What a day. I enjoyed sitting in the commentary box watching Andy Murray - his effort, emotion and the enjoyment he showed.
The future is bright for this young man. It has been an incredible ride for him since winning the US Open juniors.
His game has gone to a different level, but now he has to remember what he has done to get to this level and understand what it will take to get to the next level and be able to compete against these players week after week.
You just can't rush someone along. You have to nurture them to bring them along slowly so that they are not just here today and gone tomorrow.
We've seen too many players who that has happened to in the past.
I think what was enjoyable for me was when he showed his emotion out on Centre Court.
Hats off to David Nalbandian, though. I thought the occasion might be too much for him, but he showed guts and heart.
It's the first time he's come back from two sets down and that will be a big boost for him.
Andy will have time to reflect and be part of the tournament as a spectator.
Having played in a five-setter and having found himself two sets to love up means that his mind will be spinning as to what it will take to win these types of matches in the future.
But he shouldn't stress about it - he lost a match so he just has to get on with it and he is still young.
Andy's game is there. He's got all the shots, he has power, he has finesse, he has a very good first serve. His whole game as an 18-year-old is very mature.
So what will it take to improve?
Maybe a little bit more work on the court to improve his conditioning and strength.
Once he can incorporate that into this game, then he will be spectacular.
