Thanks for posting the round. I still haven't seen the fight yet, but I'm getting broadband in a few weeks so hopefully I will download it then.
That knockdown at the start should definitely have been called, Floyd's glove definitely touched the canvas.
The 3rd round was definitely Mayweather's though. Zab just seemed to be flicking the jab out aimlessly and not connecting with very much. Floyd landed the more meaningful punches through out.

Can't wait to see the rest of the fight!
