NEW YORK (AP) -- No pressure or anything, Jordyn Wieber.
The last two Olympic gymnastics champions warmed up with a victory at the American Cup a few months before claiming their gold medals. So, too, Mary Lou Retton.
Now it's Wieber's turn. The reigning world champion kicks off her Olympic season Saturday at the American Cup, a chance to give everyone an early reminder that she's the one to beat this summer in London. Retton says a victory would let the rest of the world know Wieber is ready for the Olympics and to "watch out."
