Looks like Manny Pacquiao is finished.

[Loy Toy]

Round 1: Pacquiao, as expected, opens as the aggressor. Marquez and Pacquiao pawing with jabs and Pacquiao lands a very good left. Another good left and they're trading shots. Another good left and uppercut by Pacquiao.

Round 3: Marquez wings a left hook and it's blocked. PAcquiao is aggressing, but a little more measured. Right and a left for Pacquiao lands. Good left to the body for Marquez. And another. Huge overhand right floors Pacquiao. That's a real knockdown. Pacquiao pushing forward, but no they're swinging in the middle.

Round 4: Pacquiao still aggressing, but so far nothing major in this round. Both fighters trade lead hands. Pacquiao pushing in, but eats a counter shot from Marquez. Good, short punches inside by the Filipino. The fighters again trade shots in the middle, but Marquez gets the better of them generally speaking.

Round 5: Good left from Pacquiao as he scores the first shot of the round. Left hand drops Marquez and that's a knockdown. Pacquiao eats another shot, but this is still his round...so far. Pacquiao eats a left but he he's still pushing forward. This is incredible. These two are eating what can only be described as unreal.

Round 6: A Manny flurry lands hard, but Marquez responds with a left of his own. Pacquiao lands repeatedly with punch combinations and then angle cuts. Pacquiao really putting the pressure on Marquez trying to put him against the ropes. Big left partially wobbles Marquez until he hits Pacquiao with a MONSTER left that puts Pacquiao down. He is out COLD. Unbelievable. Marquez has KO'd him flat cold.

Round house K.O., happens to the best of em. Ali and Spinks? Ali called Spinks the vampire as he only had one or two teeth.

I dont know, he was busting up Marquez and it was a war. Then at 2:59 he got crunched with a punch he never saw. He was ahead in the fight though. 20 million bucks for this one even though no belt was involved. Perhaps it is time to hang it up, but he was not beaten up. He just simply was knocked stone cold out.

[alwarner]

He's a had a few funny results lately.

IMO he didn't beat Marquez last time and he should have beaten Bradley.

He looked invincible for a while there but he's past his best now.

Agreed. He has been fighting hard Championship fights for over 10 years now, and moving through a record number of weight classes as well. This is bound to take it's toll eventually.
He was robbed (of his titles) against Bradley in his last fight though, most shameful decision I've ever seen in boxing.. Against a fighter who can't even sell out car parks in his own city.
Having said that, it was a real tear-up of a fight between him and Marquez, and until the knockout (hell of a punch), he was doing a number on his most famous adversary, busting him up pretty badly like AO stated.

Unfortunately, this probably means that he will be out of the frame against the fighter that every boxing fan wanted to see him face, Floyd Mayweather.

I think it was a monster right.

And all the talk about one of Marquez's trainers having been in trouble for supplying performance enhancing drugs before (to Marquez?), was there with Marquez as a sign...to mess with the heads of Pacquiao and company?, or was he giving Marquez the secret strongman juice?...Marquez looked like a weight class above Pacquiao, and the extra weight looked all muscle.

Pacquiao is going to get brain damage if he continues. He may have it already anyway, plus that Marquez shot was a terrible blow to the head (watch it in non-slow motion!), and Pacquiao was on the canvas for a long time.
