Han Yan (CHN) won gold at JGP Istanbul last year as a 13-yr-old:

It's too bad he didn't get to do another JGP, he would've probably qualified for the JGPF and done well there!

He's really, really good, only 14 years old (13 in the video)!

Given this is only the third event, hopefully he'll get two this year. He should be a contender for a medal here in Graz.
