Legendary gymnastics coach Bela Karolyi, America’s most decorated gymnast Shannon Miller and USA Gymnastics President Steve Penny were on hand Wednesday to announce that the 2011 AT&T American Cup invitational competition is returning to the Arena March 5. The stop here is one of four on the USA Gymnastics 2011 tour, with Jacksonville joining sites in Glasgow, Scotland; Stuttgart, Germany; and Tokyo, Japan. “You will see the superstars of the 2012 Olympics in London,” said Karolyi. Tickets are on sale now at Ticketmaster outlets and at the Arena box office tomorrow at 10 a.m. The competition was also held in Jacksonville in 2007.
