when was the last time pacquiao beat a world class fighter in HIS PRIME?

[S.G.]

You asked who he beat and I'm pretty sure he got a W against Marquez

an official W doesn't necessarily equate to beating the fighter

[FreshPrince]

Corrales, Castillo for starters. Even though I think Castillo won the first fight, he came back the 2nd fight to beat him that time.

For starters? Who else is there?

Yea it does unless it is a DQ

If Pacquiao wins, that would automatically mean that his opponent went old and washed up overnight.

If Pacquiao losses, then his opponent still have it.

For Starters, that's 2 more than Pac. I'm not even a Floyd Stan, just putting my unbiased 2c in it.

Valuev beat Holyfield then i spose

Valuev beat Holyfield then i spose

That is correct

The first barrera fight, Its easy to discredit pacman's wins over morales and JMM but they were still good wins imo, And a victory over Hatton would be good for him because hatton is still 30 and at his best weight which is 140.

Marquez.... that was easy....

And your opinion on it not withstanding, there is a "W" next to Pacquiao's name. See thats how it works, rules say barring a KO, DQ, or someone quitting the fight goes to judges and they decide who wins the fight. We can't just go around changing history, else its not really a sport, its just people giving their opinions.

he beat Marquez twice (well once but everyone knows the judge admitted his screw up in the first fight!)
