I guess I'll answer my own question
There does appear to be bad weather because the schedule was changed for a third time. They weren't going to use Centre Court today but now they'll use it for two matches.
Alex & Olivier are on court 1
there's one match on 2 and then 2 each on 3 & 4. Hope that makes sense. It's 4:30 AM here and I've been up since 9:30 AM yesterday after going to bed at 5 AM. And I have no plans of getting any sleep till after Alex wins his match
