I don't know if you guys have seen this, but we have a Junior who is only 13, but appears to be the real deal. Denis Shapovalov was runner up at U18 provincials, and this week made it to the QF's of singles and doubles at the G5 Junior Tournament. This will make him the 3rd highest ranked player born in 1999 in the world. I know it's too young to start judging, but I definitely feel like he's someone to keep an eye on. He's a lefty with a one-handed backhand, who's coached by his mother.
I saw him play a couple of weeks ago at the U16 nationals, where he finished 5th. Definetly has potential, and hits a nice and clean ball. I didn't know he was 13 though, that looks promising.
