I'm pretty sure I know who Bill's talking about -- he's 15, I think (may have turned 16 by now). He's listed in the Worlds invites in MJ2, which means he was born in 1994 or later. And he's got tons of potential -- factored into his rating are several tournament rounds, in solid competition, that were rated 950 or above, including one 972, one 971 (in the same event) and a handful of rounds in the 960s. He outdid himself a couple of weeks ago and shot a 1007 rated round in the second round of a tourney in bad weather conditions -- second best round of the day for anyone. He won Int (for the second year in a row at this event), would have won Adv, and would have finished second in Open (yes, they all played the same layout). That event was after the cutoff for this rating update by just a few days, so you should expect to see him move up significantly next time.
The scary thing is, from my conversations with his dad at various events, he's not even taking it all that seriously right now -- he only played a couple of events the second half of last year. But it was clear when I played in the same group with him back in Oct 2007 (I was playing with a juniors group as a nominally responsible adult to keep an eye on things) that he was something special. And last summer, he deuced 9 out of 10 consecutive holes in a juniors event that I ran. He's not David Wiggins, but he can definitely expect to play competitively at the top level as soon as he decides to do so.
