I don't know how many people here play tennis but all the practice serving does not prepare you for doing exactly the same in a competitive match - it's 90% mental. Practice sorts out your mechanics and placement but how you deal with your emotions you can only manage during a match.
I don't so thanks for that bit of advice syc23. Of course, should have realised that.
And good that it does sound like it was first match of the season nerves and more the 2nd than the 1st serve - always an achilles heel for Andy though it had been getting better I felt.
