U.S. Figure Skating has a JGP Mexico wrap story up @ http://www.usfigureskating.org/event_story.asp?id=35505

(Quote from article) Regarding Caroline Zhang's performances at this event: At the end of her program, jubilation surrounded the 4'9” junior high school student, but coach (Ming Zhu) Li declared, “She can be so much better. She was nervous and I could see the muscles were slow. In training she was faster. The altitude made it hard.”

Regarding Caroline Zhang's win at JGP Mexico: One stunned European coach shrugged and said, “They might just as well give her the World Junior gold and let the rest of us have a skate-off for silver.”
