I was just wondering the same thing.
Kuzuhara is into the finals of both boys singles and doubles at the Australian Open.
Is he another Noah Rubin (former Wimbledon boy's champ with a career high ranking of #125 in the pros) or does the kid have top 50 pro potential?
I also saw that Kuzuhara is coached by Brian Baker, which is a name from the past. Baker won the Orange Bowl and was a French Open finalist in boy's singles, beating Baghdatis and Tsonga along the way, and losing the championship to Wawrinka. However, he was plagued with injuries as a pro. Still, he bagged over $1 million in prize money, which isn't bad for a guy that most people don't know about.
