Interestingly, Antonio Restivo, with his fire act, was not with the magicians but part of the "danger" group. Also, Chipps Cooney, who performs a Carl Ballantine-style comedy act and is clearly a comedian and not a magician, was grouped with "magic." He should have been with the comedians.
For the Las Vegas round, the magicians were presented in a collage of heavily edited segments so beyond the particular effect or illusion that they performed, it's difficult to get a handle on their styling and presentation.
William Scott Anderson performed a well known illusion where he separated his body in half. 
Murray Sawchuck went Vegas with a stunning car production.
Michael Grasso, who impressed the judges and audience with a metamorphosis-style illusion in the first round, took a chance and performed an exquisite card manipulation routine that featured colorful parasol productions. Murray Sawchuck commented that the cards can't be seen from the 40th row in an auditorium, but hey, it's good enough for Lance Burton.
Interestingly, Restivo, as part of his fire act, performed the exact same illusion as Michael Grasso did in the first round. We didn't get to see the performance by Frankie Elliston, but in rehearsal, he's shown practicing what looks to be a metamorphosis illusion.
In the end, Murray Sawchuck, Restivo and Chipps Cooney made to the next round. You can watch the magic competition here, as well as the entire show here.

Comments
I was somewhat (ok a lot) disapointed by the Vegas round of competition.
I felt that Antonio had a true Vegas style act and has the potential to do well with it (although, from past shows, we know that America is not looking for magical talent). I believe his fire act would be popular in Vegas.
I enjoyed William’s performance, however, I also think he needs a little more polish before he’s ready for Vegas. he has talent.
Chipps act didn’t really do much for me. Having seen the true genius of Ballantine live (and don’t forget that Ballantine was a skilled magician as well), I was disapponted that Chipps was even considered part of the “magic” group. Howie Mandell had it right when he said Chipps wasn’t a magician, he was a comedian.
Murray’s car production was stunning, but I also felt it was missing something. I suspect that the camera angles had a great deal to do with my feelings.
Which leaves Michael. Without question, Michael has skill. But I think he set himself up for failure in Vegas. He wanted to “show off” his skill, and I feel he forgot it was NOT a magic competition, rather it was generic “talent show”…..and doing a variant of Shimada’s parasol act, combined with card manipulation, on a large stage was just not going to go over well. The performers had something like 3-4 minutes-they had to bring out the WOW factor….and sadly, Michael didn’t “bring it”.
Thanks to the shows such as ‘Americas got Talent’, magic is once again in the public psyche – so there is now a fantastic opportunity for us ALL to: a) show what our art is REALLY about, and b) not only ‘keep mum’ about what we do – but keep TOTAL shtumm about how we do things.
Both Piers Morgan and Sharron Osborne (now there is a woman who knows – ask Ozzy) made very IMPORTANT comment to Jay Madiolli when the hackneyed flags came out – “The whole point of magic is it is supposed to be SURPRISING!” (Morgan); and “Same old – same OLD!” (Osborne).
Here was a guy being offered the opportunity to set up in VEGAS AND be given a MILLION BUCKS – and the best he could do was to reveal a flag! His cheesy comment “As magicians we constantly have to come up with different things (no you do NOT Mr Madiolli!) and “I deliver what is cool and relatable to what people think is cool TODAY.” The act was RELEGATED to the BIN (trash can).

Modern audiences are sooo sophisticated, resent being insulted or made to look foolish, and will VOTE WITH THEIR FEET if you do any of this – so it should be OUT with the ‘put-downs’, ‘puns’ and ‘toilet humour’ – and in with the objective of creating and delivering compelling, entertaining and ENGROSSING magic that the public wishes to experience. Are we are in accord?
‘till the next time’ Levantino out!
