But I like my picks very much.

Famous last words. At least that's how it goes for me.

I have reduced my slight tennis disadvantage now with Fritz getting eliminated

Now just need Medvedev plus Shelton, should have gone Zverev No too!
You weren't actually at disadvantage as I also had "yes" for Zverev, and since Medvedev also lost, that means you get point from that question.
The more I think, the more I am sure that from now on I will just automatically put "No" to everything for this type of question because more often than not, that brings points, instead wasting time and looking at draws to see who can play against who etc.
