the always-outspoken "Magic Man" got his shots in on Twitter after the fight, which he scored 116-112 for Mayweather:

He also called Pacquiao's reported shoulder injury an "excuse," and "hilarious":

It is also worth noting that Malignaggi recently hired Angel "Memo" Heredia, the controversial strength and conditioning coach who has worked with Juan Manuel Marquez in recent fights.
