Manny Pacquiao and Shane Mosley Arrive at MGM Grand

Manny Pacquiao and "Sugar" Shane Mosley arrived at the MGM Grand this afternoon, the first public event in Las Vegas this week for the May 7 fight between the two stars.

The 39-year-old Shane Mosley arrived first at about 12:20pm local time in Vegas, greeted with boos from Pacquiao fans and some support, of course, from the Mosley rooters in attendance. There did seem to be a section of plants who kept saying in unison, "And the NEEEEEW! Welterweight champion of the world! Sugar! Shane! Mosley!" It didn't exactly come off as spontaneous by the third time they went into the routine.

Ines Sainz of Top Rank talked to Mosley after some photo ops. Mosley said he expects his speed to offset Pacquiao's supposed speed advantage on Saturday, and that he's happy to be in the fight, but wouldn't divulge any game plan notes, as you would expect he wouldn't.

Mosley was asked by another reporter how he would shock the world at age 39, and his response was short and sweet. "By going in there and winning the fight. That's how I shock the world."

"Manny is a great fighter, he's very explosive," Mosley added. "We share a lot of the same qualities."

Pacquiao arrived at about 1:00 local time in Las Vegas, and received a loud reaction from the fans in attendance, and found himself immediately mobbed by international reporters. Pacquiao did his usual skirting around the questions asked of him, expressing great respect for Shane Mosley and the upcoming fight. That's Manny's par for the course, so the lack of great sound bytes should be no surprise.
