I'd noticed Arnoud Mertens! Because my other eldest player, Anton Barth, is the same age but graduated a year later from the junior tour. He's doing exceptionally well for his age group, constantly at the top of the 19-and-under players, although I'd like to think Barth is hot on his heels...
The rate things are going, the pair could be firm rivals for a few years. I notice their head-to-head is one each, with Mertens winning one at Junior level and Barth winning in last week's Shanghai CH3 final...
