"We have a new technique but I can’t say because it’s a secret," said Pacquiao in English moments before capping his Saturday afternoon workout at the Wild Card Boxing Club.

After performing in front of a huge crowd on Thursday, Pacquiao worked out in private the next two days and plans to do the same when he trains for the last time on Monday, the day he leaves for Sin City where a grand welcome typical of the gambling capital’s opulence awaits him at the Wynn Resort and Casino at 7:30 p.m.

TV crews from the Philippines and photographers have not been spotted following the media workout, a testament to Roach’s firm order that nobody without official business be allowed to get a sneak-peek between 1 to 3 p.m.

A shaven-skulled fellow named Rob Thomas has been tapped to secure the sweat shop that has become a Hollywood landmark for fans of the fight game.

"While Manny likes to perform in front of an audience, he likewise likes the idea of training in a situation as calm as this," said Roach when the Bulletin was given the opportunity to observe the training.

Roach said he "doesn’t want to ruin six weeks of hard training" by disrupting Pacquiao’s training.

"We worked very hard the last six weeks," said Roach, who has been with Pacquiao the last six years.

But it’s no secret that Pacquiao is also trying to harness the power in his right hand so he won’t rely too much on his left.

"I’ve been telling him to throw his right more often to give him confidence. It could be the key (to winning the fight)," added Roach, who remains confident that the Filipino lefty has what it takes to become the first fighter to stop Morales.

Morales, who is also deep in training in Queretaro, 200 kilometers northwest of Mexico City, is arriving in Las Vegas on Tuesday on board a private jet with his entourage.

Morales, who narrowly defeated Pacquiao in their first meeting last year at the MGM Grand, has also vowed to put on a splendid show.

This is going to be Pacquiao’s ninth fight in the US after a rousing debut against Lehlo Ledwaba in June 2001. His record on American soil is 5-1-2 (win-loss-draw) with all victories coming by knockout.

Meanwhile, super-featherweight Jimrex Jaca will clash with Hispanic slugger John Nolasco in an eight-rounder underneath the Pacquiao-Morales undercard.

Jaca is a former Philippine and Orient-Pacific Boxing Federation titleholder and is a protégé of Wakee Salud, a trusted ally of Pacquiao.
