But has just finished a tip-top world class degree (four year MSci in Maths from Imperial, London).
Bravo, young man.
Wonder if he's going to try tennis for a year or two ???? Obviously got a lot of room for quick progress - he was only training a couple of times a week for a large part of his course, what with intensive studies etc.
Or is off to some grad programme at some Swanky Banky in September and is just having a summer hol?
