Can't say I'm a tennis fan - in fact I more often than not avoid it if I can - but I did see a bit of this lad season before last when watching the historic Davies Cup victory of ours.
He seemed to have a wonderful forehand shot that made him stand out at the time.
I guess he's added a bit of experience to that now to take him to his first major semi-final.
Even if he goes no further he's done really well and hopefully he will be a power to be reckoned with in years to come.
Three minutes of highlights beating the world number three here -
