LAS VEGAS — Floyd Mayweather Jr. wanted to put on a show and he did, from the moment he entered the arena accompanied by acrobats on stilts tossing fake $100 bills to the final seconds of the 12th round when he finished giving Shane Mosley a beating.

Manny Pacquiao took a break from campaigning for congress in the Philippines to watch on television, and was impressed. So, too, was most everyone at Mayweather's post-fight press conference, though there was some concern over the right hand from Mosley that almost knocked him down in the second round.

"Ain't nothing cool about what happened in the second round," Mayweather agreed.
